Description

Spatially resolved IUE spectra (1150 - 2000 A) taken at the position of SN 1987A in March 1987 show that the 12th mag B3 I star Sk -690 202 has disappeared. Only the two fainter companion stars (Star 2 and Star 3) are now present near the site of the supernova. Sk -690 202 is the star which exploded to produce SN 1987A. The known characteristics of Sk -690 202 are consistent with the interpretation that the progenitor was a relatively compact star, having a high-velocity low-density stellar wind prior to the outburst. Recent IUE spectra of SN 1987 A (May 1988) show no evidence that Sk -690 202 still exists inside the expanding ejecta
