Asteroseismology of extreme horizontal branch (subdwarf B) stars with TESS data

During its primary mission, TESS observed over 550 of our target Subdwarf B (sdB) stars in short-cadence mode, from which we anticipate about 150 will be pulsating. This will allow an ensemble analysis of these interesting extreme horizontal branch stars, probing their interior structures. Combined with other all-sky surveys, such as GAIA, TESS data allow ensemble analyses of extreme horizontal branch stars, allowing us to probe the structure of helium-fusing cores.
