A Nitrogen-rich Supernova Remnant in M31: Interaction with the Circumstellar Medium at Late Times
We present the discovery of a supernova remnant in M31 which is unlike any other remnant known in that galaxy. An optical ground-based spectrum of WB92-26 taken at the MMT and sampling most of this marginally resolved object reveals strong lines of [O ii ], [Ne iii ], H i , [O iii ], [O i ], [N ii ]...
