Incompressible fluid binary systems with internal flows – models of close binary neutron star systems with spin

In this paper we have examined numerically exact configurations of close binary systems composed of incompressible fluids with internal flows. Component stars of binary systems are assumed to be circularly orbiting each other but rotating nonsynchronously with the orbital motion, i.e. stars in binary systems have steady motions seen from a rotational frame of reference. We have computed several...

Gas flow in close binary star systems

An accretion disc around a compact star in a close binary star system is an ubiquitous and essential object. Accretion discs play, for example, important roles in cataclysmic variables, nova and X-ray sources. The standard theory to explain the physics in accretion discs is the α-disc model proposed by Shakura and Sunyaev (1973). In this theory, the accretion disc is in some kind of turbulent s...

Relativistic hydrodynamics in close binary systems: Analysis of neutron-star collapse

We discuss the underlying relativistic physics that causes neutron stars to compress and collapse in close binary systems as has been recently observed in numerical (311)-dimensional general relativistic hydrodynamic simulations. We show that compression is driven by velocity-dependent relativistic hydrodynamic terms which increase the self-gravity of the stars. They also produce fluid motion w...

The Masses of Two Binary Neutron Star Systems

The measurement or constraint of the masses of neutron stars and their binary companions tests theories of neutron star structure and of pulsar formation and evolution. We have measured the rate of the general relativistic advance of the longitude of periastron for the pulsar PSR B1802−07: ω̇ = 0. 060 ± 0. 009 yr, which implies a total system mass, pulsar plus companion star, of M = 1.7 ± 0.4M⊙....

Binary Neutron Star Mergers

We review the current status of studies of the coalescence of binary neutron star systems. We begin with a discussion of the formation channels of merging binaries and we discuss the most recent theoretical predictions for merger rates. Next, we turn to the quasi-equilibrium formalisms that are used to study binaries prior to the merger phase and to generate initial data for fully dynamical sim...
