Radial and nonradial oscillations of partially-degenerate stellar masses

The radial and nonradial modes of oscillation of partially degenerate stellar masses have been studied. It is found that the radial mode shows a decrease with increased central condensation and the configuration tends, therefore, towards a marginally stable point with increased degeneracy. The nonradial modes forl=2 and 3 also shows a similar trend. However, the decrease is slower than the corresponding radial mode.
