Stellar surface inhomogeneities as a potential source of the atmospheric signal detected in the K2-18 b transmission spectrum
Thomas Barclay, Veselin B. Kostov, Knicole D. Colón +5
Transmission spectroscopy of transiting exoplanets is a proven technique that can yield information on the composition and structure of a planet's atmosphere. However, transmission…
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…
The Pandora SmallSat: Multiwavelength Characterization of Exoplanets and their Host Stars
Elisa V. Quintana, Knicole D. Colón, Gregory Mosby +24
Pandora is a SmallSat mission designed to study the atmospheres of exoplanets, and was selected as part of NASA's Astrophysics Pioneers Program. Transmission spectroscopy of transi…
TOI-220 : a warm sub-Neptune discovered by TESS
S. Hoyer, D. Gandolfi, D. J. Armstrong +77
In this paper we report the discovery of TOI-220 , a new sub-Neptune detected by the Transiting Exoplanet Survey Satellite (TESS) and confirmed by radial velocity follow-up obse…
The TESS Objects of Interest Catalog from the TESS Prime Mission
Natalia M. Guerrero, S. Seager, Chelsea X. Huang +102
We present 2,241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its two-year prime mission. We list these candidates in the…
TOI-1259Ab -- a gas giant planet with 2.7% deep transits and a bound white dwarf companion
David V. Martin, Kareem El-Badry, Vedad Kunovac Hodžić +33
We present TOI-1259Ab, a 1.0 Rjup gas giant planet transiting a 0.71 Rsun K-dwarf on a 3.48 day orbit. The system also contains a bound white dwarf companion TOI-1259B with a proje…
