Why did Supernova 1054 shine at late times?

SOLLERMAN J., KOZMA C. and LUNDQVIST P.

Abstract (from CDS):

The Crab nebula is the remnant of supernova 1054 (SN 1054). The progenitor of this supernova has, based on nucleosynthesis arguments, been modeled as an 8-10M star. Here we point out that the observations of the late light curve of SN 1054, from the historical records, are not compatible with the standard scenario, in which the late time emission is powered by the radioactive decay of small amounts of 56Ni. Based on model calculations we quantify this discrepancy. The rather large mass of 56Ni needed to power the late time emission, 0.06+0.02–0.03M, seems inconsistent with abundances in the Crab nebula. The late light curve may well have been powered by the pulsar, which would make SN 1054 unique in this respect. Alternatively, the late light curve could have been powered by circumstellar interaction, in accordance with scenarios in which 8-10M stars are progenitors to ``dense wind'' supernovae.
