121“…In order to assist in planing the search of supernova (SN) in the late time afterglow (AG) of the gamma ray burst (GRB) 011121 we use the Cannonball Model of GRBs and the observations of its afterglow in the R band in the first two days to predict its late time decline and intrinsic spectrum.…”

129“…This result supports recent dust condensation calculations that predict a delayed formation of carbonaceous and SiC grains in supernovae. The astronomical observation of continuous buildup of dust in supernovae over several years can, therefore, be interpreted as a growing addition of C-rich dust to the dust reservoir in supernovae.…”

132por Campbell, J A“…Specific effects of the two-photon reaction on general models of the formation of supernovae are pointed out. In particular, the maximum mass of a star which can turn into a supernova may be quite low, and the fraction of mass ejected as cosmic rays may be increased significantly over the fraction in models without two-photon annihilation.…”
