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…

2D unified atmosphere and wind simulations for a grid of O-type stars

Nicolas Moens, Dwaipayan Debnath, Olivier Verhamme +4

The atmospheres of massive O-type stars (O stars) are dynamic, turbulent environments resulting from radiatively driven instabilities over the iron bump, located slightly beneath t…

Mass loading of outflows from evolving Young Massive Clusters

C. J. K. Larkin, C. Hawcroft, J. Mackey +3

Feedback from Young Massive Clusters (YMCs) is an important driver of galaxy evolution. In the first few Myr, mechanical feedback is dominated by collective effects of the massive…

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…

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…

Improving 1D stellar atmosphere models with insights from multi-dimensional simulations II. 1D versus 3D hydrodynamically consistent model comparison for WR stars

G. González-Torà, A. A. C. Sander, N. Moens +8

Classical Wolf-Rayet (cWR) stars are evolved massive stars that have lost most of their H envelope and exhibit dense, extended atmospheres with strong, line-driven winds. Accuratel…
