Abstract

We present the results of a single-pointing survey of 207 dense cores embedded in Planck Galactic Cold Clumps distributed in five different environments (λ Orionis, Orion A, Orion B, the Galactic plane, and high latitudes) to identify dense cores on the verge of star formation for the study of the initial conditions of star formation. We observed these cores in eight molecular lines at 76–94 GHz using the Nobeyama 45 m telescope. We find that early-type molecules (e.g., CCS) have low detection rates and that late-type molecules (e.g., N₂H⁺ and c-C₃H₂) and deuterated molecules (e.g., N₂D⁺ and DNC) have high detection rates, suggesting that most of the cores are chemically evolved. The deuterium fraction (D/H) is found to decrease with increasing distance, indicating that it suffers from differential beam dilution between the D/H pair of lines for distant cores (>1 kpc). For λ Orionis, Orion A, and Orion B located at similar distances, D/H is not significantly different, suggesting that there is no systematic difference in the observed chemical properties among these three regions. We identify at least eight high-D/H cores in the Orion region and two at high latitudes, which are most likely to be close to the onset of star formation. There is no clear evidence of the evolutionary change in turbulence during the starless phase, suggesting that the dissipation of turbulence is not a major mechanism for the beginning of star formation as judged from observations with a beam size of 0.04 pc.

1. Introduction

In the process of star formation, the initial condition is believed
to determine what kinds of stars will be born and how they will
form (e.g., Bergin & Tafalla 2007; McKee & Ostriker 2007).

However, the details of initial conditions have not been
thoroughly characterized.

Stars are formed through gravitational collapse in dense
molecular cores (e.g., Bergin & Tafalla 2007; McKee &
Ostriker 2007), and many observations have reported that the
core mass function is similar in shape to the initial mass function (IMF; e.g., André et al. 2010; Könyves et al. 2010). However, this is not the case in high-mass regimes, where deviations from the Salpeter IMF have been recently found (e.g., Zhang et al. 2015; Motte et al. 2018; Sanhueza et al. 2019). These studies suggest that studying dense cores in different mass ranges may provide valuable information on the initial conditions of star formation. Furthermore, we need to take care of the evolution in the starless phase because the internal structure of dense cores is altered physically and chemically during the core evolution (Aikawa et al. 2008). Therefore, the identification of the dense core *just prior to* the beginning of gravitational collapse, which we call “prestellar core” here, is essential in understanding the genuine initial conditions of star formation (e.g., Ohashi et al. 2018).

In low-mass star-forming regions, prestellar cores are not only compact ($\lesssim$0.1 pc), cold ($\lesssim$10 K), and dense ($>5 \times 10^4$ cm$^{-3}$) (e.g., Bergin & Tafalla 2007; McKee & Ostriker 2007) but also gravitationally bound, thermally supported, and centrally concentrated (e.g., Ward-Thompson et al. 1994; Caselli 2011). For high-mass star formation, prestellar cores are as massive as at least 30 $M_\odot$, assuming a star formation efficiency of 30% (Wang et al. 2014; Sanhueza et al. 2019).

The chemical characteristic of starless cores close to the onset of star formation is high deuterium fractionation. The deuterium fraction (D/H hereafter) is defined as a column density ratio of a deuterated molecule to its hydrogenated counterpart and has commonly been used to study the chemical properties of dense cores in low- and high-mass star-forming regions (e.g., Hirota et al. 2001; Crapsi et al. 2005; Hirota & Yamamoto 2006; Bergin & Tafalla 2007; Chen et al. 2010, 2011; Fontani et al. 2011; Sakai et al. 2012, 2015, 2018; Feng et al. 2019).

The chemical evolution of a dense core in terms of D/H can be described as follows. As a dense core evolves toward gravitational collapse, it develops a steep radial density profile that increases toward the core center and a radial temperature profile that decreases toward the core center (e.g., Crapsi et al. 2007; Aikawa et al. 2008). At the core center ($\lesssim$5000 au) with low temperature ($T_{\text{dust}} \lesssim 25$ K and often closer to 10 K) and high density ($n_{\text{H}_2} \gtrsim 10^4$ cm$^{-3}$), CO molecules (a destroyer of deuterated molecules) become frozen on the surface of the dust grain, and the enrichment of deuterated molecules is activated with exothermic ion-molecule reactions from HD molecules (e.g., Millar et al. 1989; Phillips & Vastel 2003; Vastel et al. 2004; Aikawa et al. 2005; Crapsi et al. 2005). When a protostar is born at the core center, it heats up the surroundings (e.g., Caselli et al. 2002b). At the warm ($T_{\text{dust}} \gtrsim 25$ K) core center, CO molecules are desorbed from the grain surface and then destroy deuterated molecules (Roberts & Millar 2000; Lee et al. 2004). Therefore, D/H varies with temperature. If the core is cold enough ($T_{\text{dust}} < 25$ K), D/H increases in the starless phase and reaches its maximum at the onset of star formation, and then it decreases by an order of magnitude after star formation (e.g., Hirota et al. 2003; Crapsi et al. 2005; Emprechtinger et al. 2009; Friesen et al. 2010; Sakai et al. 2012; Fontani et al. 2014).

