The wavefront propagation of curved detonation waves in carbon–oxygen cores and helium shells of Type Ia supernova (SNIa) progenitors is determined via a detonation shock dynamics approach. A level set implementation is used to track the front, which is evolved according to intrinsic quasi-steady, quasi-one-dimensional detonation speed–curvature relationships. The effects of curvature are analysed...
