الوصف: | We present the detailed optical evolution of a type Ib SN 2015dj in NGC 7371, using data spanning up to $\sim$ 170 days after discovery. SN 2015dj shares similarity in light curve shape with SN 2007gr and peaks at M$_{V}$ = $-17.37\pm$0.02 mag. Analytical modelling of the quasi bolometric light curve yields 0.06$\pm$0.01 M$_{\odot}$ of $^{56}$Ni, ejecta mass $M_{\rm ej} = 1.4^{+1.3}_{-0.5}$ \msol\, and kinetic energy $E_{\rm k} = 0.7^{+0.6}_{-0.3} \times 10^{51}$ erg. The spectral features show a fast evolution and resemble those of spherically symmetric ejecta. The analysis of nebular phase spectral lines indicate a progenitor mass between 13-20 M$_{\odot}$ suggesting a binary scenario. Comment: 16 pages, 11 figures, accepted for publication in ApJ |
