چکیده

We discuss the possible connection between supernova explosions (SN) and gamma-ray bursters (GRB) from the perspective of our current understanding of SN physics. Recent evidence strongly suggests that the explosion mechanism of core collapse SN is intrinsically aspherical. Typically, a neutron star is formed. However, the observed properties of the expanding SN envelopes remnants make these objects very unlikely candidates for GRBs. Most candidates for a GRB/SN connection seem to require the prompt or delayed formation of a black hole. These include the collapse of very massive stars (e.g. hypernovae) and ’classical’ SNe with a significant fallback of material over time scales of hours to days, resulting in the collapse of the neutron star to a black hole. We suggest the merger of a neutron star with a white dwarf as a subclass of thermonuclear SNe and a potential candidate for a SN/GRB connection.

The attempt to secure conclusive, spectroscopic evidence for the GRB/SN connection has been a central theme in most GRB observing time proposals since the discovery of the very unusual GRB 980425 associated with the peculiar type Ib/c SN 1998bw. GRB 030329 provided this evidence to everybody’s satisfaction. In this contribution we show the results of a spectroscopic campaign of the supernova as...

We discuss two main aspects of the GRB 000301C afterglow [1,2]; its short duration and its possible connection with a Damped Lyα Absorber (DLA). GRB 000301C falls in the short class of bursts, though it is consistent with belonging to the proposed intermediate class or the extreme short end of the distribution of long-duration GRBs. Based on two VLT spectra we estimate the H I column density to...

The spectrometer SPI on board INTEGRAL is capable of high-resolution spectroscopic studies in the energy range 20 keV to 8 MeV for GRBs which occur within the fully coded field of view (16 • corner to corner). Six GRBs occurred within the SPI field of view between October 2002 and November 2003. We present results of the analysis of the first two GRBs detected by SPI after the payload performan...
