Abstract: The Fast Blue Optical Transient (FBOT) AT 2022kmm has a light curve as bright as superluminous supernovae but rises and falls much faster. We reproduced this light curve using 2 models: circumstellar interaction of a pulsational pair-instability supernova (PPISN) model and 15 M ZAMS mass the star that has evolved to core-collapse that has experienced different extent of hydrogen envelop stripping Mass loss and progenitor properties from massive stars being as yet modelled, such work provides a direct estimate of the nature of the CSM, and the post-main sequence (post-MS) epoch at which it was created. The lightcurve will be modelled using SNEC, publicly available codes. Once the composition and the epoch of the CSM creation are modelled, we used MESA a stellar evolution code (with mass-loss introduced to account for CSM generation) to track the post-MS evolution of the progenitor star.
