8 Thermonuclear Supernovae
The application of Type Ia supernovae (SNe Ia) as distance indicators in cosmology calls for a sound understanding of these objects. Recent years have seen a brisk development of astrophysical models which explain SNe Ia as thermonuclear explosions of white dwarf stars. While the evolution of the progenitor is still uncertain, the explosion mechanism certainly involves the propagation of a ther...
متن کاملTidally-induced thermonuclear Supernovae
We discuss the results of 3D simulations of tidal disruptions of white dwarfs by moderate-mass black holes as they may exist in the cores of globular clusters or dwarf galaxies. Our simulations follow self-consistently the hydrodynamic and nuclear evolution from the initial parabolic orbit over the disruption to the build-up of an accretion disk around the black hole. For strong enough encounte...
متن کاملSpectropolarimetric diagnostics of thermonuclear supernova explosions.
Even at extragalactic distances, the shape of supernova ejecta can be effectively diagnosed by spectropolarimetry. We present results for 17 type Ia supernovae that allow a statistical study of the correlation among the geometric structures and other observable parameters of type Ia supernovae. These observations suggest that type Ia supernova ejecta typically consist of a smooth, central, iron...
متن کاملSummary of the Thermonuclear Explosions Working Group
Over the past decade a large number of supernovae have been observed. We have detailed spectra and lightcurves of many events. These observations have shown that there is a lot of diversity in events, and looking at the properties of Ias with host galaxy have led to the argument that there may be distinct populations or multiple progenitor mechanisms at work. Finally, some observations suggest ...
متن کاملAntimatter Induced Fusion and Thermonuclear Explosions *
The feasibility of using antihydrogen for igniting inertial confinement fusion pellets or triggering large-scale thermonuclear explosions is investigated. The number of antiproton annihilations required to start a thermonuclear burn wave in either DT or Li2DT is found to be about 10/κ, where κ is the compression factor of the fuel to be ignited. In the second part, the technologies for producin...
