The 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 کاملAnalysis of the Type Ia Supernova Sn1994d
On Mar. 7, 1994, Treffers, Filippenko and Van Dyk (1994) discovered the Type Ia supernova (SN Ia) 1994D in the SO galaxy NGC 4526, a member of the Virgo cluster which was was about 12 days before maximum light. Subsequently, both the light curve in Johnson’s UBVRI colors and spectra a have been monitored by several groups (e.g. Filippenko et al. private communication, Smith et al., 1995) making...
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...
متن کاملThe Type Ia Supernova Width-luminosity Relation
Observations of type Ia supernovæ at high redshifts have become an important tool for studying the geometry of the universe. The relation between the duration of the peak phase of a type Ia supernova’s lightcurve and its luminosity (broader is brighter) forms the cornerstone of this measurement, yet it is a purely empirical relation. In this paper we show that the relation is a natural conseque...
