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…
Discovery of a new transitional type of evolved massive stars with hard ionizing flux
Andreas A. C. Sander, Roel R. Lefever, Joris Josiek +12
Wolf-Rayet (WR) stars are the evolved descendants of the most massive stars and show emission-line dominated spectra formed in their powerful stellar winds. Marking the final evolu…
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…
Fifty Years of CAK
Jorick S. Vink
We present a new framework for massive star evolution that is no longer driven by Dutch or other mass-loss rate Recipes, but which take the physics of Gamma or L/M dependent mass l…
