## Abstract

While monitoring a sample of apparently slowly rotating superficially normal early-A stars, we have discovered that HR 8844 (A0 V) is actually a new chemically peculiar star. We first compared the high-resolution spectrum of HR 8844 with that of four slow rotators near A0V ($\nu$ Cap, $\nu$ Cnc, Sirius A, and HD 72660) to highlight similarities and differences. The lines of Ti II, Cr II, Sr II, and Ba II are conspicuous features in the high-resolution high signal-to-noise SOPHIE spectra of HR 8844 and much stronger than in the spectra of the normal star $\nu$ Cap. The Hg II line at 3983.93 Å is also present in a 3.5% blend. Selected unblended lines of 31 chemical elements from He up to Hg have been synthesized using model atmospheres computed with ATLAS9 and the spectrum synthesis code SYNSPEC48 including hyperfine structure of various isotopes when relevant. These synthetic spectra have been adjusted to the mean SOPHIE spectrum of HR 8844, and high-resolution spectra of the comparison stars. Chisquares were minimized to derive abundances or upper limits to the abundances of these elements for HR 8844 and the comparison stars. HR 8844 is found to have underabundances of He, C, O, Mg, Ca, and Sc, mild enhancements of Ti, V, Cr, Mn, and distinct enhancements of the heavy elements Sr, Y, Zr, Ba, La, Pr, Sm, Eu, and Hg, the overabundances increasing steadily with atomic number. This chemical pattern suggests that HR 8844 may actually be a new transition object between the coolest HgMn stars and the Am stars.

**Key words:** stars: abundances – stars: chemically peculiar – stars: early-type – stars: individual (HR 8844)

## 1. Introduction

A bibliographic query of the CDS for HR 8844 actually reveals only 34 publications. HR 8844 appears in Cowley et al. (1969)'s classification of the bright A stars and was ascribed an A0V spectral type by these authors. They did not comment on any peculiarity of the spectrum. HR 8844 is also in Eggen's survey of A0 stars (Eggen 1984); it appears as a single star in Eggleton & Tokovinin (2008). The purpose of this paper is to perform a detailed abundance analysis of HR 8844 and show that this star is a new chemically peculiar (CP) star.

We have recently undertaken a spectroscopic survey of all apparently slowly rotating bright early-A stars (A0-A1V) and late-B stars (B8-B9V) observable from the northern hemisphere. This project addresses fundamental questions of the physics of late-B and early-A stars: (i) can we find new instances of rapid rotators seen pole-on (other than Vega) and study their physical properties (gradient of temperature across the disk, limb and gravity darkening) and (ii) is our census of CP stars complete up to the magnitude limits we adopted? If not, what are the physical properties of the newly found CP stars? The abundance results for the A0-A1V sample have been published in Royer et al. (2014). Targets have been observed with SOPHIE, the échelle high-resolution spectrograph at Observatoire de Haute Provence yielding spectra covering the 3900–6800 Å spectral range over 39 orders at a resolving power $R = 75,000$. A careful abundance analysis of the high-resolution high signal-to-noise ratio (S/N) spectra of the A stars sample and a hierarchical classification have allowed to sort out the sample of 47 A stars into 17 chemically normal stars (i.e., those whose abundances do not depart by more than $\pm 0.20$ dex

from solar values), 12 spectroscopic binaries, and 13 CP stars among which five are new CP stars. The status of these new CP stars still needs to be fully specified by spectropolarimetric observations to address their magnetic nature or by exploring new spectral ranges which we had not explored in this first study.

We now started to examine the B8-B9V sample using the full wavelength coverage provided by SOPHIE to search for new CP stars. We have already reported on the discovery of four new HgMn stars (Monier et al. 2015), whose spectra display strong Hg II lines at 3984 Å and strong Mn II lines. In the process of our analysis of the B8-B9V sample, we also found that HD 67044 is most likely another new HgMn star (Monier et al. 2016).

