Quasiequilibrium sequences of synchronized and irrotational binary neutron stars in general relativity. I. Method and tests
E. Gourgoulhon, P. Grandclement, K. Taniguchi +2
We present a numerical method to compute quasiequilibrium configurations of close binary neutron stars in the pre-coalescing stage. A hydrodynamical treatment is performed under th…
Darwin-Riemann problems in general relativity
S. Bonazzola, E. Gourgoulhon, P. Grandclement +1
A review is given of recent results about the computation of irrotational Darwin-Riemann configurations in general relativity. Such configurations are expected to represent fairly…
Evolutionary sequences of irrotational binary neutron stars
S. Bonazzola, E. Gourgoulhon, J. -A. Marck
We present results of numerical computations of quasiequilibrium sequences of binary neutron stars with zero vorticity, in the general relativistic framework. The Einstein equation…
Spectral methods in general relativistic astrophysics
S. Bonazzola, E. Gourgoulhon, J. -A. Marck
We present spectral methods developed in our group to solve three-dimensional partial differential equations. The emphasis is put on equations arising from astrophysical problems i…
Numerical approach for high precision 3-D relativistic star models
S. Bonazzola, E. Gourgoulhon, J. -A. Marck
A multi-domain spectral method for computing very high precision 3-D stellar models is presented. The boundary of each domain is chosen in order to coincide with a physical discont…
Spectral methods in general relativity -- toward the simulation of 3D-gravitational collapse of neutron stars
S. Bonazzola, J. Frieben, E. Gourgoulhon +1
Several applications of spectral methods to problems related to the relativistic astrophysics of compact objects are presented. Based on a proper definition of the analytical prope…
