Uncommon SN 2020jfo: Ordinary explosion of 8 M⊙ red supergiant with dense wind

Abstract We present the hydrodynamic model of Type IIP SN 2020jfo with the unusually short (∼60 days) light curve plateau. The model suggests the explosion of ≈8 M⊙ red supergiant that ejected ≈6 M⊙ with the energy of ≈0.8 × 1051 erg. The presupernova wind density turns out highest among known SNe IIP. Yet the presupernova was not embedded into a very dense confined circumstellar shell that is a feature of some Type IIP supernovae, so the circumstellar interaction in close environment does not contribute noticeably to the initial (∼10 days) bolometric luminosity. Despite uncommon appearance SN 2020jfo turns out similar to SN 1970G in the V-band light curve, photospheric velocities, and, possibly, luminosity as well.
