The GRB-Supernova Connection
Long-duration gamma-ray bursts (GRBs) are believed to be produced by the core collapse of massive stars and hence to be connected with supernovae (SNe). Indeed, for four pairs of GRBs and SNe, spectroscopically confirmed connection has been firmly established. For more than a dozen of GRBs the SN signature (the ‘red bump’) has been detected in the afterglow lightcurves. Based on the four pairs ...
متن کاملThe supernova connection.
he fog surrounding the identity of the progenitors of ȍ-ray bursts (GRBs) is beginning to lift, at least for the class of GRBs known as 'long' bursts. This is thanks to a series of observations of a burst that began on 29 March 2003, very close to our Galaxy. On pages 843, 844 and 847 of this issue, Uemura et al. 1 , Price et al. 2 and Hjorth et al. 3 reveal the evolution of this burst in unpre...
متن کاملThe Supernova-Gamma Ray Burst Connection
Supernovae 1998bw and its corresponding relativistically expanding radio source are coincident with the γ-ray burst source GRB 980425. We show that of six recent SN Ib/c for which an outburst epoch can be estimated with some reliability, four have radio outbursts and all are correlated in time and space with BATSE γ-ray bursts. The joint probability of all six correlations is 1.5×10. No such co...
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...
