Title: Pulsations And Disks Of Be Stars: Tracers Of Stellar Structure, Evolution, Pulsation-Driven Mass Loss, And Disk Physics

PI: Richardson, Noel - Embry-Riddle Aeronautical University

Type: SMALL

Summary: Be stars are near-critically rotating B stars that mechanically eject mass and form orbiting viscous 'decretion' disks about their equator. As such, they are valuable astrophysical laboratories for a variety of processes - most notably disk growth and dissipation, and rapid rotation and non-radial pulsations. We use TESS data to quantify their variability, such as pulsation-driven mass ejection and the dynamics of their disks. A ground-based time-series spectroscopic campaign contemporaneous with TESS observations is being pursued for ~200 Be stars. From spectra, the density, velocity, and temperature structure of circumstellar matter inferred. The processes leading to ejection of the disk is a key problem for Be stars, and an analysis of hundreds of such events will answer this question.
