TOI-283 b: A transiting mini-Neptune in a 17.6-day orbit discovered with TESS and ESPRESSO

F. Murgas, E. Pallé, A. Suárez Mascareño +51

Super-Earths and mini-Neptunes are missing from our Solar System, yet they appear to be the most abundant planetary types in our Galaxy. A detailed characterization of key planets…

HD 21520 b: a warm sub-Neptune transiting a bright G dwarf

Molly Nies, Ismael Mireles, François Bouchy +49

We report the discovery and validation of HD 21520 b, a transiting planet found with TESS and orbiting a bright G dwarf (V=9.2, K, $R_{\star} = 1.04\pm 0.02…

Revised Architecture and Two New Super-Earths in the HD 134606 Planetary System

Zhexing Li, Stephen R. Kane, Timothy D. Brandt +15

Multi-planet systems exhibit a diversity of architectures that diverge from the solar system and contribute to the topic of exoplanet demographics. Radial velocity (RV) surveys for…

High-Resolution Imaging of a TESS Control Sample: Verifying a Deficit of Close-In Stellar Companions to Exoplanet Host Stars

Colin Littlefield, Steve B. Howell, David R. Ciardi +6

The large number of exoplanets discovered with the Transiting Exoplanet Survey Satellite (TESS) means that any observational biases from TESS could influence the derived stellar mu…

TOI-1801 b: A temperate mini-Neptune around a young M0.5 dwarf

M. Mallorquín, E. Goffo, E. Pallé +79

We report the discovery, mass, and radius determination of TOI-1801 b, a temperate mini-Neptune around a young M dwarf. TOI-1801 b was observed in TESS sectors 22 and 49, and the a…
