Stellar Expansion or Inflation?
Gautham N. Sabhahit, Jorick S. Vink
While stellar expansion after core-hydrogen exhaustion related to thermal imbalance has been documented for decades, the physical phenomenon of stellar inflation that occurs close…
X-Shooting ULLYSES: Massive stars at low metallicity VI. Atmosphere and mass-loss properties of O-type giants in the Small Magellanic Cloud
Frank Backs, S. A. Brands, A. de Koter +21
Mass loss through a stellar wind is an important physical process that steers the evolution of massive stars and controls the properties of their end-of-life products, such as the…
The Maximum Black Hole Mass at Solar Metallicity
Jorick S. Vink, Gautham N. Sabhahit, Erin R. Higgins
We analyse the current knowledge and uncertainties in detailed stellar evolution and wind modelling to evaluate the mass of the most massive stellar black hole (BH) at solar metall…
New Wolf-Rayet wind yields and nucleosynthesis of Helium stars
Erin R. Higgins, Jorick S. Vink, Raphael Hirschi +2
Strong metallicity-dependent winds dominate the evolution of core He-burning, classical Wolf-Rayet (cWR) stars, which eject both H and He-fusion products such as 14N, 12C, 16O, 19F…
Stellar Winds
Jorick S. Vink
Stellar winds form an integral part of astronomy. The solar wind affects Earth's magnetosphere, while the winds of hot massive stars are highly relevant for galactic feedback throu…
X-Shooting ULLYSES: Massive Stars at Low Metallicity
Jorick S. Vink, Paul Crowther, Alex Fullerton +20
The Hubble Space Telescope has devoted 500 orbits to observing 250 massive stars with low metallicity in the ultraviolet (UV) range within the framework of the ULLYSES program. The…
