Abstract (from CDS):

We present the photometric and spectroscopic studies of a Type Ib SN 2015ap and a Type Ic SN 2016P. SN 2015ap is one of the bright (M_V = -18.04 mag) Type Ib while SN 2016P lies at an average value among the Type Ic SNe (M_V = -17.53 mag). Bolometric light-curve modelling of SNe 2015ap and 2016P indicates that both the SNe are powered by ⁵⁶Ni + magnetar model with ⁵⁶Ni masses of 0.01 and 0.002 M_☉, ejecta masses of 3.75 and 4.66 M_☉, spin period P₀ of 25.8 and 36.5 ms, and magnetic field B_p of 28.39 x 10¹⁴ and 35.3 x 10¹⁴ G, respectively. The early spectra of SN 2015ap show prominent lines of He with a 'W' feature due to Fe complexes while other lines of Mg II, Na I, and Si II are present in both SNe 2015ap and 2016P. Nebular phase [O I] profile indicates an asymmetric profile in SN 2015ap. The [O I]/[Ca II] ratio and nebular spectral modelling of SN 2015ap hint towards a progenitor mass between 12 and 20 M_☉.
