A grid of fast-rotating, chemically-homogeneous, supernova and/or long-GRB progenitors
M. Renzo, O. Gottlieb, H. S. Chan +6
The understanding of the mechanism(s) by which massive stars collapse and possibly explode is rapidly maturing. Uncertainties in the structure of the stellar core at the onset of c…
Accretion of Primordial Black Holes in Stellar Interiors
Matteo Cantiello, Ore Gottlieb, Cameron Norton +2
We study spherical accretion onto primordial black holes (PBHs) embedded in the core of a solar-type star. We compute the radiative efficiency self-consistently for the first time…
The Life and Death of Stars That Capture Primordial Black Holes
Ore Gottlieb, Matteo Cantiello, Cameron Norton +2
Primordial black holes (PBHs) in the asteroid mass window () remain viable dark matter candidates and can be captured by stars. We develop the first globa…
Progenitor with small reaction networks should not be used as initial conditions for core collapse
M. Renzo, J. A. Goldberg, A. Grichener +2
Core collapse initial conditions are a bottleneck in understanding the explosion mechanism(s) of massive stars. Stellar evolution codes struggle after carbon burning, and either st…
