Physical constraints on models of gamma-ray bursters [PDF]
AbstractThe power per logarithmic bandwidth in gamma-ray burst spectra generally increases rapidly with energy through the x-ray range and does not cut off sharply above a few MeV. This spectral form indicates that a very small fraction of the energy from a gamma-ray burst source is emitted at low energies or is reprocessed into x-rays and that the ...

Theory of Gamma Ray Bursters [PDF]
Gamma ray bursters are interpreted as nuclear explosions under the surface of neutron stars. The explosions occur after transportation of the matter with nonequilibrium composition during starquakes in outer layers where the matter becomes unstable and explodes as a result of a developing chain reaction.

Origin of Gamma Ray Bursters [PDF]
The successful discovery of X-ray, optical and radio afterglows of GRB has made possible the identification of host galaxies at cosmological distances. The energy release inferred in these outbursts place them among the most energetic and violent events in the Universe.

Gamma-ray burster counterparts - Archival data
This paper reports on the results of a search for optical transient images associated with gamma-ray bursters based on the collection of archival photographs at the Harvard College Observatory. This study searched through over 32,000 plates showing 16 gamma-ray burst error regions.

The Magellanic Clouds as the source of gamma-ray bursters [PDF]
We present a new model for gamma-ray bursts to explain their isotropic but inhomogeneous space distribution. We propose that the Magellanic Clouds are the source of a special population of gamma-ray-bursting pulsars which are easily ejected from the Clouds and lead to a halo distribution which is homogeneous within a radius of ∼ 50 kpc and falls off ...

Gamma ray bursters and black holes in gravity’s rainbow
In this paper, we analyze the modification to the thermodynamics of a Schwarzschild black hole and a Kerr black hole due to gravity’s rainbow. The metric for these black holes will be made energy dependent. This will be done by using rainbow functions motivated from the hard spectra from gamma-ray bursters at cosmological distances.

Simulations of X-ray bursts and superbursts [PDF]
Observations of neutron star in binary systems provide powerful constrains on the physics at the surface of neutron stars. During the accretion of matter from the companion star, periodic nuclear explosion are triggered in the outer layers of the neutron

THE NUMERICAL THREE-DIMENSIONAL HYDRODYNAMIC SIMULATION OF THE γ-RAY BURSTERS AND X-RAY BURSTERS
An radiative wind accretion on to the compact object in a detached close binary system (CBS) where one of the components is a supergiant with radiation stellar wind that blows from its surface, and another component is a compact object (black hole or ...
