The Effect of Donor Star Rejuvenation on Common Envelope Evolution
C. Landri, P. M. Ricker, M. Renzo +2
In close binary star systems, common envelope evolution may occur after a previous phase of mass transfer. Some isolated formation channels for double neutron star binaries suggest…

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…
