Hyperon softening of the EOS of dense matter and the spin evolution of isolated neutron stars
J. L. Zdunik, P. Haensel, E. Gourgoulhon +1
The effect of the hyperon softening of the equation of state (EOS) of dense matter on the spin evolution of isolated neutron stars is studied for a broad set of hyperonic EOSs. We…
Are rotating strange quark stars good sources of gravitational waves?
D. Gondek-Rosinska, E. Gourgoulhon, P. Haensel
We study the viscosity driven (Jacobi-like) bar mode instability of rapidly rotating strange stars in general relativity. A triaxial, "bar shaped" compact star could be an efficien…
Various features of quasiequilibrium sequences of binary neutron stars in general relativity
Keisuke Taniguchi, Eric Gourgoulhon
Quasiequilibrium sequences of binary neutron stars are numerically calculated in the framework of the Isenberg-Wilson-Mathews (IWM) approximation of general relativity. The results…
Evolutionary sequences of rotating protoneutron stars
Loic Villain, Jose A. Pons, Pablo Cerda-Duran +1
We investigate the evolution of rigidly and differentially rotating protoneutron stars (PNSs) during the first twenty seconds of their life. We solve the equations describing stati…
A constrained scheme for Einstein equations based on Dirac gauge and spherical coordinates
S. Bonazzola, E. Gourgoulhon, P. Grandclement +1
We propose a new formulation for 3+1 numerical relativity, based on a constrained scheme and a generalization of Dirac gauge to spherical coordinates. This is made possible thanks…
