| 英文摘要 | We present photometric and spectroscopic observations of Type IIP supernova (SN IIP) SN 2023axu, spanning similar to 400 days after the explosion. Its light curve is typical of normal SNe IIP, with a V-band peak of -17.25 +/- 0.06 mag and no early time excess indicative of strong circumstellar interaction. The early spectra exhibit a distinctive broad ledge near 4600 & Aring;. Through spectral modeling and comparison, we attribute this feature to a blend of C, N, and He lines excited by weak interaction between the ejecta and a low-density stellar wind. The late-time photometric evolution shows no discernible contribution from interaction, arguing against strong late-time circumstellar material engagement and supporting the low-density wind scenario. From modeling, this supernova synthesized similar to 0.055 M circle dot of 56Ni and nebular spectrum analysis indicates a progenitor mass near 15 M circle dot. SN 2023axu thus exemplifies weak ejecta-wind interaction and highlights the diversity of mass-loss histories and circumstellar environments of SNe II progenitors. |
