Photometry and spectrometry of supernova 1987A : 558-786 days after the eruption.
Abstract
Photometry and spectrometry information has been collected on supernova 1987A from September 1988 through April 1989. The data show the beginning of the next stage in the development of the supernova remnant. This stage apparently began on the 640th day after the explosion and is characterized by an exponential brightness decline with tau = 73 exp d.
