THE DELAY TIME DISTRIBUTION OF TYPE Ia SUPERNOVAE AND THE SINGLE DEGENERATE MODEL
We present a theoretical delay time distribution (DTD) of Type Ia supernovae on the basis of our new evolutionary models of single degenerate (SD) progenitor systems. Our model DTD has almost a featureless power law shape (∝ t−n with n ≈ 1) for the delay time from t ∼ 0.1 to 10 Gyr. This is in good agreement with the recent direct measurement of DTD. The observed featureless property of the DTD...
متن کاملWhy Are Radio-Galaxies Prolific Producers of Type Ia Supernovae?
An analysis of SNIa events in early type galaxies from the Cappellaro et al. (1999) database provides conclusive evidence that the rate of type Ia Supernovae (SNe) in radio-loud galaxies is about 4 times higher than the rate measured in radio-quiet galaxies, i.e. SNIa-rate(radio− loud galaxies) = 0.43 −0.14h 2 75 SNu as compared to SNIa-rate(radio− quiet galaxies) = 0.11 −0.03h 2 75 SNu. The ac...
متن کاملSpectroscopically Peculiar Type Ia Supernovae and Implications for Progenitors
In a recent paper Li et al. (2000) reported that 36% of 45 Type Ia supernovae discovered since 1997 in two volume–limited supernova searches were spectroscopically peculiar, and they suggested that because this peculiarity rate is higher than that reported for an earlier non–volume–limited observational sample by Branch et al. (1993), it is now more likely that SNe Ia are produced by more than ...
متن کاملThe single-degenerate channel for the progenitor of type Ia supernovae with different metallicities
The single-degenerate channel for the progenitors of type Ia supernovae (SNe Ia) are currently accepted, in which a carbon-oxygen white dwarf (CO WD) accretes hydrogen-rich material from its companion, increases its mass to the Chandrasekhar mass limit, and then explodes as a SN Ia. Incorporating the prescription of Hachisu et al. (1999a) for the accretion efficiency into Eggleton’s stellar evo...
متن کاملCosmological constraints from type ia supernovae peculiar velocity measurements.
We detect the correlated peculiar velocities of nearby type Ia supernovae (SNe), while highlighting an error in some of the literature. We find sigma8 = 0.79 +/- 0.22 from SNe, and examine the potential of this method to constrain cosmological parameters in the future. We demonstrate that a survey of 300 low-z SNe (such as the nearby SNfactory) will underestimate the errors on w by approximatel...