Royer et al. (2014) performed abundance analyses for C, O, Mg, Si, Ca, Sc, Ti, Cr, Fe, Sr, Y, and Zr using Takeda's automated procedure and classified HR 8844 as "probably normal": the four criteria used for the automatic classification were not fully consistent, depending on the chemical species used. To clarify the nature of HR 8844, we have compared its spectra with high-resolution high S/N spectra of four stars near A0V and B9V: the superficially normal $\nu$ Cap (B9V), the cool HgMn star $\nu$ Cnc, Sirius A (A1m), and HD 72660 (A1m). We then determined the abundances of 31 chemical elements, in particular helium and several species heavier than barium (not studied in Royer et al. 2014), for HR 8844 using spectrum synthesis to quantify the enhancements and depletions of these elements or to provide upper limits. We also performed the abundance analysis for the four comparison stars using as much as feasible the same lines and atomic data as employed for HR 8844 for consistency to compare the chemical composition of

## 2. Observations and Reduction

We obtained one spectrum of HR 8844 on 2009 August 5 and then secured three new spectra in 2016 December at Observatoire de Haute Provence using the high-resolution ($R=75,000$) mode of the SOPHIE échelle spectrograph (Perruchot et al. 2008). The S/N ratio of the individual spectra ranges from 251 up to 381 at 5500 Å. For $\nu$ Cap, we secured four high-resolution spectra with HERMES (Raskin et al. 2011) at the Roque de los Muchachos Observatory. For the three other comparison stars, we fetched spectra from spectroscopic archives. For HD 72660, we fetched a spectrum from the HARPS archive ($R=125,000$) and for Sirius A several I profiles obtained with NARVAL from the Polarbase database ($R=75,000$). For $\nu$ Cnc, we retrieved a spectrum from the ELODIE archive ($R=45,000$). The observations log of these data for the 5 stars is displayed in Table 1.

The SOPHIE, ELODIE, HARPS, NARVAL, and HERMES data are automatically reduced by the individual projects to produce 1D extracted and wavelength calibrated échelle orders. Each reduced order was normalized separately using a Chebychev polynomial fit with sigma clipping, rejecting points above or below $1\sigma$ of the local continuum. Normalized orders were then merged together, corrected by the blaze function and resampled into a constant wavelength step of about 0.02 Å (see Royer et al. 2014, for more details). The radial velocity of HR 8844, $\nu$ Cap, and HD 72660 were derived in Royer et al. (2014) using cross-correlation techniques, avoiding the Balmer lines

and the atmospheric telluric lines. The normalized spectrum was cross-correlated with a synthetic template extracted from the POLLUX database<fnref n="6" /> (Palacios et al. 2010) corresponding to the parameters $T_{eff}=11,000$ K, $log g=4$ and solar abundances. A parabolic fit of the upper part of the resulting cross-correlation function yields the Doppler shift, which is then used to shift spectra to rest wavelengths. The projected rotational velocities are taken from Royer et al. (2014) who derived them from the position of the first zero of the Fourier transform of individual lines. The radial velocity and projected equatorial velocity of HR 8844, $\nu$ Cap, HD 72660, $\nu$ Cap, and $\nu$ Cnc are collected in Table 2. For Sirius A, they were retrieved from Landstreet (2011).

## 3. The Line Spectrum of HR 8844—Comparison to $\nu$ Cap

### 3.1. The Line Spectrum of HR 8844

To establish the chemical peculiarity of HR 8844, we measured the centroids of all 552 lines absorbing more than 2% of the continuum. Almost all these lines could be identified after we performed a complete synthesis of the spectrum and derived the abundances. The proposed identifications corresponding to the final abundances of HR 8844 are collected in Table 3. The strongest lines (i.e., which absorb more than 5% of the continuum) are due to Mg II, Mg I, Ca II (resonance lines), Ca I (idem), Ti II, Cr II, Fe II, Fe I, Sr II, and Ba II. Several spectral regions have been inspected to search for the chemical peculiarity of HR 8844. First, the red wing of $H\epsilon$, harbors a line close to the location of the Hg II $\lambda$ 3983.93 Å line and several Zr II and Y II lines

