Light curves of the explosion of ONe WD+CO WD merger remnant and type Icn supernovae
arxiv(2024)
摘要
Type Icn supernovae (SNe Icn) are a newly detected rare subtype of
interacting stripped-envelope supernovae which show narrow P-Cygni lines of
highly ionized carbon, oxygen, and neon in their early spectra due to the
interactions of the SNe ejecta with dense hydrogen- and helium-deficient
circumstellar material (CSM). It has been suggested that SNe Icn may have
multiple progenitor channels, such as the explosion of carbon-rich Wolf-Rayet
stars, or the explosion of stripped-envelope SNe which undergo binary
interactions. Among the SNe Icn, SN 2019jc shows unique properties, and
previous work inferred that it may stem from the ultra-stripped supernova, but
other possibilities still exist. In this work, we aim to simulate the light
curves from the explosions of oxygen-neon and carbon-oxygen double white dwarf
(WD) merger remnants, and to further investigate whether the corresponding
explosions can appear as some particular SNe Icn. We generate the light curves
from the explosive remnants and analyse the influence of different parameters
on the light curves, such as the ejecta mass, explosion energy, mass of Ni56
and CSM properties. Comparing our results with some SNe Icn, we found that the
light curves from the explosions of double WD merger remnants can explain the
observable properties of SN 2019jc, which inferred that this special SN Icn may
have a different progenitor. Our results indicated that double WD merger may be
an alternative model in producing at least one of the SNe Icn.
