A new study led by a Georgia State University astronomy graduate student is a major step forward in the search for stars that could host Earth-like planets that may prove […]

TOI 2093 c in the context of exoplanets with known mass and radius with errors smaller than 12%. Left panel: Planetary mass and radius, with theoretical models from Zeng et al. (2016) (see Sect. 4). Right panel: Escape velocity against equilibrium temperature (planetary data from the NASA exoplanets database). TOI 2093 b is included assuming ib ≳ 50◦, with the planet radius calculated for a bulk density between 0.5 and 10 g cm−3 , with errors shown as a red band. -- astro-ph.EP

A Planetary System With A Sub-Neptune Planet In The Habitable Zone Of TOI-2093

by Keith CowingOctober 2, 2025October 2, 2025

Aims. We aim to confirm and measure the mass of the transiting planet candidate around the K5V star TOI-2093, previously announced by the Transiting Exoplanet Survey Satellite (TESS) project.
