Can Wolf-Rayet stars be the missing ingredient to explain high-z He II ionizing radiation?

G. González-Torà, A. A. C. Sander, E. Egorova +7

Classical Wolf-Rayet (WR) stars are hot, massive stars with depleted hydrogen. At low metallicities (Z), WN3-type WR stars have relatively thin winds and are major sources of ioniz…

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…

Exploring the connection between atmosphere models and evolution models of very massive stars

Joris Josiek, Andreas A. C. Sander, Matheus Bernini-Peron +6

Very massive stars (VMS) dominate the light of young stellar populations and are sources of intense stellar feedback. Their evolution is mainly driven by strong wind mass loss, yet…

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…

Resolving the baryon assymmetry with RATS

J. Josiek, M. Bernini-Peron, G. González-Torà +2

Current leading theories of physics such as the Big Bang, the standard model of particle physics, and general relativity suggest that the universe should contain an equal amount of…

Extremely iron-poor O-type stars in the Magellanic Bridge

E. C. Schösser, V. Ramachandran, A. A. C. Sander +7

To study stars analogous to those in the early Universe with redshift z > 3, we need to probe environments with low metallicities. Until recently, massive O-type stars with metalli…
