Description
The recent supernova in the Large Magellanic Cloud (LMC), SN1987A, is positionally coincident with the B3 I supergiant star, Sk-69 202. Ultraviolet observations of this region made with the International Ultraviolet Explorer satellite after the explosion now show this star to have disappeared. Initial doubts that a blue supergiant could be a supernova progenitor may be overcome by calculations of the evolution of massive stars at reduced metallicity, as expected in the Magellanic Clouds. The authors present an alternative model for SN1987A in which the progenitor was a close binary companion of Sk-69 202. (author)
