VaTEST. II. Statistical Validation of 11 TESS-detected Exoplanets Orbiting K-type Stars
The Astronomical Journal, 2023 NASA’s Transiting Exoplanet Survey Satellite (TESS) is an all-sky survey mission designed to find transiting exoplanets orbiting nearby bright stars. It has identified more than 329 transiting exoplanets, and almost 6000 candidates remain unvalidated.