$N(\text{DNC})/N(\text{HNC})$ and $N(\text{N}_2\text{D}^+)/N(\text{N}_2\text{H}^+)$ can be used as D/H tracers. $N_2D^+$ is known to be the least depleted molecule (Pagani et al. 2007), and DNC is known to trace cold molecular gas (Gerner et al. 2015). The destruction timescale of the DNC molecule is known to be much longer than that of the $N_2D^+$ molecule (e.g., Sakai et al. 2012; Fontani et al. 2014). For

example, after stellar birth, $N(\text{N}_2\text{D}^+)/N(\text{N}_2\text{H}^+)$ decreases within 100 yr, whereas $N(\text{DNC})/N(\text{HNC})$ drops at a timescale of $10^4$ yr. Fontani et al. (2014) showed that the deuterium fractionation of $N_2H^+$ is more suitable than that of HNC to identify cores on the verge of star formation in high-mass star-forming regions.

For the chemical evolution of the dense core, it is also noticed that the abundance of gas-phase molecules decreases at different timescales because of adsorption and/or chemical reactions in the central dense region of the core (Aikawa et al. 2001, 2003; Lee et al. 2003). For example, carbon-chain molecules (e.g., CCS and HC₃N) are abundant in starless cores, whereas c-C₃H₂ and nitrogen-bearing molecules (e.g., N₂H⁺ and NH₃) are abundant in protostellar cores (e.g., Suzuki et al. 1992; Benson et al. 1998; Ohashi et al. 2014, 2016). That is, CCS molecules are known as “early-type species,” and c-C₃H₂, N₂H⁺, and NH₃ molecules are known as “late-type species.” This means that *chemically evolved* cores have lower abundances of C-chain molecules and higher abundances of c-C₃H₂ and N-bearing molecules. $N(\text{N}_2\text{H}^+)/N(\text{CCS})$ and $N(\text{N}_2\text{H}^+)/N(\text{HC}_3\text{N})$ can be valid chemical evolution tracers at a spatial size scale of ~0.1 pc for cold ($T_{\text{dust}} \lesssim 25$ K) cores. These ratios are invalid as evolution tracers for warm (>25 K) cores, because the $N_2H^+$ molecule is destroyed by CO desorption (e.g., Aikawa et al. 2001, 2003; Lee et al. 2003; Tatematsu et al. 2014).

Measurements of the column density ratios of deuterated/hydrogenated molecules and N-bearing/C-chain molecules provide a useful tool to characterize the evolutionary status of the dense core in which a star will form (e.g., Hirota & Yamamoto 2006). In this paper, HC₃N is regarded as a C-chain molecule rather than an N-bearing molecule. Taking chemical evolution into account, Tatematsu et al. (2017) introduced the chemical evolution factor (CEF) as a comprehensive diagnostic tool for the degree of evolution of dense cores. The CEF is defined so that when a dense core evolves the CEF monotonically increases from ~-100 for a starless core to ~100 for a protostellar core through zero corresponding to the onset of star formation (See Section 4.1). The first attempt was made toward low-mass starless cores in nearby cold clouds in the literature (Tatematsu et al. 2017), but the CEF should be established for other environments (e.g., distant high-mass starless cores) by increasing sample numbers.

