- W4307564008 abstract "We present optical photometric and spectroscopic analysis of a Type Iax supernova (SN) 2020rea situated at the brighter luminosity end of Type Iax supernovae (SNe). The light curve decline rate of SN~2020rea is $Delta$m$_{15}$(g) = 1.31$pm$0.08 mag which is similar to SNe 2012Z and 2005hk. Modelling the pseudo bolometric light curve with a radiation diffusion model yields a mass of $^{56}$Ni of 0.13$pm$0.01 M$_{odot}$ and an ejecta mass of 0.77$^{+0.11}_{-0.21}$ M$_{odot}$. Spectral features of SN~2020rea during the photospheric phase show good resemblance with SN 2012Z. TARDIS modelling of the early spectra of SN~2020rea reveals a dominance of Iron Group Elements (IGEs). The photospheric velocity of the Si {sc II} line around maximum for SN~2020rea is $sim$ 6500 km s$^{-1}$ which is less than the measured velocity of the Fe {sc II} line and indicates significant mixing. The observed physical properties of SN~2020rea match with the predictions of pure deflagration model of a Chandrasekhar mass C-O white dwarf. The metallicity of the host galaxy around the SN region is 12+log(O/H) = 8.56$pm$0.18 dex which is similar to that of SN 2012Z." @default.
