نویسنده
چکیده
The launch of the Beppo-Sax satellite gave a unique opportunity to investigate gamma ray bursts (GRB) in different spectral regions. The large diversity of the afterglow behavior creates additional problems for the cosmological model with a fireball. Formation of the afterglow giving the observed diversity of properties is suggested in the Galactic neutron star model of GRBs. It is based on the transient accretion disc formation around the neutron star with a low-mass brown companion irradiated by the neutron star.

The present common view about GRB origin is related to cosmology. There are two evidences in favour of this interpretation. The first is connected with statistics, the second is based on measurements of the redshifts in the GRB optical afterglows. Red shifts in optical afterglows had been observed only in long GRB. Statistical errors, and possibility of galactic origin of short GRB is discussed...

The fourth unambiguously identified Soft Gamma Repeater (SGR), SGR 1627–41, was discovered with the BATSE instrument on 15 June 1998. Interplanetary Network measurements and BATSE data constrained the location of this new SGR to a 6 segment of a narrow (19) annulus (Hurley et al. 1999c; Woods et al. 1998). The All-Sky Monitor (ASM) on RXTE observed two bursts from this source. We use the ASM da...

We report evidence from the 3B Catalogue that short (T90 < 10 s) and long (T90 > 10 s) GRB represent different populations and processes: Their spectral behavior is qualitatively different, with short bursts harder in the BATSE range, but chiefly long bursts detected at higher photon energies; 〈V/Vmax〉 = 0.385 ± 0.019 for short GRB but 〈V/Vmax〉 = 0.282 ± 0.014 for long GRB, differing by 0.103 ±...
