The Solution of Two-Dimensional Problems in Astrophysics.
Abstract
Techniques for studying the general hydrodynamic behavior of problems in two dimensional cylindrical coordinates with rotational symmetry are discussed. The hydrodynamic behavior of off-center point explosions in stars is considered. An important application of these calculations is the possible formation of high velocity pulsars. Unless a supernova mechanism can be found which is able to produce enough energy in a small region of the star, off-center explosions do not provide a satisfactory explanation for high velocity pulsars. Research to determine whether the impact of an expanding supernova shell on a binary companion star can disrupt the binary system is presented. It is unlikely that the collision between the supernova shell and the companion star will have a significant effect on the orbit of the binary system except perhaps in a few extreme cases.