Efforts toward the identification of dense cores over all sky have extended from optical to infrared wavelengths with instrumental development (e.g., dark cloud in DSS and infrared dark cloud in MSX and Spitzer; Lee & Myers 1999; Simon et al. 2006; Peretto & Fuller 2009; Kim et al. 2010; Dobashi 2011). Most recently, the Planck all-sky survey has been made and provides a catalog of Planck Galactic Cold Clumps (PGCCs; Planck Collaboration et al. 2011, 2016), which includes 13,188 sources of ~5'- to 10'-sized structures or “clumps” with temperatures of 10-20 K in various environments. An unbiased selection of PGCCs was mapped with Herschel in the far-IR band (e.g., Juvela et al. 2010, 2012, 2018). A series of follow-up observations have been conducted with ground-based radio telescopes such as PMO, CSO, SMT, APEX, NANTEN2, IRAM, Mopra, Effelsberg, SMA, the James Clerk Maxwell telescope (JCMT), and TRAO and are summarized by Liu et al. (2015, 2018). Specifically, the JCMT large program “SCUBA-2 Continuum Observations of Pre-protostellar Evolution (SCOPE)” identified ~20”- to 60”-sized structures or “cores” within PGCCs
(Liu et al. 2018). These PGCC cores are distributed in low/
high-mass star-forming regions from the Galactic plane to high
latitudes (Eden et al. 2019). The initial conditions of star
formation in these various environments are still poorly
understood. For example, the initial conditions of high-mass
star formation are poorly known and debatable because of the
small numbers of massive prestellar cores in high-mass star-
forming regions so far identified (e.g., Wang et al. 2014;
Sanhueza et al. 2017, 2019; Contreras et al. 2018) because of
their large distances and short evolutionary timescale (McKee
& Ostriker 2007; Caselli 2011). These PGCC cores can be
valuable targets not only to assess evolutionary stages on the
basis of the column density ratios of D/H and N-bearing/C-
chain molecules but also to study the initial conditions of star
formation in widely different environments.

Our ultimate goal is to explore the details of the initial
conditions for star formation based on the physical and
chemical properties of prestellar cores in various environments.
The first step is to identify reliable samples of such dense
cores. Thus, we report the first stage of our research with
single-pointing observations of 207 cores in PGCCs in the
molecular lines of N<sub>2</sub>D<sup>+</sup> *J* = 1–0, N<sub>2</sub>H<sup>+</sup> *J* = 1–0, DNC
*J* = 1–0, HN<sup>13</sup>C *J* = 1–0, CCS *J*<sub>N</sub> = 7<sub>6</sub>–6<sub>5</sub>, CCS *J*<sub>N</sub> =
8<sub>7</sub>–7<sub>6</sub>, HC<sub>3</sub>N *J* = 9–8, and c-C<sub>3</sub>H<sub>2</sub> *J*<sub>K<sub>6</sub>K<sub>5</sub></sub> = 2<sub>12</sub> – 1<sub>01</sub> with
the 45 m single-dish telescope of the Nobeyama Radio
Observatory.<sup>29</sup> Cores found in this study are in the chemically
evolved stage of starless cores (late starless cores hereafter) as
prestellar core candidates. In the next paper, we will investigate
whether these late starless cores are actually prestellar cores or
not through mapping observations.

This study is organized as follows: observations and data
analysis procedures are described in Section 2, the observational
results are presented in Section 3, Section 4 presents the
identification of late starless cores in various environments using
the CEF and D/H, and the study is summarized in Section 5.

**2. Observations and Data Analysis Procedure**

2.1. Sample Selection

The SCOPE survey discovered more than 3000 PGCC cores
across the Galaxy at 850 µm with SCUBA-2 (Submillimetre
Common-User Bolometer Array 2) on board JCMT (e.g., Yi
et al. 2018; Eden et al. 2019). Yi et al. (2018) identified 119
cores embedded in 96 PGCCs in the Orion region from JCMT
SCOPE data and JCMT archive data. Eden et al. (2019)
released a compact source catalog using the JCMT SCOPE
data, which contains 3528 cores identified in 1235 PGCCs
from the Galactic plane to high latitudes. As a pilot study, we
selected a total of 207 targets that are located at different
Galactic positions (local Giant Molecular Clouds [GMCs], high
latitude, and Galactic plane). These dense cores are among the
densest cores (N(H₂) > 1 × 10²² cm⁻²) discovered in the
SCOPE survey and consist of 113 cores in the Orion region,
which is associated with GMCs, 52 cores in the Galactic plane
(|b| < 2°), and 42 cores at high latitudes (|b| ≥ 2°). Figure 1
shows the Galactic distribution of 207 SCUBA-2 cores, and the
information on the targets is summarized in Table 1 with the
core name, coordinate, dust temperature, H₂ column density,
type of environment, and the related PGCC. The dust
temperature is taken from the PGCC catalog, and the H₂

column density is derived from the 850 µm peak intensity of
the PGCC core (Yi et al. 2018; Eden et al. 2019) and the dust
temperature. The 207 SCUBA-2 cores have dust temperatures
ranging from 9.2 to 22.4 K with a median value of 13.3 K.
They have H₂ column densities of (0.17–12) × 10²³ cm⁻² with
a median value of 8.2 × 10²² cm⁻².

