Nonradial Pulsation of General-Relativistic Stellar Models. III. Analytic and Numerical Results for Neutron Stars

Numerical techniques are developed for calculating the properties of the nonradial, quasi-normal pulsations of fully relativistic stellar models. These techniques are then applied to calculate, for four realistic neutron-star models, the following characteristics of the lowest few quadrupole p-type modes: the pulsation periods (-~-4O~ sec), the gravitational-radiation damping times (`-`1 sec), the pulsation energies (r~_4O52 ergs), the power emitted in gravitational waves (~~~4O52 ergs sec'), and the shapes of the fluid motions. Analytic techniques are used to show that many, and perhaps all, of the g-type modes of a neutron star have zero frequency, if thermal pressures are negligible compared with nuclear pressures