likely to be strengthened in CP stars. After proper correction for the stellar radial velocity, we found that HR 8844 does show a feature next to the Hg II 3983.93 Å line absorbing about 3.5%, and also the lines of Y II at 3982.59 Å (2%) and of Zr II at 3991.13 Å (3.5%) and 3998.97 Å (2%). Several other lines of Y II and Zr II could be identified in the spectrum of HR 8844, and have been used to derive the abundances of these elements. Second, we examined the region from 4125 Å to 4145 Å for the Si II lines at 4128.054 Å and 4130.894 Å and the Mn II line at 4136.92 Å. This Mn II line is definitely present in HR 8844 but is only a weak line (0.5%). Similarly, the lines of Mn II at 4206.37 Å and 4252.96 Å absorb respectively 1.5% and 2.0%. The abundance analysis of two Mn II lines with hyperfine structure will reveal a manganese excess of about two times the solar value.

## 3.2. Comparison with Spectra of ν Cap

HR 8844, Vega, and ν Cap have similar effective temperatures, surface gravities, and projected equatorial velocities $v_c \sin i$. Differences in the line intensities should therefore reflect mostly differences in chemical compositions. Several spectral regions highlight the differences between HR 8844 and ν Cap. Several lines are stronger in HR 8844 than in ν Cap and Vega which shows than HR 8844 is enriched in the elements responsible for these lines with respect to ν Cap and Vega. We will only show the comparisons with ν Cap here. Figure 1 displays the comparison of the spectra of ν Cap and HR 8844 in the range from 4930 to 4940 Å where three lines of C I and the resonance line of Ba II at 4934.096 Å fall. All lines of C I are slightly stronger and the Ba II line is much stronger in HR 8844. Figure 2 displays the comparison of the spectra of ν Cap and HR 8844 in the range 6140 to 6160 Å where several lines of O I fall together with the Fe II lines at 6147.62 Å and 6149.26 Å and the Ba II line at 6141.713 Å. All O I lines are weaker in HR 8844, whereas the Ba II line is much stronger in HR 8844. Figure 3 displays the comparison of the spectra of

ν Cap and HR 8844 in the range 4300 to 4320 Å where 4 Ti II lines, the Sc II line at 4314.18 Å, and the Sr II line at 4305.443 Å fall. The lines of Ti II, Sc II, and Sr II are all stronger in the spectrum of HR 8844 than in that of ν Cap. Figure 4 displays the comparison of the spectra of ν Cap and HR 8844 in the range 4060 Å up to 4080 Å where the Ni II at 4067.04 Å and the Sr II resonance line at 4077.70 Å fall. These two lines are stronger in the spectrum of HR 8844 than in that of ν Cap. Finally, Figure 5 displays the comparison of the SOPHIE spectra of ν Cap and HR 8844 in the range 4260 up to 4280 Å where the C II doublet at 4267.00 Å and 4267.26 Å and the Cr II lines at 4261.92 Å and 4275.56 Å fall. The C II lines are weaker in HR 8844 than in ν Cap and the Cr II lines are slightly stronger in HR 8844. From these first comparisons, we infer that C, O should be less abundant in HR 8844 than in ν Cap, whereas Fe may be comparable and Ti, Cr, Ni, Sr, and Ba are more abundant in HR 8844 than in ν Cap. Similar trends are found when comparing the spectra of Vega and HR 8844. The abundance analysis carried out in next paragraph will confirm this.

# 4. Abundance Determinations for HR 8844, ν Cap, ν Cnc, Sirius A, and HD 72660

## 4.1. Fundamental Parameters Determinations

For HR 8844, ν Cap, and ν Cnc, we applied Napiwotzky's (Napiwotzki et al. 1993) UVBYBETA procedure to derive the effective temperature and surface gravity. The fundamental parameters of Sirius A and HD 72660 were taken, respectively, from Landstreet (2011) and Golriz & Landstreet (2016). The adopted effective temperatures, surface gravities, projected equatorial velocities, and radial velocities for HR 8844, Vega, ν Cap, ν Cnc, Sirius A, and HD 72660 are collected in Table 2. The adopted values for the parameters of HR 8844 are in good agreement with the spectroscopic determination of Gebran et al. (2016). The projected equatorial velocities and radial velocities of HR 8844 and