We investigate environments surrounding SCUBA-2 cores using the SIMBAD database. The Orion region, including the 113 SCUBA-2 cores, is a local active star-forming region where both massive stars and low-mass stars are born (e.g., Yi et al. 2018). This region consists of λ Orionis, Orion A, and Orion B subregions, which include GMCs and many star-forming regions such as H II regions (e.g., LDN 1641 S3), star clusters (e.g., Collinder 69, Orion Nebula Cluster, NGC 2023, and OMC 2), and nebulae (e.g., Orion KL, McNeil Nebula, and IC 432). A total of 15, 70, and 28 SCUBA-2 cores are located in λ Orionis, Orion A, and Orion B, respectively, and their distributions are shown in Figure 2. Yi et al. (2018) found that the physical properties of the SCUBA-2 cores in the three subregions are different. The SCUBA-2 cores correspond to part of the dark clouds (e.g., L1581, L1582, L1594, L1598, L1630, and L1641).

The 52 SCUBA-2 cores in the Galactic plane are located in the vicinity of open clusters (e.g., NGC 2264, NGC 6530, and NGC 6611) and supernova remnants (e.g., W48) and are embedded in dark clouds (e.g., L463). The 42 SCUBA-2 cores at high latitudes seem to be associated with famous star-forming regions (e.g., Auriga, California, Cepheus, Cygnus, IC 5146, Ophiuchus, Perseus, and Taurus), nearby dark clouds (e.g., Banard 1, L43, L183, L769, L944, L973, L1004, L1181, L1204, L1035, L1521F, and L1525), open clusters (e.g., NGC 2264), and star clusters (e.g., NGC 7129).

The information on these environments is listed in Table 1.
We consider λ Orionis, Orion A, Orion B, the Galactic plane,
and high latitudes as five different environments.

2.2. Single-pointing Observations

We carried out single-pointing observations toward the 850 µm intensity peak position of 207 SCUBA-2 cores with the 45 m single-dish radio telescope of the Nobeyama Radio Observatory from 2017 February to 2018 May (CG161004, LP177001; P.I.: K. Tatematsu). One of the two-sideband SIS receivers, T70 or TZ, was used for simultaneous four-line observations in the double-polarization mode (Asayama & Nakajima 2013; Nakajima et al. 2013). The T70 receiver was adopted for observations toward all 207 SCUBA-2 cores in the c-C₃H₂ *J*<sub>K<sub>6</sub>K<sub>5</sub></sub> = 2<sub>12</sub> – 1<sub>01</sub>, DNC *J* = 1–0, HN<sup>13</sup>C *J* = 1–0, and N<sub>2</sub>D<sup>+</sup> *J* = 1–0 molecular emission lines. The TZ receiver was used for observations toward 111 SCUBA-2 cores in the Orion region in the CCS *J*<sub>N</sub> = 7<sub>6</sub>–6<sub>5</sub> (CCS-L hereafter), CCS *J*<sub>N</sub> = 8<sub>7</sub>–7<sub>6</sub> (CCS-H hereafter), HC<sub>3</sub>N *J* = 9–8, and N<sub>2</sub>H<sup>+</sup> *J* = 1–0 lines. Observations with the TZ receiver were not conducted for two Orion cores and all cores in environments other than the Orion region owing to time limitations. The rest frequencies and their references, upper energy levels, and employed receivers of the eight lines are listed in Table 2. At 82 GHz, the half-power beam widths (HPBW) of the T70 and TZ receivers are 19 ′′ 5 ± 0 ′′ 3 and 18 ′′ 8 ± 0 ′′ 1, respectively. Their main-beam efficiencies η<sub>mb</sub> are 54.7% ± 3.5% and 55.4% ± 3.5%, respectively. The FX digital spectrometer SAM45 (Kamazaki et al. 2012) was employed with a spectral resolution of 15.26 kHz (corresponding to ~0.06 km s<sup>-1</sup> at

82 GHz) for 113 SCUBA-2 cores in the Orion region and 30.52 kHz (corresponding to ~0.1 km s⁻¹ at 82 GHz) for the remaining 94 cores. The use of two different spectral resolutions was accidental. The system temperature was typically 200 K.

