D ec 1 99 7 Simulations of binary coalescence of a neutron star and a black hole
نویسندگان
چکیده
We present the results of Newtonian hydrodynamic simulations of the coalescence of a binary consisting of a black hole with a neutron star. The calculations show that for a wide range of initial conditions the core of the neutron star survives the initial mass transfer episode. We therefore identify black hole–neutron star binaries as the astrophysical production site of low mass neutron stars unstable to explosion. The relevance of the simulations to the theory of gamma–ray bursts is also discussed.

Black hole neutron star coalescence as a source of gamma–ray bursts
We present the results of hydrodynamic (SPH) simulations showing the coalescence of a black hole with a neutron star to be a promising theoretical source of short duration gamma-ray bursts. The favorable features of the process include rapid onset, millisecond variability, a duration much longer than the dynamical timescale, and a range of outcomes sufficient to allow variety in the properties ...

We used a newtonian SPH (smooth-particle hydrodynamics) code to follow the final stages of evolution of a coalescing binary system of a neutron star and a black hole. We find that the outcome of the “merger” is very sensitive to the equation of state describing the neutron star. A neutron star with a soft equation of state (polytrope with index Γ = 5/3) is completely disrupted, and a fairly lar...

We present a numerical study of the hydrodynamics in the final stages of inspiral in a black hole–neutron star binary, when the separation becomes comparable to the stellar radius. We use a Newtonian three–dimensional Smooth Particle Hydrodynamics (SPH) code, and model the neutron star with a soft (Γ = 5/3) polytropic equation of state and the black hole as a Newtonian point mass which accretes...
متن کاملCalculating Gravitational Radiation from Collisions
The development of both groundand space-based gravitational wave detectors provides new opportunities to observe the radiation from binaries containing neutron stars and black holes. Numerical simulations in 3-D are essential for calculating the coalescence waveforms, and comprise some of the most challenging problems in astrophysics today. This article briefly reviews the current status of eff...
متن کاملSimulations of black hole–neutron star binary coalescence
We show the results of dynamical simulations of the coalescence of black hole– neutron star binaries. We use a Newtonian Smooth Particle Hydrodynamics code, and include the effects of gravitational radiation back reaction with the quadrupole approximation for point masses, and compute the gravitational radiation waveforms. We assume a polytropic equation of state determines the structure of the...