## 4.2. Microturbulent Velocity Determination

To derive the microturbulent velocity of HR 8844, Vega, *ν* Cap, *ν* Cnc, Sirius A, and HD 72660, we simultaneously

derived the iron abundance [Fe/H] for 50 unblended Fe II lines and a set of microturbulent velocities ranging from 0.0 to 5.0 km s⁻¹. Figure 6 shows the standard deviation of the derived [Fe/H] as a function of the microturbulent velocity. The adopted microturbulent velocities are the values which minimize the standard deviations i.e., for that value, all Fe II lines yield the same iron abundance. We therefore adopt a

microturbulent velocity $\xi_t = 1.4 \pm 0.2$ km s$^{-1}$ constant with depth for HR 8844. The microturbulent velocities of the six stars are collected in Table 2.

### 4.3. Model Atmospheres and Spectrum Synthesis Calculations

Plane parallel model atmospheres assuming radiative equilibrium and hydrostatic equilibrium were computed using the ATLAS9 code (Kurucz 1992) for the appropriate fundamental parameters of each star. The linelist was built from Kurucz's gfall21oct16.dat<fnref n="7" /> which includes hyperfine splitting levels. The observed wavelengths and oscillator strengths were retrieved by querying the NIST<fnref n="8" /> Atomic Spectra Database (Kramida et al. 2017) for the following atoms or ions: He I, C II, O I, Mg II, Al I, Al II, Si II, S II, Ca II, Sc II, Ti II, Cr II, Mn II, Fe II, Sr II, Ba II, and Dy II. For the other species which lack data in the Atomic Spectra Database, we have used other references to retrieve their atomic data which are collected in Table 4. A grid of synthetic spectra was computed with SYNSPEC48

(Hubeny & Lanz 1992) to model the lines of 31 elements for HR 8844 and ν Cap. Computations were iterated varying the unknown abundance until minimization of the chi-square between the observed and synthetic spectrum was achieved. Abundances are derived for 34 elements for ν Cnc, 37 elements for Sirius A, and 37 elements for HD 72660, because these three stars have significantly lower projected rotational velocities.

### 4.4. The Derived Abundances of HR 8844

We used only unblended lines to derive the abundances. For a given element, the final abundance is a weighted mean of the abundances derived for each transition (the weights are derived from the NIST grade assigned to that particular transition). For several elements, in particular the heaviest elements, only one unblended line was available. These final abundances and their estimated uncertainties for HR 8844 are collected in Table 5. The determination of the uncertainties is discussed in the Appendix. Table 5 contains for each analyzed species the adopted laboratory wavelength, logarithm of oscillator strength, its source, the logarithm of the absolute abundance normalized to that of

hydrogen (on a scale where log(N<sub>H</sub>) = 12) for each transition, and the solar abundance adopted for that element. In this work, we adopted Grevesse & Sauval (1998) abundances for the Sun as

a reference. The final mean abundance and its estimated uncertainty are then given.

The light elements, He, C, O, and Mg, are found to be depleted in HR 8844. The helium abundance is found to be about 0.70 times the solar abundance of helium consistently from the He I lines near 4471 Å and near 5875.5 Å. The NLTE abundance correction for the λ 4471.48 Å He I line is very small as shown by Lemke (1989) for early-A-type stars and we have not corrected for it. Carbon is depleted, about 0.40 times the solar abundance from the analysis of the C II triplet at 4267 Å. Oxygen is depleted about 0.80 times the solar oxygen abundance from 12 O I transitions near 5330 Å and from 6155 to 6158 Å. Magnesium is also depleted by 0.45 times the solar abundance, aluminium is 0.8 times solar and silicon is about solar. Calcium and scandium are depleted by 0.70 times the solar abundances. As from titanium, all elements start to be mildly overabundant, except for iron. From the analysis of 12 lines, titanium is found to be about 1.41 times enriched respect to the solar abundance. The vanadium abundance is 1.88 times the solar abundance and the chromium abundance 1.45 times the solar abundance. The Mn II lines at 4206.37 Å and 4259.19 Å include hyperfine structure of the isotopes of manganese and yield two times the solar manganese abundance. The iron abundance which is solar has been derived mostly by using 16 Fe II lines of multiplets 37, 38, and 186 in the range 4500–4600 Å, whose atomic parameters are critically assessed in NIST (these are C+ and D quality lines).

