Irrotational binary neutron stars in quasiequilibrium
We report on numerical results from an independent formalism to describe the quasiequilibrium structure of nonsynchronous binary neutron stars in general relativity. This is an important independent test of controversial numerical hydrodynamic simulations which suggested that nonsynchronous neutron stars in a close binary can experience compression prior to the last stable circular orbit. We sh...
متن کاملIrrotational Binary Neutron Stars in Quasiequilibrium in General Relativity
Neutron stars in binary orbit emit gravitational waves and spiral slowly together. During this inspiral, they are expected to have very little vorticity. It is in fact a good approximation to treat the system as having zero vorticity, i.e., as irrotational. Because the orbital period is much shorter than the radiation reaction time scale, it is also an excellent approximation to treat the syste...
متن کاملBinary Neutron Stars Systems: Irrotational Quasi-Equilibrium Sequences
We report on numerical results from an independent formalism to describe the quasi-equilibrium structure of nonsynchronous binary neutron stars in general relativity. This is an important independent test of controversial numerical hydrodynamic simulations which suggested that nonsynchronous neutron stars in a close binary can experience compression and even collapse prior to the last stable ci...
متن کاملBinary neutron star inspiral, LIGO, and cosmology
The most promising anticipated source for the United States Laser Interferometer Gravitational-wave Observatory (LIGO) or its French/Italian counterpart VIRGO is the radiation emitted during the final moments of inspiral before the coalescence of a neutron star neutron star (ns-ns) binary system. The instruments that will operate in the LIGO facility will evolve over time, and the often-discuss...
متن کاملAnalytic modeling of tidal effects in the relativistic inspiral of binary neutron stars.
To detect the gravitational-wave (GW) signal from binary neutron stars and extract information about the equation of state of matter at nuclear density, it is necessary to match the signal with a bank of accurate templates. We present the two longest (to date) general-relativistic simulations of equal-mass binary neutron stars with different compactnesses, C=0.12 and C=0.14, and compare them wi...
