Circumstellar interaction models for the early bolometric light curve of SN 2023ixf

Understand

SNe II show growing evidence of interaction with CSM surrounding their progenitor stars as a consequence of enhanced mass loss during the last years of the progenitor's life.

• We present an analysis of the progenitor mass-loss history of SN2023ixf, a nearby SN II showing signs of interaction.
• We calculate the early-time bolometric light curve (LC) for SN2023ixf based on the integration of the observed flux covering UV, optical and NIR bands, and black-body extrapolations for the unobserved flux.
• Our calculations spot the sudden increase to maximum luminosity and temperature, in addition to the subsequent fall, displaying an evident peak.
