Using numerical models of bow shocks to investigate the circumstellar medium of massive stars

, 2014
Many massive stars travel through the interstellar medium at supersonic speeds. As a result they form bow shocks at the interface between the stellar wind.

The Hidden Clumps in VY CMa Uncovered by the Atacama Large Millimeter/submillimeter Array

The Astronomical Journal
The red hypergiant VY CMa is famous for its very visible record of high-mass-loss events. Recent CO observations with the Atacama Large Millimeter/submillimeter Array (ALMA) revealed three previously unknown large-scale outflows (Singh et al).

Red Supergiant Mass Loss and Mass-Loss Rates

Galaxies
This review discusses the causes, nature, importance and observational evidence of mass loss by red supergiants. It arrives at the perception that mass loss finds its origin in the gravity which makes the star a star in the first place, and is a ...

Red supergiant stars in binary systems

Astronomy & Astrophysics
Red supergiant (RSG) stars represent the final evolutionary phase of the majority of massive stars and hold a unique role in testing the physics of stellar models. Eighty-eight RSGs in the Small Magellanic Cloud (SMC) were recently found to have an ultraviolet (UV) excess, which was attributed to a B-type companion.

The Red Supergiant Progenitor of the Type II Supernova 2024abfl

The Astrophysical Journal Letters
Linkage between core-collapse supernovae and their progenitors is not fully understood and ongoing effort of searching and identifying the progenitors is needed.

Radial Velocity and Astrometric Evidence for a Close Companion to Betelgeuse

The Astrophysical Journal
We examine a century of radial velocity, visual magnitude, and astrometric observations of the nearest red supergiant, Betelgeuse, in order to reexamine the century-old assertion that Betelgeuse might be a spectroscopic binary.
