Dynamics of oscillating relativistic tori around Kerr black holes
O. Zanotti, J. A. Font, L. Rezzolla +1
We present a comprehensive numerical study of the dynamics of relativistic axisymmetric accretion tori with a power-law distribution of specific angular momentum orbiting in the ba…
Oscillations of vertically integrated relativistic tori -II. Axisymmetric modes in a Kerr spacetime
Pedro J. Montero, Luciano Rezzolla, Shin'ichirou Yoshida
This is the second of a series of papers investigating the oscillation properties of relativistic, non-selfgravitating tori orbiting around black holes. Extending the work done in…
Electromagnetic Fields in the Exterior of an Oscillating Relativistic Star -- I. General Expressions and application to a rotating magnetic dipole
Luciano Rezzolla, Bobomurat J. Ahmedov
Relativistic stars are endowed with intense electromagnetic fields but are also subject to oscillations of various types. We here investigate the impact that oscillations have on t…
Three-dimensional relativistic simulations of rotating neutron-star collapse to a Kerr black hole
L. Baiotti, I. Hawke, P. J. Montero +5
We present a new three-dimensional fully general-relativistic hydrodynamics code using high-resolution shock-capturing techniques and a conformal traceless formulation of the Einst…
A New, Simple Model for Black Hole High Frequency QPOs
L. Rezzolla
Observations of X-ray emissions from binary systems have always been considered important tools to test the validity of General Relativity in strong-field regimes. The pairs and tr…
