The 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...
متن کاملType Ia supernovae and the 12C+12C reaction rate
Context. Even if the 12C+12C reaction plays a central role in the ignition of type Ia supernovae (SNIa), the experimental determination of its cross-section at astrophysically relevant energies (E 2 MeV) has never been made. The profusion of resonances throughout the measured energy range has led to speculation that there is an unknown resonance at E0 ∼ 1.5 MeV possibly as strong as the one mea...
متن کاملThe Rate of Type Ia Supernovae in Nearby Dwarf Galaxies
We used the Robotic Optical Transient Search Experiment (ROTSE-III) astrophysical transient survey to determine the rate of type Ia supernovae (SNe Ia) in dwarf galaxies within a radius of 310 Mpc. The rate is inferred from the SNe Ia sample discovered by ROTSE-III and a Monte Carlo simulation that estimates the ROTSE-III SNe Ia detection efficiency. Assuming that the rate of SNe Ia is the same...

Type Ia Supernovae
Type Ia Supernovae are in many aspects still enigmatic objects. Their observational and theoretical exploration is in full swing, but we still have plenty to learn about these explosions. Recent years have already witnessed a bonanza of supernova observations. The increased samples from dedicated searches have allowed the statistical investigation of Type Ia Supernovae as a class. The observati...
