Final Report for SAG 22: A Target Star Archive for Exoplanet Science

Natalie R. Hinkel, Joshua Pepper, Christopher C. Stark +33

Present and upcoming NASA missions will be intensively observing a selected, partially overlapping set of stars for exoplanet studies. Key physical and chemical information about t…

The young HD 73583 (TOI-560) planetary system: Two 10-M mini-Neptunes transiting a 500-Myr-old, bright, and active K dwarf

O. Barragán, D. J. Armstrong, D. Gandolfi +103

We present the discovery and characterisation of two transiting planets observed by \textit{TESS} in the light curves of the young and bright (V=9.67) star HD73583 (TOI-560). We pe…

The TESS Mission Target Selection Procedure

Michael Fausnaugh, Ed Morgan, Roland Vanderspek +61

We describe the target selection procedure by which stars are selected for 2-minute and 20-second observations by TESS. We first list the technical requirements of the TESS instrum…

Extreme Precision Radial Velocity Working Group Final Report

Jonathan Crass, B. Scott Gaudi, Stephanie Leifer +33

Precise mass measurements of exoplanets discovered by the direct imaging or transit technique are required to determine planet bulk properties and potential habitability. Furthermo…

Optimized modeling of Gaia-Hipparcos astrometry for the detection of the smallest cold Jupiter and confirmation of seven low mass companions

Fabo Feng, R. Paul Butler, Hugh R. A. Jones +6

To fully constrain the orbits of low mass circumstellar companions, we conduct combined analyses of the radial velocity data as well as the Gaia and Hipparcos astrometric data for…

Wolf 503 b: Characterization of a Sub-Neptune Orbiting a Metal-Poor K Dwarf

Alex S. Polanski, Ian J. M. Crossfield, Jennifer A. Burt +35

Using radial velocity measurements from four instruments, we report the mass and density of a sub-Neptune orbiting the quiet K-dwarf Wolf 503 (HIP…
