Clumping and X-Rays in cooler B supergiant stars
Matheus Bernini-Peron, Wagner L. F. Marcolino, Andreas A. C. Sander +6
B supergiants (BSGs) are evolved stars with effective temperatures between 10 to 30 kK and are important to understand massive star evolution. Located on the edge of the line-drive…
Very Massive Stars and Pair-Instability Supernovae: Mass-loss Framework for low Metallicity
Gautham N. Sabhahit, Jorick S. Vink, Andreas A. C. Sander +1
Very massive stars (VMS) up to 200-300 have been found in the Local Universe. If they would lose little mass they produce intermediate-mass black holes or pair-instabilit…
From Dust to Nanodust: Resolving Circumstellar Dust from the Colliding-Wind Binary Wolf-Rayet (WR) 140
Ryan M. Lau, Jason Wang, Matthew J. Hankins +17
Wolf-Rayet (WR) 140 is the archetypal periodic dust-forming colliding-wind binary that hosts a carbon-rich WR (WC) star and an O-star companion with an orbital period of 7.93 years…
Bringing Stellar Evolution & Feedback Together: Summary of proposals from the Lorentz Center Workshop, 2022
Sam Geen, Poojan Agrawal, Paul A. Crowther +34
Stars strongly impact their environment, and shape structures on all scales throughout the universe, in a process known as ``feedback''. Due to the complexity of both stellar evolu…
