Calibrating Eruptive Mass Loss in Red Supergiants with Local Group Data
Shelley J. Cheng, Charlie Conroy, Jared A. Goldberg
We calibrate a physically motivated, super-Eddington eruptive mass-loss prescription for red supergiants (RSGs) using Local Group stellar populations. Building on MESA models that…
A Model for Eruptive Mass Loss in Massive Stars
Shelley J. Cheng, Jared A. Goldberg, Matteo Cantiello +3
Eruptive mass loss in massive stars is known to occur, but the mechanism(s) are not yet well-understood. One proposed physical explanation appeals to opacity-driven super-Eddington…
Detailed Characterization of Heartbeat Stars and their Tidally Excited Oscillations
Shelley J. Cheng, Jim Fuller, Zhao Guo +2
Heartbeat stars are a class of eccentric binary stars with short-period orbits and characteristic "heartbeat" signals in their light curves at periastron, caused primarily by tidal…
Interacting Young M-dwarfs in Triple System -- Par 1802 Binary System Case Study
Shelley J. Cheng, Alec M. Vinson, Smadar Naoz
The binary star Par 1802 in the Orion Nebula presents an interesting puzzle in the field of stellar dynamics and evolution. Binary systems such as Par 1802 are thought to form from…
