Physics of Thermonuclear Explosions: Magnetic Field Effects on Deflagration Fronts and Observable Consequences

We present a study of the influence magnetic field strength and morphology in Type Ia Supernovae their late-time light curves spectra. In order to both capture self-consistent topologies as well evolve our models late times, two stage approach is taken. early deflagration phase (1s) using variety strengths, find that topology set by burning, independent initial strength. time (~1000 days) spectra with topologies, infer strengths from observed supernovae. Lower limits are found be 106G. This determined escape, or lack thereof, positrons tied field. The first employs 3d MHD local burning approximation, uses code Enzo. second hybrid approach, 3D radiation positron transport, spherical hydrodynamics. HYDRA. models, amplification remains small during phase. Late-time bear imprint morphology. Implications for alternative explosion scenarios discussed.
