Grids of stellar models with rotation: V. Models from 1.7 to 120 Msun at zero metallicity
Laura J. Murphy, Jose H. Groh, Sylvia Ekstrom +10
Understanding the nature of the first stars is key to understanding the early universe. With new facilities such as JWST we may soon have the first observations of the earliest ste…
Coupling thermal evolution of planets and hydrodynamic atmospheric escape in MESA
Daria Kubyshkina, Aline A. Vidotto, Luca Fossati +1
The long-term evolution of hydrogen-dominated atmospheres of sub-Neptune-like planets is mostly controlled by two factors: a slow dissipation of the gravitational energy acquired a…
Is GW190521 the merger of black holes from the first stellar generations?
Eoin J. Farrell, Jose H. Groh, Raphael Hirschi +5
GW190521 challenges our understanding of the late-stage evolution of massive stars and the effects of the pair-instability in particular. We discuss the possibility that stars at l…
SNAPSHOT: Connections between Internal and Surface Properties of Massive Stars
Eoin Farrell, Jose Groh, Georges Meynet +3
We introduce SNAPSHOT, a technique to systematically compute stellar structure models in hydrostatic and thermal equilibrium based on 3 structural properties - core mass $M_{\rm co…
The possible disappearance of a massive star in the low metallicity galaxy PHL 293B
Andrew Allan, Jose Groh, Andrea Mehner +4
We investigate a suspected very massive star in one of the most metal-poor dwarf galaxies, PHL~293B. Excitingly, we find the sudden disappearance of the stellar signatures from our…
The Uncertain Masses of Progenitors of Core Collapse Supernovae and Direct Collapse Black Holes
Eoin Farrell, Jose Groh, Georges Meynet +1
We show that it is not possible to determine the final mass of a red supergiant (RSG) at the pre-supernova (SN) stage from its luminosity and effective temperatur…
