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…

Population synthesis of Thorne-Żytkow objects: Rejuvenated donors and unexplored progenitors in the common envelope formation channel
K. Nathaniel, A. Vigna-Gómez, A. Grichener +3
Context. Common envelope evolution of a massive star and a neutron star companion has two possible outcomes: formation of a short-period binary (a potential gravitational wave sour…

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…
