Hydrodynamical mass-loss rates for Very Massive Stars. I. Investigating the wind kink
Gautham N. Sabhahit, Jorick S. Vink, Andreas A. C. Sander
Radiation-driven winds are ubiquitous in massive stars, but in Very Massive Stars (VMSs), mass loss dominates their evolution, chemical yields, and ultimate fate. Theoretical predi…
Black Holes at high and low metallicity
Jorick S. Vink, Gautham N. Sabhahit, Ethan R. J. Winch
At the end of their lives the most massive stars collapse into black holes (BHs). The detection of an 85 BH from GW 190521 appeared to challenge the upper-mass limit im…
Minimum and maximum mass-luminosity relations for stripped stars
Gautham N. Sabhahit, Jorick S. Vink, Andreas A. C. Sander +1
Envelope stripping, whether through single-star wind mass loss or binary mass transfer, is a key evolutionary pathway for the formation of classical Wolf-Rayet stars and lower-mass…
Metal-poor single Wolf-Rayet stars: The interplay of optically thick winds and rotation
Lumen Boco, Michela Mapelli, Andreas A. C. Sander +7
The Small Magellanic Cloud (SMC) hosts 12 known Wolf-Rayet (WR) stars, seven of which are apparently single. Their formation is a challenge for current stellar evolution models bec…
Near-Eddington mass loss of hydrogen-rich Wolf-Rayet stars
Roel R. Lefever, Andreas A. C. Sander, Matheus Bernini-Peron +6
Context. Very massive clusters and regions of intense star formation such as the center of our Milky Way contain young, hydrogen-burning stars very close to the Eddington Limit. Fo…
The impact of wind mass loss on nucleosynthesis and yields of very massive stars at low metallicity
Erin R. Higgins, Jorick S. Vink, Raphael Hirschi +2
The chemical feedback from stellar winds in low metallicity (Z) environments is key for understanding the evolution of globular clusters and the early Universe. With disproportiona…
The black hole - pair instability boundary for high stellar rotation
Ethan R. J. Winch, Gautham N. Sabhahit, Jorick S. Vink +1
The Pair Instability (PI) boundary is crucial for understanding heavy merging Black Holes (BHs) and the second mass gap's role in galactic chemical evolution. So far, no works have…
Coupling hydrodynamics with comoving frame radiative transfer. III. The wind regime of early-type B hypergiants
M. Bernini-Peron, A. A. C. Sander, F. Najarro +8
Context. B hypergiants (BHGs) are important for understanding high-mass stellar evolution. While they are in a similar parameter space of B supergiants (BSGs), some BHGs are known…
A new mass estimate method with hydrodynamical atmospheres for very massive WNh stars
Gautham N. Sabhahit, Jorick S. Vink, Andreas A. C. Sander +4
Very massive stars with masses over 100 Msun are key objects in the Universe for our understanding of chemical and energetic feedback in the Universe, but their evolution and fate…
