We study a new type of self-gravitating object, described by a soliton solution to the coupled system of the Einstein equation and a matter field equation. The solution describing the self-gravitating object is not static but, instead, is periodic, with both the spacetime geometry and the matter field oscillating in time.

We study the relativistic quadrupole oscillations (ι= 2) of strange quark stars by calculating their quasi-normal modes, and we thus explore the possibility of using these oscillation frequencies and damping times to differentiate among relativistic polytropic stars, neutron stars, pure light-quark stars, and hybrid neutron stars with quark cores.

A brief introduction to the rapidly oscillating Ap (roAp) stars and a review of their properties is presented. Evidence which strongly suggests that the roAp stars pulsate obliquely in high-overtone, low-degree modes is shown. This review then concentrates on four problems of particular interest to asteroseismologists: 1) The interpretation of the ...

Anharmonic Oscillations of Massive Stars [PDF]
The 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

On the non-radial oscillations of a star
Proceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1991A complete theory of the non-radial oscillations of a static spherically symmetric distribution of matter, described in terms of an energy density and an isotropic pressure, is developed, ab initio , on the premise that the oscillations are excited by incident gravitational waves.

Non-radial oscillations of a star
Astrophysics and Space Science, 1990The non-radial oscillations of the homogeneous model of a star have been investigated taking into account the variation of the ratio of the specific heats. The stability of the oscillations thus set in is established.
