... we still lack a full understanding of the explosions which give rise to SNe Ia ... maximum luminosity, nickel masses, and explosion velocities for many nearby SNe Ia ... and nickel masses points to signi cant dif- ferences among the explosions ...
... The observations for the first 115 days after the SN explosion have been published previously by Pooley G.G. & Green D.A. (1993, MNRAS, 264, 17) , whereas the data presented here extend to about 500 days after the SN explosion. ...
... SN Ia, the UV-optical spectrum of SN 1990N obtained 14 days before B maximum, was modelled with a Monte Carlo code in order to determine its epoch and consequently the rise time from explosion to B max, which is important for tting template light curves ...
... The number of SNRs in the Galaxy at any one time and the rate of supernova explosions are quite important numbers to know, since supernova explosions are a primary mechanism for energizing the interstellar medium and re-cycling material into it. ...

... The optical light from the star brightens for a month or so; but at radio wavelengths we can observe the aftermath of the explosion for up to ten thousand years. ...

... GRBs are highly energetic explosions which are thought to be linked to the death of high-mass stars and therefore to trace star formation throughout the universe. ...
