Alternate Names

TOI-6101, TYC 5426-2934-1

Star likely matches with TYC 5426-2934-1, transiting exoplanet host independently detected by Ross et al. (2024) as TOI-6101.01. Hence the latter designation should be regarded as primary.
Schanche et al. (2025) confirm WASP-149 as exoplanet host and report a candidate companion star 7.8 arcseconds away (1653 AUs at 212 pc), likely an M dwarf.
