Abstract:
We construct a sample of 644 carbon-enhanced metal-poor (CEMP) stars
with abundance analyses based on moderate- to high-resolution
spectroscopic studies. Dynamical parameters for these stars are
estimated based on radial velocities, Bayesian parallax-based distance
estimates, and proper motions from Gaia EDR3 and DR3, supplemented by
additional available information where needed. After separating our
sample into the different CEMP morphological groups in the Yoon-Beers
diagram of absolute carbon abundance versus metallicity, we used the
derived specific energies and actions (E, Jr, Jph, Jz) to cluster them
into Chemodynamically Tagged Groups (CDTGs). We then analyzed the
elemental-abundance dispersions within these clusters by comparing
them to the dispersion of clusters that were generated at random. We
find that, for the Group I (primarily CEMP-s and CEMP-r/s) clustered
stars, there exist statistically insignificant intracluster
dispersions in [Fe/H], [C/Fe]c (evolution corrected carbon), and
[Mg/Fe] when compared to the intracluster dispersions of randomly
clustered Group I CEMP stars. In contrast, the Group II (primarily
CEMP-no) stars exhibit clear similarities in their intracluster
abundances, with very low, statistically significant, dispersions in
[C/Fe]c and marginally significant results in [Mg/Fe]. These results
strongly indicate that Group I CEMP stars received their carbon
enhancements from local phenomena, such as mass transfer from an
evolved binary companion in regions with extended star formation
histories, while the CDTGs of Group II CEMP stars formed in
low-metallicity environments that had already been enriched in carbon,
likely from massive rapidly rotating ultra- and hyper-metal-poor stars
and/or supernovae associated with high-mass early- generation stars.
Description:
A compilation of carbon-enhanced metal-poor (CEMP) stars with
abundance analyses based on high-resolution spectroscopy was published
by Yoon+ 2016, J/ApJ/833/20 and it serves as the basis for this work.
We also include CEMP surveys with similar analyses --
Sakari+ 2018, J/ApJ/868/110; Hansen+ 2018, J/ApJ/858/92;
Ezzeddine+ 2020, J/ApJ/898/150; Holmbeck+ 2020, J/ApJS/249/30;
Rasmussen+ 2020, J/ApJ/905/20; Zepeda+ 2022, J/ApJ/927/13;
Pristine (Lucchesi+ 2022, J/MNRAS/511/1004), and GALAH
(Buder+ 2021, J/MNRAS/506/150).
Note that we have chosen to exclusively adopt reported abundances
based on the local thermodynamical equilibrium (LTE) assumption.

Note on table4.dat, table13.dat and table16.dat: To perform our clustering
exercise, we employ HDBSCAN
(https://hdbscan.readthedocs.io/en/latest/how_hdbscan_works.html).
This method groups data by density in the phase space considered
(orbital energies and cylindrical actions), then places the clusters
into a hierarchy based on how they change when the requisite density
belonging to a cluster changes. We refer the interested reader to
Campello+ (Campello R. J. G. B., Moulavi D. and Sander J. 2013
Advances in Knowledge Discovery and Data Mining ed J. Pei et al.
(Berlin: Springer) 160) and Shank+ (2022ApJ...926...26S 2022ApJ...926...26S) for a full
description of HDBSCAN.
Note on table5.dat, table14.dat and table17.dat: We employ the Action-based
GAlaxy Modeling Architecture (AGAMA;
https://github.com/GalacticDynamics-Oxford/Agama) package
(Vasiliev 2019MNRAS.482.1525V 2019MNRAS.482.1525V), which uses the radial velocities,
distances, and proper motions of stars to derive orbital parameters
for stars in the initial sample.

Note (1): Measurements include the biweight location and scale of the
abundances for each CDTG (CDTG); the mean and the standard error of the
mean (using biweight estimates) for both the location and scale of the
abundances of the CDTGs, along with the IQR of the abundances of the
CDTGs and then the the biweight location and scale of the Final Sample
for each of the abundances, along with the IQR for each of the
abundances in the Final Sample.

Global notes:
Note (G1): The source catalog types for these star names include primarily
GALAH DR3 identifiers (Section 2.1.2) or the identifiers used in the
literature (Section 2.1.1).
HE 0132-2429 in tables 2, 11 and 12 were very likely a misprint for
HE 0132-2439; corrected at CDS.
Note (G2): V magnitude of the star as determined by the transformations from
G mag to V mag using the equation from Riello+ 2021, J/A+A/649/A3:
V=G+0.02704-0.01424*(BP-RP)+0.2156*(BP-RP)2-0.01426(BP-RP)3
Note (G3): The inverse parallax distance follows e_plx/(plx2)
Note (G4): 50 percentile error as estimated from the 84 percentile distance
and the 16 percentile distance, (dist84-dist16)/2
Note (G5): logarithmic abundance ratios given by:
[Fe/H] = loge(Fe)-loge(Fe)☉, where Solar value of 7.50 taken
from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A;
[C/Fe] = loge(C)-loge(C)☉-[Fe/H], where Solar value of 8.43 taken
from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A;
[Mg/Fe] = loge(Mg)-loge(Mg)☉-[Fe/H], where Solar value of 7.60 taken
from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A;
[Sr/Fe] = loge(Sr)-loge(Sr)☉-[Fe/H], where Solar value of 2.87 taken
from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A;
[Y/Fe] = loge(Y)-loge(Y)☉-[Fe/H], where Solar value of 2.21 taken
from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A;
[Ba/Fe] = loge(Ba)-loge(Ba)☉-[Fe/H], where Solar value of 2.18 taken
from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A;
[Eu/Fe] = loge(Eu)-loge(Eu)☉-[Fe/H], where Solar value of 0.52 taken
from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A
Note (G6): The absolute carbon corrected for evolutionary effects from
Placco+ 2014, J/ApJ/797/21, ([C/Fe]c+[Fe/H]+loge(C)☉)
(Taken from solar value of 8.43 from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A).
Note (G7): The abundance flag for [X/Fe] as follows:
D = the abundance ([X/Fe]) is detected by Ref;
U = an upper limit Ref;
L = a lower limit by Ref;
X = none is detected by Ref.
Note (G8): The Action-based GAlaxy Modeling Architecture (AGAMA) package is
described in Vasiliev 2019MNRAS.482.1525V 2019MNRAS.482.1525V
Note (G9): The source catalog types for these star names include primarily
GALAH DR3 identifiers (Section 2.1.2) or the identifiers used in the
literature (Section 2.1.1).
