Alfvén QPOs in Magnetars
Hajime Sotani, Kostas Kokkotas, Nikolaos Stergioulas
We investigate torsional Alfvén oscillations of relativistic stars with a global dipole magnetic field, via two-dimensional numerical simulations. We find that a) there exist two f…
Torsional Oscillations of Relativistic Stars with Dipole Magnetic Fields II. Global Alfvén Modes
H. Sotani, K. D. Kokkotas, N. Stergioulas +1
We investigate torsional Alfvén modes of relativistic stars with a global dipole magnetic field. It has been noted recently (Glampedakis et al. 2006) that such oscillation modes co…
Non-axisymmetric instability and fragmentation of general relativistic quasi-toroidal stars
Burkhard Zink, Nikolaos Stergioulas, Ian Hawke +3
In a recent publication, we have demonstrated that differentially rotating stars admit new channels of black hole formation via fragmentation instabilities. Since a higher order in…
