Abstract:
We present precise measurements of radial (RV) and projected
rotational (vsini) velocities of a sample of 258 M6 to L2 dwarfs with
multiepoch, high-resolution (λ/Δλ=22500),
near-infrared (1.514-1.696µm) spectroscopic observations reported
in the Apache Point Observatory Galactic Evolution Experiment Data
Release 17. The spectra were modeled using a Markov Chain Monte Carlo
forward-modeling method, which achieved median precisions of
σRV=0.4km/s and σvsini=1.1km/s. One-half of our sample
(138 sources) are previously known members of nearby young clusters
and moving groups, and we identified three new kinematic members of
the Argus or Carina Near moving groups, 2MASS J05402570+2448090,
2MASSJ14093200+4138080, and 2MASS J21272531+5553150. Excluding these
sources, we find that the majority of our sample have kinematics
consistent with the Galactic thin disk, and 11 sources are associated
with the intermediate thin/thick disk. The field sample has a velocity
dispersion of 38.2±0.3km/s, equivalent to an age of 3.30±0.19Gyr
based on empirical age-velocity dispersion relations, and a median
vsini of 17km/s. For 172 sources with multiepoch observations, we
identified 37 as having significant RV variations, and determined
preliminary orbit parameters for 26 sources with four or more epochs,
nine of which are short-period binary candidates. For 40 sources with
photometric variability periods from the literature less than 5 days
and vsini>20km/s, we find a decline in projected radii (Rsini) with
age congruent with evolutionary models. Finally, we also present
multiepoch RV and vsini measurements for additional 444 candidate
ultracool dwarfs.
Description:
Our ultracool dwarf (UCD) sample was curated from APOGEE DR17
(Abdurro'uf+ 2022, III/286) of SDSS-IV based on observations obtained
with the 2.5m Sloan Foundation Telescope at the Apache Point
Observatory and the 2.5m du Pont Telescope at the Las Campanas
Observatory.
Our "gold" sample was based on sources with classifications of M6 and
later as reported in SIMBAD, the Late-Type Extension to MoVeRS
(Theissen+ 2016, J/AJ/151/41 & 2017, J/AJ/153/92),
Reyle (2018, J/A+A/619/L8), Best+ (2021, J/AJ/161/42), or reported in
this work. We use the most recent spectroscopic classification as our
adopted value. See Section 2.1.
The majority of sources in our full sample lack published
spectroscopic classifications. To bolster this sample, we obtained
additional low-resolution optical spectra with the Kast Double
Spectrograph on the Shane 3m Telescope at the Lick Observatory over
multiple nights between 2018 January 21 and 2022 March 11. We used the
600/7500 grating and 2" slit to obtain 6000-9000Å spectra at an
average resolution of R∼1800. See Section 2.2.

Note (1): Flag as follows:
b = Known or candidate binary.
d = Reported in the literature or a new member of young moving groups.
e = Reported as a member of NGC 1333 in Cantat-Gaudin+ 2018, J/A+A/618/A93;
Yao+ 2018, J/ApJ/869/72; Cantat-Gaudin & Anders 2020, J/A+A/633/A99;
Cantat-Gaudin+ 2020, J/A+A/640/A1, but we did not identify because
NGC 1333 is not included in BANYAN Σ.
f = Reported as a member of the Castor Moving Group in
Zuckerman+ 2013ApJ...778....5Z 2013ApJ...778....5Z, but we did not identify it because the
Castor Moving Group is not included in BANYAN Σ.
Note (2): Galactic thin disk (D), thick disk (TD),
intermediate populations (D/TD) are assigned according to probability
ratios P(TD)/P(D)<0.1, P(TD)/P(D)>10, and 0.1<P(TD)/P(D)<10,
respectively, following Bensby+ 2003, J/A+A/410/527
Note (3): BANYAN Σ young moving group name abbreviation follows those
defined in Gagne+ 2018, J/ApJ/856/23: AB Doradus (ABDMG), Argus (ARG),
Carina- Near (CARN), Coma Berenices (CBER), Corona Australis (CRA),
Hyades (HYA), Taurus (TAU), Upper Centaurus-Lupus (UCL), Upper Corona
Australis (UCRA), and Upper Scorpius (USCO).

Note (1): The large uncertainties of Galactic orbital parameters of
2MASS J05350162-0521489 are due to its large proper motion uncertainty
(µRAcos(DE)=0±44mas/yr and µDE=0±40mas/yr;
Cutri+ 2014, II/328).
