Evidence for stellar mergers of evolved massive binaries: blue supergiants in the Large Magellanic Cloud
Athira Menon, Andrea Ercolino, Miguel A. Urbaneja +8
Blue supergiants are the brightest stars in their host galaxies and yet their evolutionary status has been a long-standing problem in stellar astrophysics. In this pioneering work,…
Betelgeuse as a Merger of a Massive Star with a Companion
Sagiv Shiber, Emmanouil Chatzopoulos, Bradley Munson +1
We investigate the merger between a 16 solar mass star, on its way to becoming a red supergiant (RSG), and a 4 solar mass main-sequence companion. Our study employs three-dimension…
Betelgeuse: a Review
J. Craig Wheeler, Emmanouil Chatzopoulos
Betelgeuse has fascinated people since they first looked at the sky. Here we present a contemporary summary of the observations and theory that lead to our understanding of Betelge…
Monte Carlo Radiation Transport for Astrophysical Transients Powered by Circumstellar Interaction
Gururaj A. Wagle, Emmanouil Chatzopoulos, Ryan Wollaeger +1
In this paper, we introduce \texttt{SuperLite}, an open-source Monte Carlo radiation transport code designed to produce synthetic spectra for astrophysical transient phenomena affe…
