Abstract

Interacting supernovae provide key insights into the mass-loss processes of massive stars and their circumstellar environments. By analyzing their photometric and spectroscopic properties, we can study the complex interactions between ejected material and circumstellar material (CSM). This paper highlights the diversity of interacting SNe, including Types IIn, Ibn, and Icn, and explores the challenges in understanding progenitor systems, CSM structures, and late-time evolution. Advances in high-cadence observations and modeling are crucial for improving our knowledge of these stellar explosions.