lines are widely spaced and the continuum is fairly easy to trace in this spectral region. Their synthesis always yields consistent iron abundances from the various transitions with very little dispersion. The iron abundance is probably the most accurately determined of the abundances derived here. The Sr–Y–Zr triad is overabundant by modest amounts: about five times solar for strontium, about five times for yttrium, and 5.8 times solar for zirconium. Barium is enhanced by a factor of 9.3 and the Lanthanides by factors of 15 up to 100 times solar. Figure 7 illustrates the detection of a 10 times solar overabundance for barium from the Ba II line at 4554.03 Å.

Mercury is enhanced by 10,000 times the solar value. The overall abundance pattern of HR 8844 is therefore that light species tend to be almost all underabundant (He, C, O, Mg, Si, Ca, and Sc) while the iron-peak elements show mild enhancements (less than five times solar) and Sr, Y, Zr, Ba, the Lanthanides, and Hg show more and more pronounced overabundances (larger than five times solar), the largest overabundance being for Hg. The general trend therefore is that the heaviest elements are the most overabundant which strongly suggests that atomic diffusion be responsible for the chemical pattern of HR 8844.

The derived abundances of HR 8844 are compared with the previous determination in Royer et al. (2014) for the 12 elements in common in Table 6 and Figure 8. We find a reasonably good agreement (within ±0.25 dex) for C, O, Ca, Sc, Cr, Fe, and Sr.

### 4.5. The Derived Abundances for the Comparison Stars $\nu$ Cap, $\nu$ CnC, Sirius A, and HD 72660

Using the same method and linelist, we have derived the elemental abundances of the normal star $\nu$ Cap, the cool HgMn star $\nu$ Cnc, the hot Am stars Sirius A, and HD 72660 to compare the found abundances of HR 8844 to those of these four stars. The found abundances for these four comparison stars are collected in Table 7.

We compared the derived abundances for these four stars with published abundance studies in the literature as displayed in Table 8. We expect differences with previous analyses because of (i) differences in the adopted $v_e \sin i$ or $\xi$ and (ii) differences in the lines used and their atomic data. The found abundances for $\nu$ Cap are very close to solar for most elements in agreement with Adelman (1991) and Smith

& Dworetsky (1993). This star proves to be a very good normal comparison star. The abundances in Adelman (1991) differ slightly from ours for three reasons. Although he did use a similar effective temperature and surface gravity, Adelman adopted a null microturbulent velocity for $\nu$ Cap whereas we use 0.50 km s$^{-1}$. We did not necessarily use the same lines for a given element and the atomic data for the few lines have been upgraded to the latest values compiled in NIST.

For $\nu$ Cnc, our abundances are almost all larger than those reported in Adelman (1989), who used fundamental parameters and a microturbulent velocity similar to ours; however, he adopted a smaller $v_e \sin i = 13$ km s$^{-1}$, whereas we use 18 km s$^{-1}$. We therefore have to slightly enhance the abundances to reproduce the observed profiles. Note that we determine here for the first time the abundances of several Lanthanides in $\nu$ Cnc.

For Sirius A, we have compared our results with the most recent determinations of Landstreet (2011) for the elements up to Nickel and Cowley et al. (2016) for heavier elements. We use the same effective temperature, surface gravity, and a slightly lower microturbulent velocity (2.10 km s$^{-1}$ rather than 2.20 km s$^{-1}$ adopted by these authors). In his paper, Landstreet (2011) emphasizes that even for Sirius large differences in elemental abundances remain for C, Mg, Al, Si, S, Ca, V, Mn, Ni, and even Fe from one author to another. We find good

agreement (i.e., within ±0.20 dex) with Landstreet's (2011) abundances for O, Ca, Cr, Mn, Fe, Ni, Sr, and Ba. For elements heavier than barium, we find a fair agreement with Cowley et al. (2016) abundances for La, Pr, Nd, Sm, and Hf within ±0.20 dex of their determinations.

