KPD 1930 + 2752 – a candidate Type Ia supernova progenitor
We present spectra of the pulsating sdB star KPD 1930+2752 which confirm that this star is a binary. The radial velocities measured from the Hα and HeI 6678Å spectral lines vary sinusoidally with the same period (2 h 17 m) as the ellipsoidal variability seen byBilì eres et al. (2000). The amplitude of the orbital motion (349.3±2.7 km s −1) combined with the canonical mass for sdB stars (0.5M ⊙)...
متن کاملType-Ia Supernova Rates and the Progenitor Problem: A Review
The identity of the progenitor systems of type-Ia supernovae (SNe Ia) is a major unsolved problem in astrophysics. SN Ia rates are providing some striking clues. We review the basics of SN rate measurement, preach about some sins of SN rate measurement and analysis, and illustrate one of these sins with an analogy about Martian scientists. We review the recent progress in measuring SN Ia rates ...
متن کاملThe Type Ia Supernova
We present the rst measurement of the rate of Type Ia super-novae at high redshift. The result is derived using a large subset of data from the Supernova Cosmology Project as described in more detail at this meeting by Perlmutter et al. (1996). We present our methods for estimating the numbers of galaxies and the number of solar luminosities to which the survey is sensitive, the supernova detec...
متن کاملThe Type Ia Supernova Rate
We explore the idea that the Type Ia supernovae (SNe Ia) rate is made up of two components: a prompt piece that is proportional to the star formation rate (SFR) and an extended piece that is proportional to the total stellar mass. We fit the parameters of this model to the local observations of Mannucci and collaborators and then study its impact on three important problems. On cosmic scales, t...
متن کاملType Ia Supernova Light Curves
The diversity of Type Ia supernova (SN Ia) photometry is explored using a grid of 130 one-dimensional models. It is shown that the observable properties of SNe Ia resulting from Chandrasekhar-mass explosions are chiefly determined by their final composition and some measure of “mixing” in the explosion. A grid of final compositions is explored including essentially all combinations of Ni, stabl...
