Abstract (from CDS):

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 M☉ of 56Ni, ejecta mass Mej=1.4–0.5+1.3M☉, and kinetic energy Ek=0.7–0.3+0.6×1051 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☉, suggesting a binary scenario.