For HD 72660, we have compared our abundances with those of Golriz & Landstreet (2016) as we have used similar effective temperature, surface gravity, projected equatorial velocity, and microturbulent velocity. We find a fair agreement with Golriz & Landstreet (2016) for the abundances of several elements: C, Mg, Al, Si, S, Sc, Ti, V, Cr, Ni, and Zr.

In Figure 9, we compare the found abundances for HR 8844 with our new determinations for the four comparison stars. As ν Cnc, and Sirius A, HR 8844 displays the characteristic underabundances for most elements lighter than titanium and pronounced overabundances for elements heavier which CP stars harbour. The overabundances of HR 8844 are modest for the iron-peak elements, but increase for the Sr-Y-Zr triad and barium (of the order of 10 times solar) and for the Lanthanides and of the order of $10^4$ solar for mercury. The overabundance of manganese and mercury; the underabundances of calcium and scandium and of the lightest elements; the mild overabundances of the iron-peak elements, of the Sr-Y-Zr triad; of barium and several Rare Earths, show that HR 8844 is a new hot Am star which also

displays characteristic enhancements of the coolest HgMn stars (as HD 72660 and Sirius A do). We therefore propose that HR 8844 be a new transition object between the Am stars and the coolest HgMn stars and as such is a very interesting star.

## 5. Conclusion

We report here on detailed abundance determinations of the A0V star HR 8844, hitherto considered as a “normal star.” Our analysis definitely establishes that HR 8844 is a new CP star, probably a hot Am star (as Sirius A and HD 72660 are), extending the realm of Am stars to significantly higher temperatures. As HD 72660 and Sirius A, HR 8844 may well be a transition object between the Am stars and the coolest HgMn star and as such is a very interesting object. We are undertaking a monitoring of HR 8844 over its rotation period (which must be smaller than 5 days assuming a radius of about 2 solar radii for an A0V star) to search for variability due to the presence of spots or a companion.

We thank the OHP night assistants for their helpful support during the three observing runs. This work has made use of the VALD database (Ryabchikova et al. 2011), operated at Uppsala University, the Institute of Astronomy RAS in Moscow, and the University of Vienna We have also used the NIST Atomic Spectra Database (version 5.4) available http://physics.nist.gov/asd. We also acknowledge the use of the ELODIE archive at OHP available at http://atlas.obs-hp.fr/elodie/.

## Appendix
### Determination of Uncertainties

For a representative line of a given element, six major sources are included in the uncertainty determinations: the uncertainty on the effective temperature ($\sigma_{T_{eff}}$), on the surface gravity ($\sigma_{log g}$), on the microturbulent velocity ($\sigma_{\xi_i}$), on the apparent rotational velocity ($\sigma_{\nu_e \sin i}$), the oscillator strength ($\sigma_{log gf}$), and the continuum placement ($\sigma_{cont}$). These uncertainties are supposed to be independent, so that the total uncertainty $\sigma_{tot_i}$ for a given transition (i) is

$$ \sigma_{tot_i}^2 = \sigma_{T_{eff}}^2 + \sigma_{log g}^2 + \sigma_{\xi_i}^2 + \sigma_{\nu_e \sin i}^2 + \sigma_{log gf}^2 + \sigma_{cont}^2 \quad (1) $$

The mean abundance, $\langle [\frac{X}{H}] \rangle$, is then computed as a weighted mean of the individual abundances $[X/H]_i$ derived for each transition (i):

$$ \langle \left[ \frac{X}{H} \right] \rangle = \frac{\sum_i \left( \left[ \frac{X}{H} \right]_i / \sigma_{\text{tot},i}^2 \right)}{\sum_i (1/\sigma_{\text{tot},i}^2)} \quad (2) $$

and the total error, $\sigma$ is given by

$$ \frac{1}{\sigma^2} = \sum_{i=1}^{N} (1/\sigma_{\text{tot},i}^2), \quad (3) $$

where N is the number of lines per element. The uncertainties $\sigma$ for each element are collected in Table 9.