Single-pointing observation for each core typically took ~30 minutes, including the telescope overhead time in the position-switching mode, to achieve 0.09 K rms sensitivity at a resolution of 0.1 km s⁻¹. The telescope pointing uncertainty was established as ≲5″ through five-point measurement toward 43 GHz SiO maser sources close to targets every ~1–1.5 hr. The resulting spectrum is expressed in terms of the antenna temperature corrected for atmosphere extinction $T_A^*$ obtained by the standard chopper wheel calibration. For the reduction of raw data, the baselines are subtracted and then the spectra are co-added on the software package “NEWSTAR”<fnref n="30" /> of the Nobeyama Radio Observatory. The reduced data are transferred into a data format of the GILDAS CLASS program<fnref n="31" /> and are resampled into a 0.1 km s⁻¹ velocity resolution.

## 2.3. Gaussian or Hyperfine Structure Fitting to a Spectrum

Figure 3 shows the spectra of four or eight molecular emission lines for SCUBA-2 cores. N₂H⁺ and N₂D⁺ lines show the seven components of hyperfine transitions<fnref n="32" /> (e.g., Caselli et al. 2002b), but the other lines generally exhibit a single velocity component. For a further analysis, we make a Gaussian (GA) or hyperfine structure (HFS) fitting to each spectrum using the GILDAS CLASS program. For c-C₃H₂, CCS, and HC₃N lines having single Gaussian shapes, we apply the GA fitting to them to measure the peak temperature ($T_{peak}$), systemic velocity ($V_{LSR}$), and line width ($\Delta v$) in FWHM. DNC and HN¹³C lines look like single Gaussian shapes, but they are known to have four and six components of hyperfine transitions, respectively (van der Tak et al. 2009). Because our main purpose is to derive the column density, for simplicity we ignore the hyperfine splitting for DNC and HN¹³C, and apply simple Gaussian fitting. The derived line widths of both lines are overestimated for this reason. For N₂D⁺ and N₂H⁺ lines, where the seven components of hyperfine transitions are clearly visible, we apply the HFS fitting to them to obtain the excitation temperature ($T_{ex}$), $V_{LSR}$, $\Delta v$, optical depth ($\tau$), and $T_{ant}\tau$. To obtain $T_{peak}$ and $\Delta v$ of the brightest component ($JF_I F = 123-012$) of the N₂H⁺ and N₂D⁺ lines, we apply the

GA fitting to the brightest component of the lines. We measure the rms (σ) noise level from the baseline subtraction procedure for the spectrum. The fitting results are listed in Tables 3 and 4. We regard the peak temperature higher than 3σ as detection for further analysis. Otherwise, we give 3σ as an upper limit and consider it as a nondetection.

## 2.4. Distance of 207 SCUBA-2 Cores

Accurate distances of cores are often unavailable because of the lack of references. When an accurate distance to the parent cloud is known in the literature, we adopt the value. Otherwise, we employ distance from the parallax-based distance estimator of the Bar and Spiral Structure Legacy Survey (Reid et al. 2016) on the basis of the systemic velocity (Section 2.3) and the sky position of the core. With other lines, the c-C₃H₂ line is basically used for the systemic velocity because the line has the highest detection rate (Section 3.1). Distance and its reference are summarized in Table 1.

The median values of the employed distances are found to be 380 pc for cores in λ Orionis, 430<sup>+0</sup><sub>-40</sub> pc for cores in Orion A, 390<sup>+30</sup><sub>-0</sub> pc for cores in Orion B, 2.3<sup>+7.0</sup><sub>-1.3</sub> kpc for cores in the Galactic plane, and 0.8<sup>+1.8</sup><sub>-0.7</sub> kpc for cores at high latitudes. It is noted that most of the cores in the Galactic plane are distributed farther away than cores at other environments. Orion cores are located at similar distances, but cores at other environments are widely scattered in distance.

## 2.5. Classification of SCUBA-2 Cores into Starless and Protostellar Cores

Each of the 207 SCUBA-2 cores may be either before or after stellar birth, so they need to be classified into two groups: starless cores and protostellar cores. Reliable categorization can be difficult, depending on the availability of protostellar data and references. Therefore, we simply categorize them by visually investigating the existence of a young stellar object (YSO) within the criterion radius centered at the peak position of each core. For example, if no YSO is known within the criterion radius, the core is regarded as a starless core (candidate). If a YSO is located within the criterion radius, we consider the core as a protostellar core (candidate). For simplicity, we refer to starless cores and their candidates as starless cores and to protostellar cores and their candidates as protostellar cores. The criterion radius is adopted from Yi et al. (2018) and Eden et al. (2019). The information of the YSOs is taken from the SIMBAD database, including the past literature and protostar catalogs based on large programs such as Spitzer, WISE, Herschel, and GAIA missions (Megeath et al. 2012; Povich et al. 2013; Dunham et al. 2015; Marton et al. 2016, 2019).

