Evidence of Weak Circumstellar Medium Interaction in the Type II SN 2023axu

Evidence of Weak Circumstellar Medium Interaction in the Type II SN 2023axu

We present high-cadence photometric and spectroscopic observations of SN 2023axu, a classical Type II supernova with an absolute V -band peak magnitude of –17.2 ± 0.1 mag. SN 2023axu was discovered by the Distance Less Than 40 Mpc (DLT40) survey within 1 day of the last nondetection in the nearby ga...
