Abstract

The λ-ray burst of 1997 February 28 is analyzed within the Electromagnetic Black Hole model. We first estimate the value of the total energy deposited in the dyadosphere, Mdyaa nd the amount of baryonic matter left over by the EMBH progenitor star, B = MBC 2/Edya- We then consider the role of the interstellar medium number density njsMand of the ratio R between the effective emitting area and the total surface area of the 7-ray burst source, in reproducing the prompt emission and the X-ray afterglow of this burst. Some considerations are also done concerning the possibility of explaining, within the theory, the observed evidence for a supernova in the optical afterglow.
