Analytical Expressions For Light-curves of Supernovae Type Ia    [PDF]

Shlomo Dado, Arnon Dar
A simple analytical model is used to derive the main properties of supernovae type Ia (SNe Ia), which are produced by the thermonuclear explosion of accreting C-O white dwarfs that cross the Chandrasekhar mass limit. The few underlying physical assumptions of the model yield analytical expressions that reproduce quite well the observed bolometric light-curves of SNe Ia and the empirical brighter-slower and brighter-bluer relationships that were used to standardize SNe Ia for their use as distance indicators, which led to the discovery of the accelerating expansion of the universe.
