Title: Unlocking The Asteroseismic Potential Of Delta Scuti Stars With TESS And Song

PI: Hey, Daniel - University Of Hawaii (Manoa)

Type: SMALL

Summary: One of the breakthroughs in stellar astrophysics enabled by TESS during its prime mission was the discovery of high-frequency delta Scuti stars with regular frequency spacings, paving the way for modeling akin to less massive solar-like oscillators. However, most of these stars still show complex frequency patterns, and many modes remain unidentified. Ground-based radial velocity have a long tradition for being used to perform mode identification via line-profile variations. We propose to perform the first simultaneous RV observations of a high-frequency delta Scuti star observed by TESS using the SONG network of 1-m class telescopes. The observations are expected to enable a complete mode identification in delta Scuti for the first time, unlocking asteroseismology for this class of stars.
