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…
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…
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-…
Tidally Heated Sub-Neptunes, Refined Planetary Compositions, and Confirmation of a Third Planet in the TOI-1266 System
Michael Greklek-McKeon, Shreyas Vissapragada, Heather A. Knutson +38
TOI-1266 is a benchmark system of two temperate ( 450 K) sub-Neptune-sized planets orbiting a nearby M dwarf exhibiting a rare inverted architecture with a larger interior plane…
Detection of an Atmospheric Outflow from the Young Hot Saturn TOI-1268b
Jorge Pérez González, Michael Greklek-McKeon, Shreyas Vissapragada +4
Photoevaporative mass-loss rates are expected to be highest when planets are young and the host star is more active, but to date there have been relatively few measurements of mass…
Helium in the Extended Atmosphere of the Warm Super-Puff TOI-1420b
Shreyas Vissapragada, Michael Greklek-McKeon, Dion Linssen +11
Super-puffs are planets with exceptionally low densities (~g~cm) and core masses (). Many lower-mass () super…
