Based on this effect, we propose a new method to determine the photometric redshift from the SN IIP light curve in the U band. Using the STELLA code, we have constructed model light curves in different bands for different redshifts $z = 0.0, 0.1$, and $0.3$ as the metallicity in the models decreases from $Z \\sim 10^{-3}$ to $\\sim 10^{-6}$. The flux in the U band is shown to reach a plateau at the lowest metallicities. We consider the influence of other parameters as well: the presupernova mass and the mass of radioactive nickel-56.", "revisions": [ { "version": "v1", "updated": "2020-10-05T15:15:50.000Z" } ], "analyses": { "keywords": [ "plateau shape", "metallicity", "sn iip light curve", "dependence", "constructed model light curves" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
