Supernova 1987A In Lmc, Supernovae: Circumstellar Shells

Scientific paper

The Space Telescope Science Institute coronograph (described in the Messenger, 47, p.43) mounted on the 2.2-m telescope at La Silla was used by myself and my colleague Chris Burrows to look for light echos in the immediate vicinity of the SN 1987A in the LMC. This technique allows us to probe circumstellar regions from about 2 to 20 arcseconds in the vicinity of very bright objects such as the SN 1987A for faint features otherwise completely lost in their glare.
