Abstract
We present the detailed optical evolution of a Type Ib SN 2015dj in NGC 7371, using data spanning up to ∼170 days after discovery. SN 2015dj shares similarity in light-curve shape with SN 2007gr and peaks at M V = -17.37 0.02 mag. Analytical modeling of the quasi bolometric light curve yields 0.06 0.01 M o˙ of 56Ni, ejecta mass M o˙, and kinetic energy erg. The spectral features show a fast evolution and resemble those of spherically symmetric ejecta. The analysis of nebular phase spectral lines indicates a progenitor mass between 13-20 M o˙, suggesting a binary scenario.
