...Show More Authors

Optical spectrum of SN1987A at days 4 from the explosion and its light curve through the first 1444 days after the explosion have been studied. The hydrogen lines present in the spectrum confirms the general characteristics of Type II SN that occur due to core collapse of massive star. Each of the total mass ejected from the explosion and the amount of the total mass of Nickel radioactive isotopes that produced during the explosion as well as the initial velocity of the ejecta and the explosion energy have been determined and compared with different observed and calculated models obtained by different researchers and it’s found that, about 8.8 Mʘ of the progenitor envelope mass had been ejected during the explosion and it’s mixed with 0.077 Mʘ of Nickel radioactive isotopes are ejected with initial velocity equaled 3900 km.s-1 and with explosion energy equaled 1.34 x 1051erg. Moreover it’s found that, these results are in a good agreement with observational data.
