Radial oscillations and stability of multiple-fluid compact stars

I derive a system of pulsation equations for compact stars made up of an arbitrary number of perfect fluids that can be used to study radial oscillations and stability with respect to small perturbations. I assume spherical symmetry and that the only interfluid interactions are gravitational. My der...
