Did Supernova 1989B exhibit a light echo ?

MILNE P.A. and WELLS L.A.

Abstract (from CDS):

The late light curves of SN 1989B exhibited an emission excess relative to other Type Ia supernovae. We investigate whether this emission excess suggests light echo emission from this supernova or, rather, intense background galaxy contamination at the location of the supernova. We conclude that stellar emission can better explain the late spectra and that the emission excess is likely due to background contamination.
