# TESS Program G09177

Title: Extending The Hot Subdwarf Asteroseismic Census With TESS Cycle 9 Photometry

PI: Barlow, Brad - University Of North Carolina

Type: SMALL

Summary: We propose TESS Cycle 9 observations of known and candidate pulsating hot subdwarf stars to (i) extend baselines of known variables to unlock new asteroseismic science thresholds and (ii) discover entirely new hot subdwarf pulsators. Collectively, these light curves will enable detailed asteroseismic analyses probing helium-burning core masses, internal rotation profiles, and chemical stratification across a large sample of extreme horizontal branch stars. A subset of targets overlap with PLATO long-duration fields, providing complementary long-baseline coverage. An ancillary transit survey will search for planetary survivors of common envelope evolution. This program will improve our capacity to draw a statistically meaningful picture of this enigmatic stage of stellar evolution.
