The triple ring nebula around SN 1987A

Abstract:

We present 3-dimensional hydrodynamical calculations to illustrate the formation of the triple ring nebula around SN 1987A. The outer rings most likely originated similar to 20 000 years before the supernova (SN) as the result of the merger of a 15 + 5 M circle dot binary after the primary had completed helium core burning. We show that the rapid merging in a rotating envelope leads to enhanced mass ejection at intermediate latitudes, while mass ejection close to the equatorial plane only occ...
