  The feasibility of the Double Detonation mechanism, -a surface
Helium-detonation followed by the complete carbon detonation of the core-, in a
rotating white dwarf with a mass $\simeq 1 M_{\odot}$ is studied using
three-dimensional hydrodynamic simulations. Assuming rigid rotation, the
rotational speed is taken high enough as to considerably distort the initial
spherical geometry of the white dwarf. Unlike spherically symmetric models, we
found that when helium ignition is located far from the spinning axis the
detonation fronts converge asynchronically at the antipodes of the igniting
point. Nevertheless, the detonation of the carbon core still remains as the
most probable outcome. The detonation of the core gives rise to a strong
explosion, matching many of the basic observational constraints of Type Ia
Supernova. We conclude that the Double Detonation mechanism also works when the
white dwarf is spinning fast. This confirms the sub-Chandrasekhar-mass models
and, maybe some Double Degenerate models (those having some helium fuel at the
merging moment), as appealing channels to produce Type Ia Supernova events.
