Supernovae and Supernova Remnants: The Big Picture in Low ResolutionA supernova is a star ending its life in a powerful explosion, nearly always leaving behind an expanding gaseous remnant, which has an influence on the surrounding circumstellar and interstellar......
They are hydrodynamics-only models that focus on critical aspects of the shock stability and dynamics and their impact on the supernova mechanism and explosion. The two-dimensional simulations demonstrate the important role nuclear burning may play despite the relatively small total energy deposition ...
The expanding debris cloud known as Cassiopeia A is an example of this final phase of the stellar life cycle. Light from the supernova explosion that created this remnant would have been first seen in planet Earth's sky about 350 years ago, although it took that light 11,000 years to ...
Part of a binary star system, the compact white dwarf gradually captured material from its companion star. The buildup in mass finally triggered a thermonuclear explosion that destroyed the dwarf star. Because the distance to the supernova remnant is about 7,000 light-years, that explosion ...

A supernova is a star ending its life in a powerful explosion, nearly always leaving behind an expanding gaseous remnant, which has an influence on the surrounding circumstellar and interstellar medium, and possibly a compact stellar remnant. Multiple supernovae events, collectively, can have a ...
supernovae: individual: SN1993Jgalaxies: individual: M81We report on a simultaneous modelling of the expansion and radio light curves of SN1993J. We have developed a simulation code capable of generating synthetic expansion and radio light curves of supernovae by taking into consideration the ...
