Abstract
A simple two-component fluid model of a galaxy is analyzed numerically. For this equilibrium configuration a large number of unstable spiral modes is found. It is of particular interest that some of these modes are well described by the asymptotic theory developed for tightly wound trailing spirals, while others are best understood in terms of the swing formalism which includes both leading and trailing waves.
