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

UTROBIN V.P. and CHUGAI N.N.

Abstract (from CDS):

We present the hydrodynamic model of Type IIP SN 2020jfo with the unusually short (∼60 d) 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 pre-supernova wind density turns out highest among known SNe IIP. Yet the pre-supernova 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 d) 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.
