Abstract:
Orbital characteristics based on Gaia Early Data Release 3 astrometric
parameters are analyzed for ∼1700 r-process-enhanced (RPE;
[Eu/Fe]>+0.3) metal-poor stars ([Fe/H]≤-0.8) compiled from the
R-Process Alliance, the GALactic Archaeology with HERMES (GALAH) DR3
survey, and additional literature sources. We find dynamical clusters
of these stars based on their orbital energies and cylindrical actions
using the HDBSCAN unsupervised learning algorithm. We identify
36 chemodynamically tagged groups (CDTGs) containing between five and
22 members; 17 CDTGs have at least 10 member stars. Previously known
Milky Way (MW) substructures such as Gaia-Sausage-Enceladus, the
splashed disk, the metal-weak thick disk, the Helmi stream, LMS-1
(Wukong), and Thamnos are reidentified. Associations with MW globular
clusters are determined for seven CDTGs; no recognized MW dwarf galaxy
satellites were associated with any of our CDTGs. Previously
identified dynamical groups are also associated with our CDTGs, adding
structural determination information and possible new identifications.
Carbon-enhanced metal-poor RPE (CEMP-r) stars are identified among the
targets; we assign these to morphological groups in a Yoon-Beers
A(C)c versus [Fe/H] diagram. Our results confirm previous dynamical
analyses that showed RPE stars in CDTGs share common chemical
histories, influenced by their birth environments.
Description:
This work aims to expand on the efforts of Roederer+ (2018, J/AJ/156/179)
and Gudin+ (2021, J/ApJ/908/79), analyzing the chemodynamically tagged
groups (CDTGs) present among stars in an updated r-process-enhanced
(RPE) stellar sample, which includes stars from the literature and the
published GALactic Archaeology with HERMES Data Release 3 (GALAH DR3;
Buder+ 2021, J/MNRAS/506/150) catalog of metal-poor ([Fe/H]≤-0.8)
stars. The procedures employed closely follow the work of
Shank+ (2022, J/ApJ/926/26).

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).
Note (G2): V magnitude of the star as determined by the transformations from
Gmag to Vmag 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 corrected inverse parallax distance (1/(pls+0.026)) is based
on Huang+ (2021ApJ...907...68H 2021ApJ...907...68H). The corrected inverse
parallax distance error follows (e_plx/((plx+0.026)2))
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] = logε(Fe)-logε(Fe)☉, where Solar value
of 7.50 taken from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A
[C/Fe] = logε(C)-logε(C)☉-[Fe/H], where Solar value
of 8.43 taken from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A
[Mg/Fe] = logε(Mg)-logε(Mg)☉-[Fe/H], where Solar value
of 7.60 taken from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A
[Sr/Fe] = logε(Sr)-logε(Sr)☉-[Fe/H], where Solar value
of 2.87 taken from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A
[Y/Fe] = logε(Y)-logε(Y)☉-[Fe/H], where Solar value
of 2.21 taken from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A
[Ba/Fe] = logε(Ba)-logε(Ba)☉-[Fe/H], where Solar value
of 2.18 taken from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A
[Eu/Fe] = logε(Eu)-logε(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]+logε(C)☉);
solar value of 8.43 taken 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): CEMP Flag as follows:
C = Carbon-Enhanced Metal-Poor (CEMP) if [C/Fe]c > +0.7;
I = CEMP-intermediate if +0.5 < [C/Fe]c ≤ +0.7;
N = Carbon-Normal if [C/Fe]c ≤ +0.5
X = no [C/Fe]c information.
Note (G9): The Action-based GAlaxy Modeling Architecture (AGAMA) package is
described in Vasiliev 2019MNRAS.482.1525V 2019MNRAS.482.1525V
Note (G10): Reference for Vmag as follows:
APASS DR9 = AAVSO Photometric All Sky Survey,

GSC2.3 = Lasker+ 2008AJ....136..735L 2008AJ....136..735L; Cat. I/305

NLTT = Salim & Gould 2003, J/ApJ/582/1011
Note (G11): Reference for distance used in AGAMA fitting.
STARHORSE (Anders+ 2022, I/354) prioritized over BAILER-JONES
(Bailer-Jones+ 2021, I/352) unless STARHORSE distance has relative
error greater than 0.3, if both have a relative error greater than 0.3
we adopt no distance estimate. Sources with "GAIA EDR3" use the
inverse Gaia EDR3 parallax for the distance.
Note (G12): 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.
Note (G13): Classification as in Table 1, as follows:
r-I = Main r-process: +0.3<[Eu/Fe]≤+0.7, [Ba/Eu]<0.0
r-II = Main r-process: +0.7<[Eu/Fe]≤+2.0, [Ba/Eu]<0.0
r-III = Main r-process: [Eu/Fe]>+2.0, [Ba/Eu]←0.5
CEMP = Carbon enhanced: [C/Fe]>+0.7
CEMP-r = CEMP and RPE: [C/Fe]>+0.7, [Eu/Fe]>+0.3, [Ba/Eu]<0.0
