SN 2016cvk light curves
Listed in IVOA Registry (Virtual Observatory)
The interacting transient SN 2016cvk (ASASSN-16jt) is a member of the peculiar SN 2009ip-like events.
Description
We present our follow-up data and aim to draw conclusions about the physical nature of the progenitor system. Our spectrophotometric data set of SN 2016cvk covers the ultraviolet, optical, and near-infrared wavelength region extending to +1681d from the light curve peak; the data is analysed and compared to other SN 2009ip-like transients.
Archival data reveals pre-outbursts of the progenitor with the first detection at -1219d. The light curve evolution of SN 2016cvk consists of two consecutive luminous events A and B with peak magnitudes of M_V_<-15.6 and M_r_=-18.3mag, respectively. The spectra are dominated by Balmer emission lines that have a complex, multi-component evolution similar to other SN 2009ip-like targets.

SN 2016cvk is among the first detected SN 2009ip-like events that show early 'flash ionisation' features of CIII, NIII, and HeII, lasting for 16+/-5d. Our late-time +405d spectrum shows forbidden [CaII], [FeII], and [OI] features with the latter detected particularly clearly for a SN 2009ip-like event. The evolution of SN 2016cvk is similar to other SN 2009ip-like transients, with some uncommon traits.
The lack of a double-peaked structure in the Balmer lines is likely caused by differences in the circumstellar medium structure or viewing angle. The flash features in the early spectra propose abundances consistent with a red, yellow, or blue supergiant progenitor rather than for example a luminous blue variable. The detection of [OI] in the +405d spectrum suggests possible evidence of nucleosynthesised material generated in a SN explosion.
