Abstract:
Multi-epoch radial velocity measurements of stars can be used to identify
stellar, substellar, and planetary-mass companions. Even a small number
of observation epochs can be informative about companions, though there
can be multiple qualitatively different orbital solutions that fit the
data. We have custom-built a Monte Carlo sampler (The Joker) that delivers
reliable (and often highly multimodal) posterior samplings for companion
orbital parameters given sparse radial velocity data. Here we use The
Joker to perform a search for companions to 96231 red giant stars observed
in the APOGEE survey (DR14) with ≥3 spectroscopic epochs. We select stars
with probable companions by making a cut on our posterior belief about
the amplitude of the variation in stellar radial velocity induced by
the orbit. We provide (1) a catalog of 320 companions for which the stellar
companion's properties can be confidently determined, (2) a catalog of
4898 stars that likely have companions, but would require more observations
to uniquely determine the orbital properties, and (3) posterior samplings
for the full orbital parameters for all stars in the parent sample. We
show the characteristics of systems with confidently determined companion
properties and highlight interesting systems with candidate compact
object companions.
Description:
All data used in this work come from the publicly available data
release 14 (DR14) of the APOGEE survey (Abolfathi et al.
2018ApJS..235...42A 2018ApJS..235...42A; Majewski et al. 2017AJ....154...94M 2017AJ....154...94M), a component
of the Sloan Digital Sky Survey IV (SDSS-IV; Gunn et al.
2006AJ....131.2332G 2006AJ....131.2332G; Blanton et al. 2017AJ....154...28B 2017AJ....154...28B). APOGEE is
designed to map stars across much of the Milky Way by obtaining
high-resolution (R∼22500) infrared (H-band) spectroscopy of primarily
RGB stars. Targets are selected with simple color and brightness cuts,
but the survey uses fiber-plugged plates with a maximum of 300 fibers
per∼1.5 deg2 field of view, leading to "pencil-beam"-like sampling
of the Galactic stellar distribution. In order to meet requirements on
signal-to-noise ratio, most APOGEE stars are observed multiple times
in a series of "visits", typically with at least one visit separated
from others by a month or more in order to help identify binary stars.
We use the primary data products from APOGEE DR14 (i.e., the allStar
and allVisit files), which contain 258475 unique source IDs (APOGEE_ID)
and 1054381 unique visits. We select all stars with ≥3 visits that
each pass a set of quality cuts. After these cuts, and the requirement
of ≥3 visits for a given star, we are left with 397559 visits for
96231 unique sources.

Global notes:
Note (G1): Unique apStar identifier: apogee.[ns].[sc].APSTAR_VERS.LOC.STAR,
where [ns] is for APOGEE North/South, [sc] is for survey/commissioning.
Note (G2): Unique ASPCAP identifier: apogee.[ns].[sc].RESULTS_VERS.LOC.STAR.
Note (G3): See http://www.sdss.org/dr13/algorithms/bitmasks/ for APOGEE bitmask
definitions.
Note (G4): Perhaps not currenlty useful because of issues with understanding RV
errors.
Note (G5): See http://www.sdss.org/dr14/algorithms/bitmasks/ for APOGEE bitmask
definitions.
Note (G6): In order given in PARAM_SYMBOL array in HDU3: Teff, logg, vmicro,
[M/H], [C/M], [N/M], [alpha/M], vsini/vmacro.
Note (G7): All expressed in logarithmic abundance relative to H ([X/H]),
in order given in ELEM_SYMBOL array in HDU3.
Note (G8): All expressed in logarithmic abundance relative to M ([X/M]),
in order given in ELEM_SYMBOL array in HDU3.
Note (G9): Clean flag as follows:
0 = When the orbits look reasonable;
1 = When the orbits look reasonable but the value of the inferred excess
variance is large;
2 = When the orbits are clearly poor fits.
Many of the stars flagged as "2" look like they may be triple systems, because
they tend to have variations in radial velocity over two distinct timescales
that are never well-fit by a single Keplerian orbit. The stars flagged as "1"
tend to be either upper RGB stars, where astrophysical surface jitter can lead
to RV modulations, or SB2 systems, where absorption lines from the secondary
confuse the RV pipeline and lead to strange RV signals.
