Discovery of a new transitional type of evolved massive stars with hard ionizing flux
Andreas A. C. Sander, Roel R. Lefever, Joris Josiek +12
Wolf-Rayet (WR) stars are the evolved descendants of the most massive stars and show emission-line dominated spectra formed in their powerful stellar winds. Marking the final evolu…
Constraints on the progenitor and explosion of SN 2024ggi in harmony with pre-explosion detection and hydrodynamic simulations
Amar Aryan, Erin Higgins, Matt Nicholl +2
Supernova (SN) 2024ggi is a nearby Type II SN discovered by ATLAS, showing early flash-ionization features. The pre-explosion images reveal a red supergiant (RSG) progenitor with a…
The impact of wind mass loss on nucleosynthesis and yields of very massive stars at low metallicity
Erin R. Higgins, Jorick S. Vink, Raphael Hirschi +2
The chemical feedback from stellar winds in low metallicity (Z) environments is key for understanding the evolution of globular clusters and the early Universe. With disproportiona…
The black hole - pair instability boundary for high stellar rotation
Ethan R. J. Winch, Gautham N. Sabhahit, Jorick S. Vink +1
The Pair Instability (PI) boundary is crucial for understanding heavy merging Black Holes (BHs) and the second mass gap's role in galactic chemical evolution. So far, no works have…
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…
Predicting the Heaviest Black Holes below the Pair Instability Gap
Ethan R. J. Winch, Jorick S. Vink, Erin R. Higgins +1
Traditionally, the pair instability (PI) mass gap is located between 50\,and 130\,, with stellar mass black holes (BHs) expected to "pile up" towards the lower PI edge.…
Stellar Wind Yields of Very Massive Stars
Erin R. Higgins, Jorick S. Vink, Raphael Hirschi +2
The most massive stars provide an essential source of recycled material for young clusters and galaxies. While very massive stars (VMS, M>100M) are relatively rare compared to O st…
Very Massive Stars and Pair-Instability Supernovae: Mass-loss Framework for low Metallicity
Gautham N. Sabhahit, Jorick S. Vink, Andreas A. C. Sander +1
Very massive stars (VMS) up to 200-300 have been found in the Local Universe. If they would lose little mass they produce intermediate-mass black holes or pair-instabilit…
X-Shooting ULLYSES: massive stars at low metallicity. I. Project Description
Jorick S. Vink, A. Mehner, P. A. Crowther +78
Observations of individual massive stars, super-luminous supernovae, gamma-ray bursts, and gravitational-wave events involving spectacular black-hole mergers, indicate that the low…
Bringing Stellar Evolution & Feedback Together: Summary of proposals from the Lorentz Center Workshop, 2022
Sam Geen, Poojan Agrawal, Paul A. Crowther +34
Stars strongly impact their environment, and shape structures on all scales throughout the universe, in a process known as ``feedback''. Due to the complexity of both stellar evolu…
Stellar age determination in the Mass-Luminosity Plane
Erin R. Higgins, Jorick S. Vink
The ages of stars have historically relied on isochrone fitting of standardised grids of models. While these stellar models have provided key constraints on observational samples o…
The hydrogen clock to infer the upper stellar mass
Erin R. Higgins, Jorick S. Vink, Gautham N. Sabhahit +1
The most massive stars dominate the chemical enrichment, mechanical and radiative feedback, and energy budget of their host environments. Yet how massive stars initially form and h…
Mass-loss implementation and temperature evolution of very massive stars
Gautham N. Sabhahit, Jorick S. Vink, Erin R. Higgins +1
Very massive stars (VMS) dominate the physics of young clusters due to their ionising radiation and extreme stellar winds. It is these winds that determine their lifepaths until ex…
The Link between Hot and Cool Outflows
Jorick S. Vink, A. A. C. Sander, E. R. Higgins +1
The link between hot and cool stellar outflows is shown to be critical for correctly predicting the masses of the most massive black holes (BHs) below the so-called pair-instabilit…
The origin and impact of Wolf-Rayet-type mass loss
Andreas A. C. Sander, Jorick S. Vink, Erin R. Higgins +3
Classical Wolf-Rayet (WR) stars mark an important stage in the late evolution of massive stars. As hydrogen-poor massive stars, these objects have lost their outer layers, while st…
Superadiabaticity and the metallicity independence of the Humphreys-Davidson limit
Gautham N. Sabhahit, Jorick S. Vink, Erin R. Higgins +1
The Humphreys-Davidson (HD) limit sets the boundary between evolutionary channels of massive stars that either end their lives as red supergiants (RSGs) or as the hotter blue super…
Evolution of Wolf-Rayet stars as black hole progenitors
Erin R. Higgins, Andreas A. C. Sander, Jorick S. Vink +1
Evolved Wolf-Rayet stars form a key aspect of massive star evolution, and their strong outflows determine their final fates. In this study, we calculate grids of stellar models for…
Maximum Black Hole mass across Cosmic Time
Jorick S. Vink, Erin R. Higgins, Andreas A. C. Sander +1
At the end of its life, a very massive star is expected to collapse into a black hole. The recent detection of an 85 Msun black hole from the gravitational wave event GW 190521 app…
A theoretical investigation of the Humphreys-Davidson limit at high and low metallicity
