A Catalog of Cool Dwarf Targets for the Transiting Exoplanet Survey Satellite

<jats:title>Abstract</jats:title> <jats:p>We present a catalog of cool dwarf targets (<jats:inline-formula> <jats:tex-math> </jats:tex-math> <jats:inline-graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="ajaab710ieqn1.gif" xlink:type="simple"/> </jats:inline-formula>, <jats:italic>T</jats:italic> <jats:sub>eff</jats:sub> ≲ 4000 K) and their stellar properties for the upcoming <jats:italic>Transiting Exoplanet Survey Satellite</jats:italic> (<jats:italic>TESS</jats:italic>), for the purpose of determining which cool dwarfs should be observed using two minute observations. <jats:italic>TESS</jats:italic> has the opportunity to search tens of thousands of nearby, cool, late K- and M-type dwarfs for transiting exoplanets, an order of magnitude more than current or previous transiting exoplanet surveys, such as <jats:italic>Kepler</jats:italic>, <jats:italic>K2</jats:italic>, and ground-based programs. This necessitates a new approach to choosing cool dwarf targets. Cool dwarfs are chosen by collating parallax and proper motion catalogs from the literature and subjecting them to a variety of selection criteria. We calculate stellar parameters and <jats:italic>TESS</jats:italic> magnitudes using the best possible relations from the literature while maintaining uniformity of methods for the sake of reproducibility. We estimate the expected planet yield from <jats:italic>TESS</jats:italic> observations using statistical results from the <jats:italic>Kepler</jats:italic> mission, and use these results to choose the best targets for two minute observations, optimizing for small planets for which masses can conceivably be measured using follow-up Doppler spectroscopy by current and future Doppler spectrometers. The catalog is available in machine readable format and is incorporated into the <jats:italic>TESS</jats:italic> Input Catalog and <jats:italic>TESS</jats:italic> Candidate Target List until a more complete and accurate cool dwarf catalog identified by ESA’s <jats:italic>Gaia</jats:italic> mission can be incorporated.</jats:p>
