Normal Modes of Rotating Magnetic Stars
We investigate the effect of a magnetic field on the global oscillation modes of a rotating fluid star in the magnetohydrodynamic approximation. We present general equations for the modification of any type of fluid mode due to a general magnetic field which is not aligned with the star’s spin axis. In the case of any internal dipole magnetic field we derive the equations for the frequency corr...
متن کاملNon-rotating and rotating radiative-convective equilibrium
Radiative-convective equilibrium (RCE), in which the radiative cooling in the atmosphere is balanced by the convective heating in a horizontally homogeneous environment, is a good starting point for studying tropical convection. It also provides an idealized framework to compare analogous simulations by global climate models (GCMs) which rely on convective parameterizations, and cloud-resolving...

متن کاملr-modes of slowly rotating non-isentropic relativistic stars
We investigate properties of r-modes characterized by regular eigenvalue problem in slowly rotating relativistic polytropes. Our numerical results suggest that discrete r-mode solutions for the regular eigenvalue problem exist only for restricted polytropic models. In particular the r-mode associated with l = m = 2, which is considered to be the most important for gravitational radiation driven...
متن کاملNon-Rotating BTZ Black Hole Area Spectrum from Quasi-normal Modes
In this paper, by using the quasi-normal frequencies for non-rotating BTZ black hole derived by Cardos and Lemos, also via Bohr-Sommerfeld quantization for an adiabatic invariant, I = ∫ dE ω(E) , which E is the energy of system and ω(E) is vibrational frequency, we leads to an equally spaced mass spectrum. The result for the area of event horizon is An = 2π √ nmh̄ Λ which is not equally spaced, ...
