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…
The Driving of Hot Star Winds
Andreas A. C. Sander
In the regime of hot stars, winds were not seen as a common thing until the era of UV astronomy. Since we have access to the UV wavelength range, it has become clear that winds are…
Massive Stars in the Far and Extreme Ultraviolet
Andreas A. C. Sander
From the main sequence to their late evolutionary stages, massive stars spend most of their life as hot stars. Due to their high effective temperatures, the maximum of their emitte…
Investigating the impact of different velocity fields on the spectral appearance of Wolf-Rayet stars
Roel R. Lefever, Tomer Shenar, Andreas A. C. Sander +3
The emission line spectra of WR stars are often formed completely in the optically thick stellar wind. Hence, any assumption on the wind velocity law in a spectral analysis has a p…
