Helium superluminous SN 2021bnw: an explosion of a massive star with a pre-outburst

These files present models built for explaining He-rich SLSN 2021bnw. The uploaded models cover a wide range of ejecta masses and CSM masses, although only some of them are the best-fit models, which match the pseudo-bolometric LC of SLSN 2021bnw. The models XXXd5XXX are built for the main LC. The models XXXd01XXX are built to explain the first data points of the SLSN 2021bnw LC. Details on each given model can be received by request. Details of the best-fit models are listed in Table 1 https://arxiv.org/abs/2602.15255