From the visual inspection, the samples of our SCUBA-2 cores are classified into 58 starless cores and 149 protostellar cores. The 58 starless cores consist of 5 cores in λ Orionis, 24 in Orion A, 10 in Orion B, 13 in the Galactic plane, and 6 at high latitudes. Out of 149 protostellar cores, 10, 46, 18, 39, and 36 cores are located in the same five categories of environments, respectively. The classification and the associated YSOs are summarized in Table 1 but may be changed if the YSO information is updated. Considering this uncertainty, among the total 207 SCUBA-2 cores, the upper limit of the fraction of starless cores is found to be ~28%.

## 2.6. Estimation for the Column Density and Column Density Ratio of Molecules

We derive the column densities of the six observed molecules, N<sub>2</sub>D<sup>+</sup>, N<sub>2</sub>H<sup>+</sup>, DNC, HN<sup>13</sup>C, CCS, and HC<sub>3</sub>N (Tables 3 and 4). Among the two transitions of CCS, we use the lower-frequency transition because it has a higher detection rate (Section 3.1). The column densities of the six molecules can be derived with the assumption that the molecular lines are

under local thermodynamic equilibrium as described in Suzuki et al. (1992), Sanhueza et al. (2012), and Mangum & Shirley (2015). For N<sub>2</sub>D<sup>+</sup> and N<sub>2</sub>H<sup>+</sup> lines, the column density is estimated through the HFS fitting as follows: (1) When the HFS fitting is successful to some extent, the column density is estimated from T<sub>ant</sub>τ = (T<sub>ex</sub> − T<sub>bg</sub>)τ as a main factor, together with T<sub>ex</sub> as a weaker contribution. Here, τ and T<sub>bg</sub> are the total line optical depth of all the hyperfine components and the temperature of the cosmic microwave background, respectively. (1–1) If the HFS fitting is fully successful or the T<sub>ant</sub>τ error is ≤50% and excitation temperature is in a range of 4 K ≤ T<sub>ex</sub> ≤ 25 K, the column density is derived from T<sub>ant</sub>τ and T<sub>ex</sub> from the HFS fitting. (1–1–1) In a case of the optically thin limit shown as “τ = 0.1,” τ is too small to constrain. The relative uncertainty in T<sub>ant</sub>τ is small, although that in τ is large. (1–2) If the HFS fitting is partially successful or the error of T<sub>ant</sub>τ is ≤50% but T<sub>ex</sub> is out of the above range, T<sub>ex</sub> is estimated from dust temperature. We assume that gas kinetic temperature (T<sub>k</sub>) is equal to dust temperature, and we also assume T<sub>ex</sub> = 0.5 T<sub>k</sub> following Tatematsu et al. (2017), who studied nine Planck Galactic clumps in the NH<sub>3</sub> lines. (2) When the HFS fitting is not successful or the T<sub>ant</sub>τ error is >50%, the column density is derived through single Gaussian fitting to the brightest hyperfine component of the N<sub>2</sub>D<sup>+</sup> and N<sub>2</sub>H<sup>+</sup> lines. The excitation temperature is, again, estimated from dust temperature. For DNC, HN<sup>13</sup>C, CCS, and HC<sub>3</sub>N lines, the column density is calculated from the peak temperature and line width through the Gaussian fitting, and excitation temperature estimated from dust temperature. We estimate the uncertainty of the column density through propagation from the 1σ fitting error and the rms noise level of the spectrum. Some cores (e.g., G205.46–14.56North1) show excitation anomalies that the ratios of the hyperfine are not fit well with a single excitation temperature (see Figure 4). Note that the Rayleigh–Jeans approximation is assumed in the HFS fitting. Such excitation anomalies are reported by Caselli et al. (1995). We take into account excitation anomalies only as the fitting error in T<sub>ex</sub>. When we employ excitation temperature from dust temperature, we assume that the error in excitation temperature is 50%, following the studies of Tatematsu et al. (2008, 2017). However, even in this case, when T<sub>ex</sub> is too low, we can provide only lower limits on the column density. For instance, if T<sub>ex</sub> is lower than 6.5 K, the line optical depth becomes moderate or large (τ > 0.7) at the lower end of the 50% error range for T<sub>ex</sub>, and we cannot obtain upper limits on the column density reliably. In this case, we show lower limits on the column density obtained at the upper end of the 50% error range for T<sub>ex</sub>. For undetected lines, we derive upper limits on the column density by using the 3σ level at a 0.5 km s<sup>-1</sup> resolution. The column densities of six molecules are listed in Table 5.

