BEBOP V. Homogeneous Stellar Analysis of Potential Circumbinary Planet Hosts

Alix V. Freckelton, Daniel Sebastian, Annelies Mortier +29

Planets orbiting binary systems are relatively unexplored compared to those around single stars. Detections of circumbinary planets and planetary systems offer a first detailed vie…

Investigating stellar activity through eight years of Sun-as-a-star observations

Baptiste Klein, Suzanne Aigrain, Michael Cretignier +11

Stellar magnetic activity induces both distortions and Doppler-shifts in the absorption line profiles of Sun-like stars. Those effects produce apparent radial velocity (RV) signals…

Gliese 12 b, A Temperate Earth-sized Planet at 12 Parsecs Discovered with TESS and CHEOPS

Shishir Dholakia, Larissa Palethorpe, Alexander Venner +33

We report on the discovery of Gliese 12 b, the nearest transiting temperate, Earth-sized planet found to date. Gliese 12 is a bright ( mag, mag) metal-poor M4V star…

TOI-837b is a Young Saturn-sized Exoplanet with a Massive 70 Core

Oscar Barragán, Haochuan Yu, Alix Violet Freckelton +10

We present an exhaustive photometric and spectroscopic analysis of TOI-837, a F9/G0 35 Myr young star, hosting a transiting exoplanet, TOI-837b, with an orbital period of 8.32d. Ut…

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…

Characterization of K2-167 b and CALM, a new stellar activity mitigation method

Zoë L. de Beurs, Andrew Vanderburg, Erica Thygesen +13

We report precise radial velocity (RV) observations of HD 212657 (= K2-167), a star shown by K2 to host a transiting sub-Neptune-sized planet in a 10 day orbit. Using Transiting Ex…
