Dynamically consistent analysis of Galactic WN4b stars
Roel R. Lefever, Andreas A. C. Sander, Matheus Bernini-Peron +6
Many Wolf-Rayet (WR) stars have optically thick winds that cloak the hydrostatic layers of the underlying star. In these cases, traditional spectral analysis methods are plagued by…
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…
X-Shooting ULLYSES: Massive stars at low metallicity. IV. Spectral analysis methods and exemplary results for O stars
A. A. C. Sander, J. -C. Bouret, M. Bernini-Peron +26
CONTEXT: The spectral analysis of hot, massive stars is a fundamental astrophysical method to obtain their intrinsic properties and their feedback. Quantitative spectroscopy for ho…
Binarity at LOw Metallicity (BLOeM): a spectroscopic VLT monitoring survey of massive stars in the SMC
T. Shenar, J. Bodensteiner, H. Sana +74
Surveys in the Milky Way and Large Magellanic Cloud revealed that the majority of massive stars will interact with companions during their lives. However, knowledge of the binary p…
