The First Dedicated Survey of Atmospheric Escape from Planets Orbiting F Stars
Morgan Saidel, Shreyas Vissapragada, Heather Knutson +9
Hydrodynamic escape can strip the envelopes of close-in exoplanets, but most observations of atmospheric mass loss to date have been confined to planets orbiting K and M dwarfs. A…
From Earths to Super-Earths: Five New Small Planets Transiting M Dwarf Stars
Jonathan Gomez Barrientos, Heather A. Knutson, Morgan Saidel +39
Earth-sized planets transiting M dwarf stars present one of the best opportunities with current facilities for studying the atmospheric and bulk compositions of terrestrial worlds.…
Validation of a Third Earth-sized Planet in the TOI-2267 Binary System
Michael Greklek-McKeon, Jonathan Gomez Barrientos, Heather A. Knutson +13
We report the validation of a third terrestrial exoplanet in the nearby (22 pc) TOI-2267 system. TOI-2267 is a binary system with stellar components TOI-2267A (M5, 3030 K) and TOI-…
Kepler-1624b Has No Significant Transit Timing Variations
Haedam Im, Morgan Saidel, Heather A. Knutson +9
It is relatively rare for gas giant planets to have resonant or near-resonant companions, but these systems are particularly useful for constraining planet formation and migration…
Stringent Upper Bounds on Atmospheric Mass Loss from Three Neptune-Sized Planets in the TOI-4010 System
Morgan Saidel, Shreyas Vissapragada, Michael Zhang +6
Photoevaporative models predict that the lower edge of the Neptune desert is sculpted by atmospheric mass loss. However, the stellar high energy fluxes that power hydrodynamic esca…
Validation of TESS Planet Candidates with Multi-Color Transit Photometry and TRICERATOPS+
Jonathan Gomez Barrientos, Michael Greklek-McKeon, Heather A. Knutson +33
We present an upgraded version of TRICERATOPS, a software package designed to calculate false positive probabilities for planet candidates identified by the Transiting Exoplanet Su…
