Abstract

We present results of exploratory, two-dimensional numerical calculations of a local thermonuclear runaway on the surface of a white dwarf. We find that the energy released by the runaway can induce a significant amount of vorticity near the burning region. Such mass motions account naturally for mixing of core matter into the envelope during the explosion. A new mechanism for the lateral spread of nuclear burning is also discussed.
