The physical origin of the maximum stellar size
Gautham N. Sabhahit, Jorick S. Vink
One might expect the most massive stars to also be the largest by size, yet they are not, and this has puzzled astronomers for decades. The Eddington limit sets an upper bound to s…
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 evolutionary pathways and ultimate fates of very massive stars are governed primarily by mass loss through radiatively driven winds. We present a new theoretical mass-loss pres…
The winds of OBA hypergiants and luminous blue variables: Dynamically-consistent atmosphere models reveal multiple wind regimes
Matheus Bernini-Peron, Andreas A. C. Sander, Gautham N. Sabhahit +3
OBA hypergiants (OBAHGs) are evolved massive stars with notable wind features in their optical spectrum. Located at the cool edge of the line-driven wind regime, many are candidate…
