Abstract

We present new photometric observations of the core-collapse supernova SN 2023ixf occurred in M101, taken with the RC80 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_{\rm Ni} = 0.046 ± 0.007 M_\odot. 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_{\rm ej} \lesssim 9 M_\odot, contrary to SN~2017eaw, another H-rich core-collapse event, which had M_{\rm ej} \gtrsim 15 M_\odot.
