Hydrodynamical mass-loss rates for very massive stars II. New theoretical mass-loss predictions at solar metallicity (Z = 0.02)
Gautham N. Sabhahit, Jorick S. Vink, Andreas A. C. Sander
The paper presents a new theoretical prescription for mass loss in very massive stars, based on a large grid of hydrodynamically consistent wind models that capture the dependence…
On the Robustness of Bi-Stability Jump Predictions
Jorick S. Vink, Gautham N. Sabhahit, Andreas A. C. Sander
The bi-stability jump is a long-standing theoretical prediction of radiatively driven wind theory, associated with Fe IV/III recombination around T = 21000 - 25000 K. While most th…
Multi-Dimensional MHD simulations of young Core-Collapse Supernova Remnants
C. J. K. Larkin, J. Mackey, B. Reville +3
Supernova remnants (SNRs) play a central role in shaping the interstellar medium. Core-Collapse Supernova (CCSN) progenitors are massive stars, which produce a dense circumstellar…
Multi-dimensional, time-dependent approximate NLTE unified model atmospheres with winds for hot, massive stars
Dwaipayan Debnath, Jon O. Sundqvist, Nicolas Moens +3
Multi-dimensional unified model atmospheres with winds of massive stars have so far been studied under the assumption of equal flux, Planck, and energy weighted mean opacities, whi…
The complex dependencies of Wolf-Rayet winds -- Insights from detailed radiative transfer models
Andreas A. C. Sander, Roel R. Lefever, Gemma González-TorÃ
With their emission-line dominated spectra, the appearance of Wolf-Rayet stars is shaped by their strong stellar winds. Yet, the physical mechanisms behind their high mass loss hav…
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…
