The TESS-Keck Survey. XXII. A sub-Neptune Orbiting TOI-1437
Daria Pidhorodetska, Emily A. Gilbert, Stephen R. Kane +40
Exoplanet discoveries have revealed a dramatic diversity of planet sizes across a vast array of orbital architectures. Sub-Neptunes are of particular interest; due to their absence…
The TESS-Keck Survey XXI: 13 New Planets and Homogeneous Properties for 21 Subgiant Systems
Ashley Chontos, Daniel Huber, Samuel K. Grunblatt +67
We present a dedicated transit and radial velocity survey of planets orbiting subgiant stars observed by the TESS Mission. Using nights on Keck/HIRES, we confirm and cha…
The TESS-Keck Survey. XII. A Dense 1.8 R Ultra-Short-Period Planet Possibly Clinging to a High-Mean-Molecular-Weight Atmosphere After the First Gyr
Ryan A. Rubenzahl, Fei Dai, Andrew W. Howard +39
The extreme environments of ultra-short-period planets (USPs) make excellent laboratories to study how exoplanets obtain, lose, retain, and/or regain gaseous atmospheres. We presen…