For the column density ratios of D/H and N-bearing/ C-chain molecules, we calculate N(N<sub>2</sub>D<sup>+</sup>)/N(N<sub>2</sub>H<sup>+</sup>), N(DNC)/ N(HN<sup>13</sup>C), N(N<sub>2</sub>H<sup>+</sup>)/N(CCS), and N(N<sub>2</sub>H<sup>+</sup>)/N(HC<sub>3</sub>N) under the assumption that these line emissions are emitted from the same region. If one of the pairing column densities is not estimated, the lower limit or the upper limit is shown. The uncertainty of the column density ratio is given by propagating from the error of column density in the ratio. Table 5 lists the column density ratios.

Note. All values are measured in a spectrum whose peak temperature is higher than $3\sigma$. In the case of a peak temperature below $3\sigma$, the $3\sigma$ level is listed as an upper limit. Column (1): SCUBA-2 core name. Columns (2)–(4): peak temperature at the $T_A^*$ scale, systemic velocity, and FWHM inferred by Gaussian fitting to the spectrum of the 82 GHz CCS line, respectively. Columns (5)–(7): same as Columns (2)–(4), but for the 94 GHz CCS line. Columns (8)–(10): same as Columns (2)–(4), but for HC<sub>3</sub>N. Columns (11)–(13): peak temperature at the $T_A^*$ scale, systemic velocity, and FWHM inferred by Gaussian fitting to the brightest hyperfine component of the N<sub>2</sub>H<sup>+</sup> line, respectively. Columns (14)–(18): systemic velocity, FWHM, excitation temperature ($T_{ex}$), total line optical depth of all the hyperfine components ($\tau$), and $T_{ant}\tau = (T_{ex} - T_{bg})\tau$ estimated through the hyperfine structure fitting to seven components of the N<sub>2</sub>H<sup>+</sup> line, respectively. In Columns (16) and (17), “†” indicates that the value is derived from dust temperature.

Note. All values are measured in a spectrum whose peak temperature is higher than 3σ. In the case of a peak temperature below 3σ, the 3σ level is listed as an upper limit. Column (1): SCUBA-2 core name. Columns (2)–(4): peak temperature at the $T_A^*$ scale, systemic velocity, and FWHM inferred by Gaussian fitting to the spectrum of the c-C<sub>3</sub>H<sub>2</sub> line, respectively. Columns (5)–(7): same as Columns (2)–(4), but for DNC. Columns (8)–(10): same as Columns (2)–(4), but for HN<sup>13</sup>C. Columns (11)–(13): peak temperature at the $T_A^*$ scale, systemic velocity, and FWHM inferred by Gaussian fitting to the brightest hyperfine component of the N<sub>2</sub>D<sup>+</sup> line, respectively. Columns (14)–(18): systemic velocity, FWHM, excitation temperature ($T_{ex}$), total line optical depth of all the hyperfine components ($τ$), and $T_{ant}τ$ ($=(T_{ex} - T_{bg})τ$) estimated through the hyperfine structure fitting to seven components of the N<sub>2</sub>D<sup>+</sup> line, respectively. In Columns (16) and (17), “†” indicates that the value is derived from dust temperature.
## 2.7. Mach Number Estimate

We calculate the Mach number $M = \sigma_{NT}/c_s$ to measure the contribution of turbulence in the stability of the dense core. This parameter is used to judge whether a dense core is subsonic ($M \le 1$), transonic ($1 < M \le 2$), or supersonic ($M > 2$). The nonthermal velocity dispersion ($\sigma_{NT}$) is derived in the following form (e.g., Myers 1983; Fuller & Myers 1992; Caselli et al. 2002a):

$$ \sigma_{NT} = \sqrt{\frac{\Delta v^2}{8 \ln 2} - \frac{k_B T_k}{m}}, \quad (1) $$

where $k_B$ is the Boltzmann constant and $T_k$ is the kinetic temperature. $\Delta v$ and $m$ are the line width (FWHM) and mass of the observed molecule, respectively. The sound speed ($c_s$) is estimated by $\sqrt{k_B T_k/m}$ for the H$_2$ molecule.

We assume that $T_k$ is equal to dust temperature. For $\Delta v$ and $m$, we adopt the N$_2$H$^+$ molecule because it traces the dense gas. The uncertainty of the Mach number is derived by propagating from the error of the fitting, the error of dust temperature, and the rms ($\sigma$) noise level of the spectrum. The Mach number is listed in Table 5.

