Know thy star, know thy planet: Chemo-kinematically characterizing TESS
  targets
  The Transiting Exoplanet Survey Satellite (TESS) has already begun to
discover what will ultimately be thousands of exoplanets around nearby cool
bright stars. These potential host stars must be well-understood to accurately
characterize exoplanets at the individual and population levels. We present a
catalogue of the chemo-kinematic properties of 2,218,434 stars in the TESS
Candidate Target List using survey data from Gaia DR2, APOGEE, GALAH, RAVE,
LAMOST, and photometrically-derived stellar properties from SkyMapper. We
compute kinematic thin disc, thick disc, and halo membership probabilities for
these stars and find that though the majority of TESS targets are in the thin
disc, 4% of them reside in the thick disc and <1% of them are in the halo. The
TESS Objects of Interest in our sample also display similar contributions from
the thin disc, thick disc, and halo with a majority of them being in the thin
disc. We also explore metallicity and [alpha/Fe] distributions for each
Galactic component and show that each cross-matched survey exhibits metallicity
and [alpha/Fe] distribution functions that peak from higher to lower
metallicity and lower to higher [alpha/Fe] from the thin disc to the halo. This
catalogue will be useful to explore planet occurrence rates, among other
things, with respect to kinematics, component-membership, metallicity, or
[alpha/Fe].
