Nuclear composition of gamma-ray burst fireballs
We study three processes that shape the nuclear composition of the fireballs in gamma-ray bursts (GRBs): (1) neutronization in the central engine, (2) nucleosynthesis in the fireball as it expands and cools, and (3) spallation of nuclei in subsequent internal shocks. The fireballs are shown to have a neutron excess and a marginally successful nucleosynthesis. They are composed of free nucleons,...
متن کاملBlandford-Znajek process as a gamma ray burst central engine
We investigate the possibility that gamma-ray bursts are powered by a central engine consisting of a black hole with an external magnetic field supported by a surrounding disk or torus. The rotational energy of the black hole can be extracted electromagnetically as a Poynting flux, a mechanism proposed by Blandford and Znajek(1977). Recently observed magnetars indicate that some compact objects...
متن کامل0 A Central Engine for Cosmic Gamma - Ray Burst Sources
One of a family previously proposed " central engines " for cosmic gamma-ray burst sources (Klu´zniak & Ruderman 1998) is considered in some detail. A steadily accreting 10 6 Gauss magnetic white dwarf should ultimately collapse to a strongly differentially rotating, millisecond-rotation-period neutron star for a wide range of steady accretion rates and initial masses if the accreting white dwa...
متن کاملThe Supernova Gamma-Ray Burst Connection
The chief distinction between ordinary supernovae and long-soft gamma-ray bursts (GRBs) is the degree of differential rotation in the inner several solar masses when a massive star dies, and GRBs are rare mainly because of the difficulty achieving the necessary high rotation rate. Models that do provide the necessary angular momentum are discussed, with emphasis on a new single star model whose...
متن کاملThe supernova-gamma-ray burst-jet connection.
The observed association between supernovae and gamma-ray bursts represents a cornerstone in our understanding of the nature of gamma-ray bursts. The collapsar model provides a theoretical framework for this connection. A key element is the launch of a bipolar jet (seen as a gamma-ray burst). The resulting hot cocoon disrupts the star, whereas the (56)Ni produced gives rise to radioactive heati...
