Optical Signatures of Circumstellar Interaction in Type Iip Supernovae
We propose new diagnostics for circumstellar interaction in Type IIP supernovae (SNe IIP) by the detection of high velocity (HV) absorption features in Hα and He I 10830 Å lines during the photospheric stage. To demonstrate the method, we compute the ionization and excitation of H and He in supernova ejecta taking into account time-dependent effects and X-ray irradiation. We find that the inter...
متن کاملThe Progenitors of Type Ia Supernovae
Type Ia supernovae (SNe Ia) occur in both old, passive galaxies and active, star-forming galaxies. This fact, coupled with the strong dependence of SN Ia rate on star formation rate, suggests that SNe Ia form from stars with a wide range of ages. Here we show that the rate of SN Ia explosions is about 1% of the stellar death rate, independent of star formation history. The dependence of SN Ia r...
متن کاملSeeking the progenitors of Type Ia Supernovae
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 results they have led to. The conclusion is that, as of today, we have reasonable guesses but none of them has yet been proven by direct observations.
متن کاملThe Progenitors of Subluminous Type Ia Supernovae
We find that spectroscopically peculiar subluminous SNe Ia come from an old population. Of the sixteen subluminous SNe Ia known, ten are found in E/S0 galaxies, and the remainder are found in early-type spirals. The probability that this is a chance occurrence is only 0.2%. The finding that subluminous SNe Ia are associated with an older stellar population indicates that for a sufficiently larg...
