Abstract

The Transiting Exoplanet Survey Satellite (TESS) has produced a large number of single transit event candidates which are being monitored by the Next Generation Transit Survey (NGTS). We observed a second epoch for the TIC-231005575 system (Tmag = 12.06, Teff =5500 ± 85 K) with NGTS and a third epoch with Las Cumbres Observatory's (LCO) telescope in South Africa to constrain the orbital period (P = 61.777 d). Subsequent radial velocity measurements with CORALIE revealed the transiting object has a mass of M2 =0.128 ± 0.003M⨀, indicating the system is a G-M binary. The radius of the secondary is R2 = 0.154 ±0.008R⨀ and is consistent with MESA models of stellar evolution to better than 1-σ.
