dc.description.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 Mv = −17.37 ± 0.02 mag. Analytical modeling of the quasi bolometric light curve yields 0.06 ± 0.01 Mʘ of 56Ni, ejecta mass Mej= -M 1.4 +1.3 -0.5, and kinetic energy Ek = E 0.7^+0.6^-0.3 x 10^51 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 Mʘ, suggesting a binary scenario.	en_US
