Binary black holes in circular orbits. I. A global spacetime approach
E. Gourgoulhon, P. Grandclement, S. Bonazzola
We present a new approach to the problem of binary black holes in the pre-coalescence stage, i.e. when the notion of orbit has still some meaning. Contrary to previous numerical tr…
Numerical models of irrotational binary neutron stars in general relativity
S. Bonazzola, E. Gourgoulhon, J. -A. Marck
We report on general relativistic calculations of quasiequilibrium configurations of binary neutron stars in circular orbits with zero vorticity. These configurations are expected…
Spontaneous symmetry breaking of rapidly rotating stars in general relativity: influence of the 3D-shift vector
S. Bonazzola, J. Frieben, E. Gourgoulhon
An analytical scheme and a numerical method in order to study the effects of general relativity on the viscosity driven secular bar mode instability of rapidly rotating stars are p…
A relativistic formalism to compute quasi-equilibrium configurations of non-synchronized neutron star binaries
S. Bonazzola, E. Gourgoulhon, J. -A. Marck
A general relativistic version of the Euler equation for perfect fluid hydrodynamics is applied to a system of two neutron stars orbiting each other. In the quasi-equilibrium phase…
Spontaneous Symmetry Breaking of Rapidly Rotating Stars in General Relativity
S. Bonazzola, J. Frieben, E. Gourgoulhon
We investigate the effects of general relativity upon the non-axisymmetric ``bar'' mode secular instability of rapidly rotating stars, i.e. the relativistic and compressible analog…
