A Hot Saturn Orbiting an Oscillating Late Subgiant Discovered by TESS

Jonathan Gagné, J.-D. do Nascimento, Andrés Jordán, A. Mazumdar et autres

We present the discovery of HD 221416 b, the first transiting planet identified by the Transiting Exoplanet Survey Satellite (TESS) for which asteroseismology of the host star is possible. HD 221416 b (HIP 116158, TOI-197) is a bright (V = 8.2 mag), …

Validation of 13 Hot and Potentially Terrestrial TESS Planets

Steven Giacalone, Courtney D. Dressing, Christina Hedges, Veselin B. Kostov et autres

Abstract The James Webb Space Telescope will be able to probe the atmospheres and surface properties of hot, terrestrial planets via emission spectroscopy. We identify 18 potentially terrestrial planet candidates detected by the Transiting Exoplanet Survey Satellite (TESS) that would make ideal …

A multi-planetary system orbiting the early-M dwarf TOI-1238

E. González-Álvarez, M. R. Zapatero Osorio, J. Sanz‐Forcada, J. A. Caballero et autres

Context. The number of super-Earth and Earth-mass planet discoveries has increased significantly in the last two decades thanks to the Doppler radial velocity and planetary transit observing techniques. Either technique can detect planet candidates on its own, but the power of a …

A multi-planetary system orbiting the early-M dwarf TOI-1238

E. González-Álvarez, M. R. Zapatero Osorio, J. Sanz‐Forcada, J. A. Caballero et autres

Two transiting planet candidates with super-Earth radii around the nearby K7--M0 dwarf star TOI-1238 were announced by TESS. We aim to validate their planetary nature using precise radial velocities (RV) taken with the CARMENES spectrograph. We obtained 55 CARMENES RV data that …

TESS Delivers Five New Hot Giant Planets Orbiting Bright Stars from the Full-frame Images

Joseph E. Rodriguez, Samuel N. Quinn, George Zhou, Andrew Vanderburg et autres

Abstract We present the discovery and characterization of five hot and warm Jupiters—TOI-628 b (TIC 281408474; HD 288842), TOI-640 b (TIC 147977348), TOI-1333 b (TIC 395171208, BD+47 3521A), TOI-1478 b (TIC 409794137), and TOI-1601 b (TIC 139375960)—based on data from NASA’s Transiting …
