Relativistic precession around rotating neutron stars: Effects due to frame-dragging and stellar oblateness
Sharon M. Morsink, Luigi Stella
General relativity predicts that a rotating body produces a frame-dragging (or Lense-Thirring) effect: the orbital plane of a test particle in a non-equatorial orbit precesses abou…
Quasi-normal modes of rotating relativistic stars - neutral modes for realistic equations of state
Sharon M. Morsink, Nikolaos Stergioulas, Steve R. Blattnig
We compute zero-frequency (neutral) quasi-normal f-modes of fully relativistic and rapidly rotating neutron stars, using several realistic equations of state (EOSs) for neutron sta…
The late-time singularity inside non-spherical black holes
Patrick R Brady, Serge Droz, Sharon M Morsink
It was long believed that the singularity inside a realistic, rotating black hole must be spacelike. However, studies of the internal geometry of black holes indicate a more compli…
Gravitational Radiation Instability in Hot Young Neutron Stars
Lee Lindblom, Benjamin J. Owen, Sharon M. Morsink
We show that gravitational radiation drives an instability in hot young rapidly rotating neutron stars. This instability occurs primarily in the l=2 r-mode and will carry away most…
