SN 2023ixf is a type II supernova that exploded inside dense, confined circumstellar material lost by its red supergiant progenitor in the final years before explosion, as established by synthesizing over 80 published studies.

abstract
We used the LOFAR telescope to monitor SN 2023ixf, a core-collapse supernova in M101, between 8 and 368 days post-explosion. We report non-detections down to ~80 {\mu}Jy sensitivity at 144 MHz. Our non-detections are consistent with published radio observations at higher frequencies. At the time, we are not able to constrain the properties of low-frequency absorption due to the progenitor star's circumstellar medium via these LOFAR observations.
