Supernovae are very luminous events, on the scale of entire galaxies, and deposit mass and large amounts of energy in to the surrounding interstellar medium. In this workthe effect of a supernova on the surrounding medium is studied. The evolution of the remnant is assumed to be spherical symmetric. The hydrodynamic evolution of the system is simulated for different density distributions of the ambient medium and compared to analytically solutions where they exists.Some background theory about stellar evolution and supernovae is given. Since strong shocks from supernovae is interesting in the context of cosmic ray acceleration some theory about cosmic is included.The framework for simulating the hydrodynamic equations governing the system is based on the work done by W.Benz.
