Convective core entrainment in 1D main sequence stellar models
L. J. A. Scott, R. Hirschi, C. Georgy +5
3D hydrodynamics models of deep stellar convection exhibit turbulent entrainment at the convective-radiative boundary which follows the entrainment law, varying with boundary penet…
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…
Relative Importance of Convective Uncertainties in Massive Stars
Etienne A. Kaiser, Raphael Hirschi, W. David Arnett +3
In this work, we investigate the impact of uncertainties due to convective boundary mixing (CBM), commonly called `overshoot', namely the boundary location and the amount of mixing…
The Formation of a 70 Msun Black Hole at High Metallicity
K. Belczynski, R. Hirschi, E. A. Kaiser +7
A 70Msun BH was discovered in Milky Way disk in a long period and almost circular detached binary system (LB-1) with a high metallicity 8Msun B star companion. Current consensus on…
3D Simulations and MLT: I. Renzini's Critique
W. David Arnett, Casey Meakin, Raphael Hirschi +5
Renzini (1987) wrote an influential critique of mixing-length theory (MLT) as used in stellar evolution codes, and concluded that three-dimensional (3D) fluid dynamical simulations…
Relative Importance of Convective Uncertainties
Etienne A. Kaiser, Raphael Hirschi, W. David Arnett +3
Convection plays a key role in the evolution of stars due to energy transport and mixing of composition. Despite its importance, this process is still not well understood. One long…
