Adiabatic Oscillations of Stars [PDF]

open access: bronzePublications of the Astronomical Society of Australia, 1970
In the past a number of analytical solutions have been found to the differential equation for small radial adiabatic oscillations of stars, with the aid of a series expansion of the form leading to a two-term recurrence relation.

Rapid Oscillations of CP2-Stars [PDF]

open access: bronzeInternational Astronomical Union Colloquium, 1986
With the announcement in 1978 (Kurtz, 1978) of short periodic photometric variations of HD 101065, the first member of a subgroup of CP2 stars was found. This gained attention due to the possibility of applying the methods of stellar seismology to late A to early F type stars.

Radial oscillations of relativistic stars [PDF]

open access: bronzeAstronomy & Astrophysics, 2001
We present a new survey of the radial oscillation modes of neutron stars. This study complements and corrects earlier studies of radial oscillations. We present an extensive list of frequencies for the most common equations of state and some more recent ones.

Oscillations of rapidly rotating stars [PDF]

open access: greenInternational Astronomical Union Colloquium, 2001
AbstractWe present numerical simulations of gravito-inertial waves propagating in radiative zones of rapidly rotating stars. A first model, using the Boussinesq approximation, allows us to study the oscillations of a quasi-incompressible stratified fluid embedded in a rapidly rotating sphere or spherical shell. In a second step, we investigate the case

On the oscillation spectra of ultra compact stars [PDF]

open access: greenProceedings of the Royal Society of London. Series A: Mathematical and Physical Sciences, 1995
Quasi-normal modes of ultra compact stars with uniform energy density have been calculated. For less compact stars, there is only one very slowly damped polar mode (corresponding to the Kelvin f-mode) for each spherical harmonic index l .

Nonradial oscillations of quark stars [PDF]

open access: greenPhysical Review D, 2003
Recently, it has been reported that a candidate for a quark star may have been observed. In this article, we pay attention to quark stars with radiation radii in the reported range. We calculate nonradial oscillations of $f$-, $w$- and $w_{\rm II}$-modes.

Oscillations on the star Procyon [PDF]

open access: yesNature, 2004
Stars are sphere of hot gas whose interiors transmit acoustic waves very efficiently. Geologists learn about the interior structure of Earth by monitoring how seismic waves propagate through it and, in a similar way, the interior of a star can be probed using the periodic motions on the surface that arise from such waves. Matthews et al. claim that the

Boson stars and their radial oscillations [PDF]

open access: yesPhysical Review D, 2021
We review the derivation of the pulsations equations for spherically symmetric boson stars and then make a thorough study of the radial oscillation frequencies for the fundamental and first excited modes. We do this for self-interacting boson stars and consider a range of values for the self-coupling constant. We also numerically evolve boson stars and
