X-Ray Observation of SN 1987A from GINGA
Abstract
An X-ray light curve of SN 1987A was obtained from Ginga over a 1000-day period since its outburst. X-rays from the SN appear to comprise two separate components: a hard and a soft component. Hard X-rays were first detected in July 1987, reached a maximum near the end of 1987, and declined steadily through January 1989. Later, the hard component has been close to or below the detection limit. A remarkable soft X-ray flare conclusively from SN 1987A occurred in January 1988. In addition, soft X-rays were occasionally observed significantly in the region of SN 1987A.
