SN 2023ixf in M101: Physical Parameters from Bolometric Light Curve Modeling
Abstract We present new photometric observations of the core-collapse supernova SN 2023ixf occurred in M101, taken with the RC 80 and BRC80 robotic telescopes in Hungary. The initial nickel mass from the late-phase bolometric light curve extending up to 400 days after explosion, is inferred as M Ni = 0.046 ± 0.007 M ⊙ . The comparison of the bolometric light curve with models from hydrodynamical simulations as well as semi-analytic radiative diffusion codes reveals a relatively low-mass ejecta of M ej ≲ 9 M ⊙ , contrary to SN 2017eaw, another H-rich core-collapse event, which had M ej ≳ 15 M ⊙ .
