A complex three-ring shaped structure has been reported extending some arcseconds around the SN 1987A central spot by several authors. This structure is believed to arise when a thin shell of matter surrounding the supernova was illuminated by the initial extreme-ultraviolet flash from the explosion of the progenitor.

Abstract

A complex three-ring shaped structure has been reported extending some arcseconds around the SN 1987A central spot by several authors. This structure is believed to arise when a thin shell of matter surrounding the supernova was illuminated by the initial extreme-ultraviolet flash from the explosion of the progenitor. In this view the two ring-shaped outer loops, ≡3″in size, are interpreted as limb brightening of an hourglass-shaped nebula surrounding the supernova, while the smaller central ring is located at the waist of the hourglass. The explanation of the two external loops is different: keeping the hourglass-shaped nebula scenario, the authors believe that these loops result from the interaction of this nebula with a double beam of relativistic particles emitted by a young pulsar formed by the supernova.
