SN 2016iyc: a Type IIb supernova arising from a low-mass progenitor

ABSTRACT In this work, photometric and spectroscopic analyses of a very low-luminosity Type IIb supernova (SN) 2016iyc have been performed. SN lies near the faint end among distribution similar supernovae (SNe). Given lower ejecta mass (Mej) low nickel (MNi) from literature, combined with lying end, one-dimensional stellar evolution models 9–14 M? zero-age main-sequence (ZAMS) stars as possible progenitors performed using publicly available code mesa. Moreover, synthetic explosions progenitor simulated, hydrodynamic codes stella snec. The bolometric luminosity light curve photospheric velocities produced through ZAMS in range 12–13 having pre-supernova radius R0 = (204–300) R?, Mej (1.89–1.93) M?, explosion energy Eexp (0.28–0.35) × 1051 erg, MNi < 0.09 are good agreement observations; thus, probably exploded limits for SNe IIb. Finally, simulations 2016gkg 2011fu also to compare intermediate- high-luminosity examples well-studied results modelling 2016iyc, 2016gkg, exhibit diverse