# 3. Results

## 3.1. Detection Rate of Molecular Emission Lines

Table 6 summarizes the detection rates of eight molecular lines in SCUBA-2 cores in different environments. Regarding the detection rates of c-C$_3$H$_2$, DNC, HN$^{13}$C, and N$_2$D$^+$ lines observed toward all SCUBA-2 cores, it is found that the detection rates of all lines are higher than 49%. In particular, the c-C$_3$H$_2$ (late-type in the cloud chemistry) line shows the highest detection rate (91%) and is detected in almost all cores at high latitudes. The HN$^{13}$C line is also detected at the highest rate in cores at high latitudes. The deuterated molecular lines DNC and N$_2$D$^+$ are detected at the highest rate in cores in Orion B and at high latitudes, respectively. All four lines tend to be more detected in protostellar cores than in starless cores.

Regarding the detection rates of CCS-L/H, HC$_3$N, and N$_2$H$^+$ lines that were only observed toward cores in $\lambda$ Orionis, Orion A, and Orion B, it is found that, generally speaking, the N$_2$H$^+$ (late-type molecule) and HC$_3$N lines show high detection rates ($\ge 47\%$), whereas CCS lines, which trace the early phase in the cloud chemistry, show low detection rates ($\le 26\%$). Among the three environments, all four lines are detected the highest in cores in Orion A, and the CCS-L, HC$_3$N, and N$_2$H$^+$ lines tend to be more detected in protostellar cores than in starless cores, whereas the CCS-H line tends to be more detected in starless cores than in protostellar cores.

In summary, both the low detection rate of early-type molecular lines and the high detection rate of late-type molecular lines and deuterated molecular lines suggest that most of the SCUBA-2 cores are chemically evolved.

## 3.2. Beam Dilution Effect on Distant SCUBA-2 Cores

Among the four column density ratios estimated in Section 2.6, the column density ratio of DNC/HN$^{13}$C is available for cores in all environments, but the three other column density ratios, including N$_2$H$^+$ molecules, are available only for cores in $\lambda$ Orionis, Orion A, and Orion B. To estimate the column density ratio, we assume that the beam filling factor is the same for both the emission lines. However, because the

SCUBA-2 cores are located at very different distances ranging from ~0.1 kpc to ~10 kpc, our telescope observes them with very different linear beam sizes. Figure 5(a) shows the integrated intensity ratio of DNC/HN$^{13}$C against the linear beam size in pc. The ratio does not increase or decrease significantly for a beam size of <0.1 pc but decreases with increasing beam size for >0.1 pc with a power-law index of -1. Because dense cores have a typical size of 0.1 pc, distant cores observed with larger beam size can be affected by different beam dilution between the two lines; DNC is beam diluted, while beam dilution for HN$^{13}$C is much weaker. In other words, larger linear beams for distant cores tend to involve the outer, less dense region having low deuterium fraction. A linear beam size of 19'' corresponds to 0.1 pc at a distance of 1.1 kpc. This differential beam dilution can lead to misinterpretations in the chemical properties of SCUBA-2 cores at different distances. We investigate whether it is the case for the column density ratio of DNC/HN$^{13}$C and DNC/HNC. In Figures 5(b) and (c), we plot the column density ratio against distance. The column density ratio of DNC/HNC is derived by using the abundance ratio formula of $^{12}$C/$^{13}$C as a function of Galactocentric distance obtained by Savage et al. (2002). Panels (b) and (c) of Figure 5 show similar trends that both the column density ratios decrease with increasing distance for distant cores (>1 kpc). It seems that the column density ratio is seriously affected by differential beam dilution between the two lines for distant cores (distance >1 kpc). Therefore, with our beam size, the column density ratio seems reliable if distance is <1 kpc.

The percentage of protostellar cores (65%) in the Orion region (distance ~400 pc) is smaller than that of cores with distances of 2–10 kpc in the Galactic plane (81%). It is possible that the protostellar core percentage increases with increasing distance. It is likely that the YSO sensitivity is shallower for distant cores. Furthermore, the beam dilution may merge weaker starless cores into brighter protostellar cores. In the Orion region, starless cores are half as intense as protostellar cores in the SCUBA-2 flux density. Figure 10 of Eden et al. (2019) shows that the percentage of the SCUBA-2 core detection decreases with increasing distance, which may suggest that the SCUBA-2 sensitivity becomes insufficient for weaker cores at larger distances.
