On the observational behaviour of the highly polarized Type IIn supernova SN 2017hcc

Abstract

We present the results based on photometric ($Swift$ UVOT), broad-band polarimetric ($V$ and $R$-band) and optical spectroscopic observations of the Type IIn supernova (SN) 2017hcc. Our study is supplemented with spectropolarimetric data available in literature for this event. The post-peak light curve evolution is slow ($\sim$0.2 mag 100 d${}^{-1}$ in $b$-band). The spectrum of $\sim$+27 d shows a blue continuum with narrow emission lines, typical of a Type IIn SN. Archival polarization data along with the $Gaia$ DR2 distances have been utilized to evaluate the interstellar polarization (ISP) towards the SN direction which is found to be $P_{ISP}$ = 0.17 $\pm$ 0.02 per cent and ${\theta }_{ISP}$ = 140${}^{\circ }$ $\pm$ 3${}^{\circ }$. To extract the intrinsic polarization of SN 2017hcc, both the observed and the literature polarization measurements were corrected for ISP. We noticed a significant decline of $\sim$3.5 per cent ($V$-band) in the intrinsic level of polarization spanning a period of $\sim$2 months. In contrast, the intrinsic polarization angles remain nearly constant at all epochs. Our study indicates a substantial variation in the degree of asymmetry in either the ejecta and/or the surrounding medium of SN 2017hcc. We also estimate a mass-loss rate of $\dot{M}$ = 0.12 M${}_{\odot }$ yr${}^{-1}$ (for $v_w$ = 20 km s${}^{-1}$) which suggests that the progenitor of SN 2017hcc is most likely a Luminous Blue Variable.
