Seeking the Progenitors of Type Ia Supernovae
Ferdinando Patat
The nature of the progenitor system[s] of Type Ia Supernovae is still unclear. In this contribution I review the projects that have been undertaken to answer this question and the…
Constraints on Type Ib/c and GRB Progenitors
C. L. Fryer, P. A. Mazzali, J. Prochaska +14
Although there is strong support for the collapsar engine as the power source of long-duration gamma-ray bursts (GRBs), we still do not definitively know the progenitor of these ex…
The Rates of Hypernovae and Gamma-Ray Bursts: Implications for their Progenitors
Ph. Podsiadlowski, P. A. Mazzali, K. Nomoto +2
A critical comparison of estimates for the rates of hypernovae (HNe) and gamma-ray bursts (GRBs) is presented. Within the substantial uncertainties, the estimates are shown to be q…
Low-Metallicity Inhibition of Type Ia Supernovae and Galactic and Cosmic Chemical Evolution
Chiaki Kobayashi, Takuji Tsujimoto, Ken'ich Nomoto +2
We introduce a metallicity dependence of Type Ia supernova (SN Ia) rate into the Galactic and cosmic chemical evolution models. In our SN Ia progenitor scenario, the accreting whit…
