Study Of Flashes On H/He Accreting CO White Dwarfs.

Type Ia Supernovae are important tools for high precision cosmological measurements. There are currently two suggested progenitor systems for Sne Ia, the double degenerate (DD) and single degenerate (SD) scenarios. An open question with the SD system is whether it is possible for the white dwarf to approach the Chandrasekhar mass, without the shell flashes causing the white dwarf to lose the mass it accreted. We will present full hydrodynamical 1-D model with the inclusion of rotational effects for various accretion rates and discuss our results.
