Rotation of the accreting white dwarfs and diversity of type Ia supernovae

We consider rotation of progenitor white dwarfs for a possible source of the diversity of Type Ia supernovae (SNe Ia). Hydrostatic structure of rotating white dwarfs with different masses are calculated. Evolutionary sequences of white dwarfs are explored and the effect of ``supercritical'' rotation in binary system is examined. Possible effects of rotation to cause diversity of SNe Ia are discussed.
