TESS Data Used to Create Largest-Ever Catalog of Stellar Rotation Periods for Over a Million Stars

A recent study has leveraged data from the Transiting Exoplanet Survey Satellite (TESS) to build the largest catalog of stellar rotation periods ever created, covering over a million stars. Stellar rotation is a key factor in understanding stellar evolution and exoplanet science. TESS, primarily designed to discover exoplanets by detecting dips in starlight, has provided full-sky coverage that enabled this massive catalog of rotation periods.
