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…
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…
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…
