Helium stars as supernova progenitors
Roni Waldman, Lev R. Yungelson, Zalman Barkat
We follow the evolution of helium stars of initial mass , and show that they undergo off-center carbon burning, which leaves behind ${\mathbf \sim 0.01 M_\odot…
Carbon-poor stellar cores as supernova progenitors
Roni Waldman, Zalman Barkat
Exploring stellar models which ignite carbon off-center (in the mass range of about 1.05 - 1.25 Msun, depending on the carbon mass fraction) we find that they may present an intere…
The Evolution of Low Mass Helium Stars towards Supernova Type I Explosion
Roni Waldman, Zalman Barkat
We explore the hypothesis, that helium stars in a certain mass range can evolve to a carbon core explosion similar to what is widely accepted as an explanation for the SN I phenome…
The Role of Kinetic Energy Flux in the Convective Urca Process
J. Stein, Z. Barkat, J. C. Wheeler
The previous analysis of the convective Urca neutrino loss process in degenerate, convective, quasi-static, carbon-burning cores by Barkat and Wheeler omitted specific consideratio…
