Unstable spiral modes in disk-shaped galaxies: A general fluid dynamical theory with some preliminary results
A numerical scheme has been devised to calculate discrete spiral modes in a fluid-dynamical model of disk galaxies. The procedure is free from the usual restrictions imposed upon the asymptotic theory. A radiation condition has been formulated as one of the boundary conditions. For a test model gala...
