We observed a second epoch for the TIC-231005575 system (Tmag = 12.06 and Teff=5500±85K ) with NGTS and a third epoch with Las Cumbres Observatory's telescope in South Africa to constrain the orbital period ( P=61.777d ). Subsequent radial velocity measurements with CORALIE revealed the transiting object has a mass of M2 = 0.128 ± 0.003 M☉, indicating the system is a G-M binary. The radius of the secondary is R2 = 0.154 ± 0.008 R☉ and is consistent with MESA models of stellar evolution to better than 1σ. Item URL in elib: | https://elib.dlr.de/137255/ |
