An Earth-sized Planet on the Verge of Tidal Disruption

Kavli Affiliate: Roland Vanderspek | First 5 Authors: Fei Dai, Andrew W. Howard, Samuel Halverson, Jaume Orell-Miquel, Enric Palle | Summary: TOI-6255~b (GJ 4256) is an Earth-sized planet (1.079$pm0.065$ $R_oplus$) with an orbital period of only 5.7 hours. With the newly commissioned Keck Planet Finder (KPF) and CARMENES spectrographs, we determined the planet’s mass to […]

A transiting multi-planet system in the 61 million year old association Theia 116

Kavli Affiliate: Sara Seager | First 5 Authors: Sydney Vach, George Zhou, Chelsea X. Huang, Andrew W. Mann, Madyson G. Barber | Summary: Observing and characterizing young planetary systems can aid in unveiling the evolutionary mechanisms that sculpt the mature exoplanet population. As an all-sky survey, NASA’s Transiting Exoplanet Survey Satellite (TESS) has expanded the […]

GJ 238 b: A 0.57 Earth Radius Planet Orbiting an M2.5 Dwarf Star at 15.2 pc

Kavli Affiliate: Sara Seager | First 5 Authors: Evan Tey, Avi Shporer, Zifan Lin, Keivan G. Stassun, Jack J. Lissauer | Summary: We report the discovery of the transiting planet GJ 238 b, with a radius of $0.566pm0.014$ R$_{oplus}$ ($1.064pm0.026$ times the radius of Mars) and an orbital period of 1.74 day. The transit signal […]
