**Note.** “CCS-L” and “CCS-H” represent the low and high transitions of the CCS line, respectively. The numbers in parentheses indicate the total number of cores. The numbers represent the number of dense cores detected in the molecular line in percentages. All detection rates are inferred for sources whose peak temperature is higher than 3σ. There are no available data of CCS, HC<sub>3</sub>N, and N<sub>2</sub>H<sup>+</sup> lines for cores at other environments except for the Orion region.

To avoid distance-related issues, we start with the properties of cores in the three subregions of the Orion region with similar distances.

### 3.3. Column Density Ratios of N<sub>2</sub>D<sup>+</sup>/N<sub>2</sub>H<sup>+</sup>, DNC/HN<sup>13</sup>C, N<sub>2</sub>H<sup>+</sup>/CCS, and N<sub>2</sub>H<sup>+</sup>/HC<sub>3</sub>N for SCUBA-2 Cores in λ Orionis, Orion A, and Orion B

Figure 6 plots the column density ratios of N<sub>2</sub>D<sup>+</sup>/N<sub>2</sub>H<sup>+</sup>, N<sub>2</sub>H<sup>+</sup>/CCS, and N<sub>2</sub>H<sup>+</sup>/HC<sub>3</sub>N against that of DNC/HN<sup>13</sup>C for starless/protostellar cores in λ Orionis, Orion A, and Orion B. Table 7 summarizes the statistics of the column density ratios. We consider only cores where both column densities are successfully estimated.

For the four column density ratios, there is no systematic difference between starless and protostellar cores in λ Orionis, Orion A, and Orion B. This may indicate that cores in these three regions have similar chemical properties as a whole.

We examine the correlations between the four column density ratios using the correlation coefficient (C.C) derived by the Pearson product-moment correlation coefficient. This method estimates the strength of the relationship between the relative movements of two variables and provides a value between -1.0 and +1.0. The values of +1.0 and -1.0 indicate a strong positive and negative correlation, respectively, and the value of 0 represents no correlation. The C.C. considers only cores of 7 or more in the number of samples where both column densities in the ratio are

successfully calculated, but it does not take into account outliers in the sample. For N(N<sub>2</sub>D<sup>+</sup>)/N(N<sub>2</sub>H<sup>+</sup>) and N(DNC)/N(HN<sup>13</sup>C), cores in Orion A show a positive correlation. This result suggests that N(N<sub>2</sub>D<sup>+</sup>)/N(N<sub>2</sub>H<sup>+</sup>) and N(DNC)/N(HN<sup>13</sup>C) seem effective for SCUBA-2 cores as chemical evolution tracers.

YSOs inside star-forming cores will have shocks and radiation and make the chemistry of protostellar cores more complex. In this paper, we defer our discussion on protostellar cores to our future papers and concentrate on the characteristics of starless cores.

## 3.4. Column Density Ratio against H<sub>2</sub> Column Density and Dust Temperature

The H<sub>2</sub> column density and dust temperature in the central region of the core can be used as the indicator of core evolution because the density increases and the temperature decreases throughout the starless core evolution (Shirley et al. 2005;

Aikawa et al. 2008). We investigate whether D/H has any correlation with the dust temperature and H<sub>2</sub> column density for local (<1 kpc) starless cores in different environments using the correlation coefficient. Figure 7 shows the column density ratio of DNC/HN<sup>13</sup>C and N<sub>2</sub>D<sup>+</sup>/N<sub>2</sub>H<sup>+</sup> against the dust temperature and H<sub>2</sub> column density. Cores in the Galactic plane are excluded because all of the cores are more distant than 1 kpc.

For D/H against the dust temperature and against the H<sub>2</sub> column density, there seems to be no apparent correlation. This is likely due to the fact that the spatial resolution of the Planck telescope (5' corresponds to ~0.5 pc at a distance of ~400 pc) is too low to trace the variation of temperature or density. Figure 8 plots the H<sub>2</sub> column density as a function of dust temperature for local starless cores in different environments and shows no clear correlation between the two quantities. No clear trend is seen, probably because the resolution is too low.

### 3.5. Variation of D/H, Dust Temperature, and H<sub>2</sub> Column Density against Declination for Starless Cores in λ Orionis, Orion A, and Orion B

In the Orion region, shell/ring-shaped structure λ Orionis and filamentary clouds Orion A and B are extensively distributed along the declination, as shown in Figure 2. For starless cores in λ Orionis, Orion A, and Orion B, we examine whether there is any variation in dust temperature, H<sub>2</sub> column density, and D/H along the declination Figure 9 shows the spatial distribution, dust temperature, H<sub>2</sub> column density, N(N<sub>2</sub>D<sup>+</sup>)/N(N<sub>2</sub>H<sup>+</sup>), and N(DNC)/N(HN<sup>13</sup>C) with respect to declination. Along the declination, the dust temperature and H<sub>2</sub> column density appear to increase toward a declination of ~-4° to -3°. We exclude cores with a declination from -5° 50' to -5° strongly externally heated by the Orion Nebula. Although we see slight increase in the dust temperature and H<sub>2</sub> column density near the Orion Nebula, we do not see any systematic trend in the D/H fraction.

