Anharmonic Oscillations of Massive Stars
Publications of the Astronomical Society of Australia, 1968The equation of motion, derived from the basic Lagrangian equations for the conservation of momentum and the conservation of energy, for non-linear non-adiabatic radial oscillations of a pulsating star takes the form

Rapid Oscillations of Ap Stars
Publications of the Astronomical Society of Japan, 1985Abstract We interpret the rapid oscillations of Ap stars as a superposition of high overtone p-modes with the radial order n ≃ 30–40 and low degree l (l = 0–3). We have calculated the value of ν0≡2∫0Rc-1dr-1, which gives a good measure of the frequency separation of the consecutive overtones with a fixed value of l, for stellar ...

Magnetohydrodynamic Oscillations of Neutron Stars
Nature Physical Science, 1971FLUID motions in neutron stars have been investigated theoretically several times1–3, but the problem of free magnetohydrodynamic oscillations has evidently not been considered previously, notwithstanding its possible importance in connexion with the interpretation of pulsar observations4–7, especially the modulation of pulse rates8,9.

Rotating and Oscillating Neutron Stars
1996Since neutron stars are extremely compact objects with strong gravity, general relativity must be employed in modelling their properties. The structure and gravitational fields of spherically symmetric, nonrotating stars are governed by the Tolman-Oppenheimer-Volkoff equations, a set of ordinary differential equations.

Bifurcations in Non Oscillating Stars
1990The equations of a polytropic gas sphere are studied from the point of view of similarity solutions and Quasi-Invariance transformations. Ordinary differential equations are obtained that generalize Emden’s equations. Critical points are seen to exist in most cases and lead to bifurcations in the density space.
