Radial Velocity Evidence for a Post-Mass-Transfer Massive Binary System NaSt1
Kittipong Wangnok, Samaporn Tinyanont, Ryan M. Lau +11
We present multi-epoch high-resolution optical spectroscopy () of the emission-line object NaSt1 to test its proposed binary nature, along with long-term multiba…
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 Buddy for Betelgeuse: Binarity as the Origin of the Long Secondary Period in Orionis
Jared A. Goldberg, Meridith Joyce, László Molnár
We predict the existence of Ori B, a low-mass companion orbiting Betelgeuse. This is motivated by the presence of a 2170-day Long Secondary Period (LSP) in Betelgeuse's lightcu…
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…