### 3.6. Comparison of Deuterium Fraction between Starless Cores and Other Cores

We compare the deuterium fraction between starless cores and other cores reported in previous studies. The average N(N<sub>2</sub>D<sup>+</sup>)/N(N<sub>2</sub>H<sup>+</sup>) of starless cores in the Orion region (0.2 ± 0.1) is found to be lower than that of PGCCs (0.5) reported in Tatematsu et al. (2017), which is similar to that of low-mass starless cores (0.1, Crapsi et al. 2005) and higher than that of massive protostellar IRAS cores (0.01, Fontani et al. 2006). If we assume ¹²C/¹³C = 52 (Savage et al. 2002), the average N(DNC)/N(HNC) of starless cores in the Orion region (0.08 ± 0.03) seems to be similar to those of 13 PGCCs (0.08) found in Tatematsu et al. (2017) and protostellar cores in the Perseus molecular cloud (0.06) in Imai et al. (2018), but higher than that of low-mass starless cores (0.02) in Hirota & Yamamoto (2006). Approximately 30% of the starless cores in the Orion region are found to have an N(DNC)/N(HNC) higher

than the value of 0.05 for L1544 (Hirota et al. 2003; Hirota & Yamamoto 2006), suggesting that they could be starless cores more evolved toward the beginning of star formation.

# 4. Discussion

## 4.1. Identification of the Dense Cores on the Verge of Star Formation in the Orion Region Using CEFs

The CEF is expressed in the form of $CEF = \log([N(A)/N(B)]/[N_0(A)/N_0(B)]) \times d$ for molecules A and B. $N(A)/N(B)$ is the ratio of column densities inferred from observations, and $N_0(A)/N_0(B)$ is the ratio of column densities at the onset of star formation. The factor $d$ is defined so that all cores range from ~−100 for starless cores to ~+100 for star-forming cores through 0 for cores on the verge of star formation. In this paper,

we derive the CEF for only starless cores to identify late starless cores using $N(N_2D^+)/N(N_2H^+)$ and $N(DNC)/N(HN^{13}C)$. For starless cores, $N_0(A)/N_0(B)$ approximately corresponds to the maximum of the column density ratio of D/H molecules, and $d$ is determined for all starless cores so that the CEF ranges from ~−100 to ~0. Using two column density ratios listed in Table 5, we determine $N_0(A)/N_0(B)$ and $d$. We consider only starless cores in the Orion region because they should be located at similar distances. Out of them, we consider only cores in which both column densities in the ratio are successfully estimated. We exclude cores externally affected by large-scale star-forming activities (e.g., Orion Nebula; see Figure 9). For the 16 starless cores in the Orion region for which column density ratios are successfully obtained, we first derive the CEF values using the definition
<figure><img src="image_24.png" /><figcaption>Figure 10. CEF for starless cores in the Orion region and for local (<1 kpc) starless cores studied in Tatematsu et al. (2017) in ascending numeric order of the average CEF. The top and bottom panels show CEF1.0 derived by the equations in Tatematsu et al. (2017) and CEF2.0 by our study, respectively.

of Tatematsu et al. (2017), which we call CEF1.0. The top panel of Figure 10 shows the CEF1.0 values of the Orion cores. We also plot local (<1 kpc) cores studied in Tatematsu et al. (2017). CEF1.0 ranges from ~-75 to ~50, which is different from the original definition of the CEF. For example, L1544, known as a gravitational collapsing prestellar core (Tafalla et al. 1998), has a CEF1.0 close to zero, which is reasonable. However, half of the starless Orion cores have positive CEF1.0, suggesting that CEF1.0 of Tatematsu et al. (2017) needs to be updated.

