Abstract:
Orbital characteristics based on Gaia Early Data Release 3 astrometric
parameters are analyzed for ∼8000 metal-poor stars ([Fe/H]≤-0.8)
compiled from the Radial Velocity Experiment (RAVE) Data Release 6.
Selected as metal-poor candidates based on broadband photometry, RAVE
collected moderate-resolution (R∼7500) spectra in the region of the Ca
triplet for these stars. About 20% of the stars in this sample also
have medium-resolution (1200≲R≲2000) validation spectra obtained
over a 4yr campaign from 2014 to 2017 with a variety of telescopes. We
match the candidate stars to photometric metallicity determinations
from the Huang+ 2022ApJ...925..164H 2022ApJ...925..164H recalibration of the SkyMapper
Southern Survey Data Release 2. We obtain dynamical clusters of these
stars from the orbital energy and cylindrical actions using the
HDBSCAN unsupervised learning algorithm. We identify 179 dynamically
tagged groups (DTGs) with between 5 and 35 members; 67 DTGs have at
least 10 member stars. Milky Way (MW) substructures such as
Gaia-Sausage-Enceladus, the Metal-weak Thick Disk, the Splashed Disk,
Thamnos, the Helmi Stream, and LMS-1 (Wukong) are identified.
Associations with MW globular clusters are determined for 10 DTGs; no
recognized MW dwarf galaxies were associated with any of our DTGs.
Previously identified dynamical groups are also associated with our
DTGs, with emphasis placed on their structural determination and
possible new identifications. We identify chemically peculiar stars as
members of several DTGs; we find 22 DTGs that are associated with
r-process-enhanced stars. Carbon-enhanced metal-poor (CEMP) stars are
identified among the targets with available spectroscopy, and we
assign these to morphological groups following the approach given by
Yoon+ 2016, J/ApJ/833/20.
Description:
The RAVE DR6 survey (Steinmetz+ 2020, III/283) forms the basis for the
compilation of our data set. We construct three samples, the Full
Sample (section 2.1), the Initial Sample (section 2.2 and Table 8),
and the Final Sample (section 2.3 and Table 9).

Note (1): Object group as follows:
III = Group III star ([Fe/H]<-3.5, centered on A(C)∼6.8);
II = Group II star (metallicity range of -5.0≲[Fe/H]≲-2.5, and, in
contrast to the Group III stars, exhibit a clear dependence of
A(C) on [Fe/H]);
I = Group I star (CEMP-no stars that fall into neither of these groups,
but are scattered throughout the region primarily occupied by the
CEMP-s/rs stars);

Global notes:
Note (G1): We adopt the nomenclature for previously identified DTGs and CDTGs
from Yuan+ 2020ApJ...898L..37Y 2020ApJ...898L..37Y
Note (G2): Telescope used for spectrum as follows:
GEMS = the Gemini-South 8.1m telescope
KPNK = the Kitt Peak National Observatory (KPNO) Mayall 4m telescope with
KOSMOS.
KPNR = the Kitt Peak National Observatory (KPNO) Mayall 4m telescope
NTTE = the ESO New Technology (NTT) 3.58m telescope
SOAR = the Southern Astrophysical Research (SOAR) 4.1m telescope
Note (G3): 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 (G4): 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 (G5): 50 percentile error as estimated from the 84 percentile distance
and the 16 percentile distance, (dist84-dist16)/2
Note (G6): The absolute carbon corrected for evolutionary effects from
Placco+ (2014, J/ApJ/797/21) ([C/Fe]c+[Fe/H]+log(ε)Carbon,Solar)
(Taken from solar value of 8.43 from Asplund+ 2009ARA&A..47..481A 2009ARA&A..47..481A).
Note (G7): The [C/Fe] flag as follows:
D = the carbon abundance ([C/Fe]) is detected from n-SSPP;
U = an upper limit by n-SSPP;
L = a lower limit by n-SSPP;
N = none is detected by n-SSPP.
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): Alpha abundance flag as follows:
D = the alpha abundance ([α/Fe]) is detected from n-SSPP;
U = an upper limit by n-SSPP;
L = a lower limit by n-SSPP;
N = none is detected by n-SSPP.
Note (G10): The Reference for the star as given by "RAVE DR6" for the sample
of stars from Steinmetz+ 2020, III/283 sample and
"RAVE DR5" for the sample of stars from Kunder+ (2017, III/279)
and "RAVE DR4" for the star from Kordopatis+ (2013, III/272).
Note (G11): Procedure used to determine adopted stellar parameters --
Average = difference between [Fe/H]S and [Fe/H]P is less ≤0.5dex
Spectroscopic = only [Fe/H]S is available
Photometric = only [Fe/H]P is available,
Note (G12): Reference for Vmag as follows:
APASS = AAVSO Photometric All Sky Survey DR9 (see II/336);
APOP = Absolute Proper motions Outside the Plane (Qi+, 2015, I/331)
NOMAD-1 = see I/297
SPM4 = Yale/San Juan Southern Proper Motion Catalog 4
(Girard+, 2011, I/320)
UCAC4 = see I/322
Note (G13): Reference for the distance used in AGAMA. Dist-s (STARHORSE) is
prioritized over Dist-b (BAILER-JONES) unless RelErr-s>0.3. If both
RelErr-s and RelErr-b are >0.3 we adopt no distance estimate.
