| Abstract: |
SN 2023ixf is one of the closest supernovae discovered in the last decade. It was classified as a Type II supernova. In this presentation, we review light-curve properties of Type II supernovae and introduce a grid of Type II supernova light-curve models. By comparing the light-curve model grid to the observed light curve of SN 2023ixf, we estimated that SN 2023ixf has the progenitor mass of 10 M⊙, the explosion energy of 2 × 1051 erg, the 56Ni mass of 0.06 M⊙, the mass-loss rate of 10−2 M⊙ yr−1, the CSM density structure of β = 3, and the CSM radius of 5 × 1014 cm. In addition, long-lasting ultraviolet brightness of SN 2023ixf indicates that the progenitor had the mass-loss rate of 10−4 M⊙ yr−1 before it increased to 10−2 M⊙ yr−1 shortly before the explosion. |