Using both samples of our starless Orion cores and the local cores from Tatematsu et al. (2017), we determine new CEF2.0 equations in the following forms:

$$ \text{CEF2.0}(\text{N}_2\text{D}^+) = \log\left(\frac{N(\text{N}_2\text{D}^+)/N(\text{N}_2\text{H}^+)}{0.56}\right) \times 59, \quad (2) $$

$$ \text{CEF2.0}(\text{DNC}) = \log\left(\frac{N(\text{DNC})/N(\text{HN}^{13}\text{C})}{9.3}\right) \times 87. \quad (3) $$

We search for $N_0(A)/N_0(B)$ and $d$ for CEF2.0($N_2D^+$) and CEF2.0(DNC) that minimizes the rms of CEF2.0($N_2D^+$)–CEF2.0(DNC) while satisfying a condition that the minimum

CEF2.0(average) is -100 and the maximum CEF2.0(average) is 0 for the starless cores. The reason for finding $N_0(A)/N_0(B)$ and $d$ in this manner is to illustrate chemical evolution as simple as possible because different pairs of molecules may show different characteristics. The uncertainty of the CEF is estimated through propagation from the error of the column density ratio. The derived CEF2.0 is shown in the bottom panel of Figure 10, and values for the starless Orion cores are listed in Table 8.

The CEF1.0 of Tatematsu et al. (2017) was constructed on the basis of 15 nearby low-mass starless cores with kinetic temperatures of 10–20 K observed at spatial resolutions of 0.015–0.05 pc. In the present study, the CEF2.0 is constructed by adding the data of the 16 starless GMC cores in the Orion region to the existing samples having similar ranges of temperature and spatial resolution. Part of the origin of differences between the two CEF versions is probably due to the different range of evolutionary stages. For instance, Tatematsu et al. (2017) used cores of a broad range of different environments, while the present study investigates one region where environmental differences may be smaller. Indeed, the

detection rate of CCS is low in the Orion cores (Section 3.1), suggesting that they are chemically evolved. Furthermore, we used SCUBA-2 cores for observations, which are possibly biased to evolved cores having steeper radial intensity distribution. It is likely that these facts make the CEF2.0 values of starless Orion cores closer to zero. Probably our new CEF2.0 can be used more reliably if the telescope beam size is ≲0.1 pc.

The bottom panel of Figure 10 shows the CEF2.0 of the 16 starless cores in the Orion region and the samples of Tatematsu et al. (2017) aligned in ascending numeric order of the CEF2.0. For the starless Orion cores, the CEF2.0 ranges from ~-60 (G209.77–19.40East3) to ~0 (G210.37–19.53North). Compared to the CEF2.0 for L1544, we judge that at least eight starless cores have CEF2.0 close to zero (≥-33), suggesting that they are late starless cores on the verge of star formation. Figure 11 shows their spatial distribution on the Planck 850 µm dust continuum map. They are mostly located in the south of Orion KL, at decl. (J2000) = -7°.2 to -5°.9. We suggest that these cores are good targets for studying the initial conditions of star formation. G211.16–19.33North3, one of these starless cores having CEF2.0 close to zero, and the star-forming Orion core G210.82–19.47North1, having bright N<sub>2</sub>D<sup>+</sup> emission, were recently observed by Tatematsu et al. (2020) with the ALMA ACA interferometer.

Regarding the number of the starless cores with successful CEF2.0 estimation, the Orion A subregion has the largest number. The percentages of the starless cores with successful CEF2.0 estimation are 43% and 40% for Orion A and B, respectively, which are very similar. λ Orionis has no core with successful CEF2.0, which is natural because the number of SCUBA-2 cores is small. We see no difference among the Orion subregions in terms of the success rate of CEF2.0 estimation.

Red and blue represent starless cores with average CEF2.0 of <-33 and ≥-33, respectively.</figcaption></figure>

We investigate whether there is any variation in the physical properties of starless cores when the average CEF approaches zero. Figure 12 shows the diagrams for H<sub>2</sub> column density, dust temperature, and Mach number as a function of the average CEF2.0. We simply compare the mean values of the physical properties for two groups separated by an average CEF2.0 of -33: early starless phase (CEF2.0 < -33) and late starless phase (-33 ≤ CEF2.0). When starless cores evolve, three physical properties do not seem to increase or decrease significantly. The lack of trends in the H<sub>2</sub> column density and dust temperature appears to be inconsistent with the prediction of the core evolution model (e.g., Shirley et al. 2005; Aikawa et al. 2008). These discrepancies may be due to the reasons discussed in Section 3.4. The lack of a trend in the Mach number may suggest that the turbulence dissipation in
the dense region of starless core is not required for the onset of star formation, because turbulent dissipation is regarded as one possibility to change a stable core to an unstable one (e.g., Nakano 1998). Other mechanisms may be required to change stable cores to unstable ones (e.g., accretion flow of gas; Gómez et al. 2007). Indeed, in G211.16-19.33 North3, Tatematsu et al. (2020) obtained a hint of gas accretion onto one subcore inside, with the ALMA ACA interferometer. However, we cannot rule out the possibility of turbulence dissipation for the beginning of star formation completely because the angular resolution of our telescope may be insufficient, and systematic observations with higher angular resolution are needed.

