Gamma-ray bursts (GRB's), short and intense pulses of low-energy γ rays, have fascinated
astronomers and astrophysicists since their unexpected discovery in the late sixties. During …

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 …

Using a two-dimensional hydrodynamics code (PROMETHEUS), we explore the continued
evolution of rotating helium stars, M α≳ 10 M⊙, in which iron-core collapse does not …

ABSTRACT A variety of current models of gamma-ray bursts (GRBs) suggest a common
engine: a black hole of several solar masses accreting matter from a disk at a rate of 0.01 to …

ABSTRACT The optical afterglow of the gamma-ray burst GRB 9 Page 1 L45 THE …

We investigate the dynamics and evolution of coalescing neutron stars. The three-
dimensional Newtonian equations of hydrodynamics are integrated by the" Piecewise …

Three-dimensional hydrodynamical, Newtonian calculations of the coalescence of equal-
mass binary neutron stars are performed, including a physical high-density equation of state …

Three-dimensional simulations for the merger of binary neutron stars are performed in the
framework of full general relativity. We pay particular attention to the black hole formation …

We present numerical results of three-dimensional simulations for the merger of binary
neutron stars in full general relativity. Hybrid equations of state are adopted to mimic realistic …

Recent months have witnessed dramatic progress in our understanding of short γ-ray burst
(SGRB) sources. There is now general agreement that SGRBs—or at least a substantial …
