The evolution of supernova remnants. III. Thermal waves.
Abstract
The effect of heat conduction on the evolution of supernova remnants is investigated. A thermal wave, or electron conduction front, can travel more rapidly than a shock wave during the first thousand years of the remnant's evolution. A self-similar solution describing this phase has been found by Barenblatt. Numerical computations verify the solution and give the evolution past the thermal-wave phase. While shell formation is not impeded, the interior density and temperature profiles are smoothed by the action of conduction.