## 4.2. Identification of Candidates for Late Starless Cores in Environments Other Than the Orion Region

For most of the starless cores in environments other than the Orion region, it is difficult to establish the CEF2.0 because of largely different linear beam sizes (Section 3.2). Moreover, only $N(\text{DNC})/N(\text{HN}^{13}\text{C})$ is available for these environments. Taking this into account, we look for late starless core candidates with both high $N(\text{DNC})/N(\text{HN}^{13}\text{C})$ and $N_2\text{D}^+$ detection among local (<1 kpc) starless cores in two environments. All starless cores in the Galactic plane are more distant than 1 kpc. Two cores (SCOPEG001.37+20.95, SCOPEG202.32+02.53) at high latitudes are found to have high $N(\text{DNC})/N(\text{HN}^{13}\text{C})$ and detection in $N_2\text{D}^+$ line. Among these cores, the highest $N(\text{DNC})/N(\text{HN}^{13}\text{C})$ is found in SCOPEG001.37+20.95 (14.6).

# 5. Summary

We conducted a molecular line survey of 207 SCUBA-2 cores embedded in the PGCCs with the Nobeyama 45 m telescope in the $N_2\text{D}^+ J = 1-0$, $N_2\text{H}^+ J = 1-0$, DNC $J = 1-0$, $\text{HN}^{13}\text{C} J = 1-0$, CCS $J_N = 7_6-6_5$, CCS $J_N = 8_7-7_6$, HC$_3$N $J = 9-8$, and c-C$_3$H$_2$ $J_{K_a K_b} = 2_{12} - 1_{01}$ lines to identify dense cores on the verge of star formation in five different environments ($\lambda$ Orionis, Orion A, Orion B, the Galactic plane, and high latitudes). The main results are summarized as follows:

1. A total of 207 SCUBA-2 cores are classified into 58 starless cores (candidates) and 149 protostellar cores (candidates). They consist of 5 starless cores and 10 protostellar cores in $\lambda$ Orionis, 24 and 46 in Orion A, 10 and 18 in Orion B, 13 and 39 in the Galactic plane, and 6 and 36 at high latitudes. Among the total 207 SCUBA-2 cores, starless cores occupy ~28%.

2. The detection rates of early-type molecules (CCS) are low and the detection rates of late-type molecules (c-C$_3$H$_2$, $N_2\text{H}^+$) and the deuterated molecules (DNC, $N_2\text{D}^+$) are high, suggesting that most of the SCUBA-2 cores are chemically evolved.

3. The integrated intensity ratio and column density ratio of DNC to $\text{HN}^{13}\text{C}$ (HNC) tend to decrease with increasing distance (>1 kpc correspond to linear beam sizes of >0.1 pc). This suggests that the deuterium fraction suffers from differential beam dilution between the two lines for distant cores (>1 kpc).

4. For starless and protostellar cores in $\lambda$ Orionis, Orion A, and Orion B, the column density ratios of $N_2\text{D}^+/N_2\text{H}^+$, DNC/$\text{HN}^{13}\text{C}$, $N_2\text{H}^+/\text{CCS}$, and $N_2\text{H}^+/\text{HC}_3\text{N}$ are similar. This suggests that cores in these three regions have

similar chemical properties. Between four column density ratios, $N(\text{DNC})/N(\text{HN}^{13}\text{C})$ and $N(\text{N}_2\text{D}^+)/N(\text{N}_2\text{H}^+)$ have a positive correlation, suggesting that the two ratios could act as better tracers for core chemical evolution.

5. In the Orion region, at least eight starless cores are identified as dense cores on the verge of star formation using the chemical evolution factor built on the basis of $N(\text{N}_2\text{D}^+)/N(\text{N}_2\text{H}^+)$ and $N(\text{DNC})/N(\text{HN}^{13}\text{C})$. At high latitudes, at least two starless cores are identified to be close to the beginning of star formation on the basis of high $N(\text{DNC})/N(\text{HN}^{13}\text{C})$ and $N_2\text{D}^+$ line detection. For starless cores in the Orion region, when starless cores evolve, the Mach number does not increase or decrease, which may indicate that the dissipation of turbulence in the dense region of the cores may not be an important mechanism for the onset of star formation as judged from observations with a beam size of 0.04 pc.

SCUBA-2 cores associated with high/low-mass star-forming regions from the Galactic plane to high latitudes are located at highly different distances. For the study of the properties of dense cores at the constant spatial resolution with a single telescope, we need a set of observations to circumvent the beam dilution effect. In addition, for starless cores close to the onset of star formation found in this study, mapping observations are necessary to investigate whether they are gravitationally bound.
