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…

Methane on the temperate exo-Saturn TOI-199b

Aaron Bello-Arufe, Renyu Hu, Mantas Zilinskas +10

Temperate ( K) gas giants represent an unexplored frontier in exoplanet atmospheric spectroscopy. Orbiting a G-type star every days, the Saturn-mass exopl…

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…

Two warm Earth-sized exoplanets and an Earth-sized candidate in the M5V-M6V binary system TOI-2267

S. Zúñiga-Fernández, F. J. Pozuelos, M. Dévora-Pajares +63

We report two warm Earth-sized exoplanets orbiting the close binary TOI-2267 (M5+M6, separation ~8 au). Data from TESS and ground-based facilities confirm the planets, but we canno…

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…

TOI-6324b: An Earth-Mass Ultra-Short-Period Planet Transiting a Nearby M Dwarf

Rena A. Lee, Fei Dai, Andrew W. Howard +71

We report the confirmation of TOI-6324 b, an Earth-sized (1.059 0.041 R) ultra-short-period (USP) planet orbiting a nearby (20 pc) M dwarf. Using the newly com…

Updated Mass, Eccentricity, and Tidal Heating Constraints for the Earth-sized Planet LP 791-18 d

Michael Greklek-McKeon, Heather A. Knutson, W. Garrett Levine +5

LP 791-18 d is a temperate Earth-sized planet orbiting a late M dwarf, surrounded by an interior super-Earth (LP 791-18 b, = 1.2 , days) and an exterior…
