Radial oscillations of protoneutron stars

open access: yesPhysical Review D
We investigate radial oscillations of proto-neutron stars, employing equations of state described by the Brueckner-Hartree-Fock theory or the relativistic mean field model, and assuming isentropy and fixed lepton fractions for the internal structure.

Magnetic Oscillations in Radiative Stars [PDF]

open access: yesInternational Astronomical Union Colloquium, 2000
AbstractWhat drives acoustic modes in magnetic, radiative stars, such as the rapidly oscillating Ap (roAp) stars? We propose that oscillations in the shape of the magnetic field can drive magnetosonic waves, which are observed as p modes. The force-free atmosphere minimizes magnetic energy.

Nonradial oscillations of neutron stars

open access: yesThe Astrophysical Journal, 1988
Linear, adiabatic, Newtonian, nonradial pulsation analyses have been performed for finite-temperature neutron star models with a fluid core, solid crust, and thin surface fluid 'ocean', including the effects of the neutron star crust. The pulsation equations are considered, including the spheroidal and toroidal modes.
