Jets Identify the Progenitors of Type Ia Supernovae ?

چکیده
We use the fact that a Type Ia supernova has been serendipitously discovered near the jet of the active galaxy 3C 78 to examine the question of whether jets can enhance accretion onto white dwarfs. One interesting outcome of such a jet-induced accretion process is an enhanced rate of novae in the vicinity of jets. We present results of observations of the jet in M87 which appear to have indeed discovered 11 novae in close proximity to the jet. We show that a confirmation of the relation between jets and novae and Type Ia supernovae can finally identify the elusive progenitors of Type Ia supernovae.

The Effect of Different Type Ia Supernova Progenitors on Galactic Chemical Evolution
Aims. Our aim is to show how different hypotheses about Type Ia supernova progenitors can affect Galactic chemical evolution. Supernovae Ia, in fact, are believed to be the main producers of Fe and the timescale with which Fe is restored into the interstellar medium depends on the assumed supernova progenitor model. This is a way of selecting the right progenitor model for supernovae Ia, a stil...
متن کاملSearch for Double Degenerate Progenitors of Supernovae Type Ia with Spy
We report on a large survey for double degenerate (DD) binaries as potential progenitors of type Ia supernovae with the UVES spectrograph at the ESO VLT (ESO SN Ia Progenitor surveY – SPY).
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 کاملThe rate and the origin of type Ia supernovae in radiogalaxies
An analysis of type Ia supernova (SNIa) events in early type galaxies from Evans et al. (1989) database provides strong evidence that the rate of type Ia supernovae (SNe) in radio-loud galaxies is about 6 times higher than the rate measured in radio-quiet galaxies, i.e. SNIarate(radio − loud galaxies) = 0.47 −0.15 h 2 50 SNe per century and per 10 L ⊙ (SNU) as compared to SNIa-rate(radio− quiet...
