Opacity of Ejecta in Calculations of Supernova Light Curves
M. Sh. Potashov, S. I. Blinnikov, E. I. Sorokina
The plasma opacity in stars depends mainly on the local state of matter (the density, temperature, and chemical composition at the point of interest), but in supernova ejecta it al…
A Robust Light-Curve Diagnostic for Electron-Capture Supernovae and Low-Mass Fe-Core-Collapse Supernovae
Masato Sato, Nozomu Tominaga, Sergei I. Blinnikov +3
Core-collapse supernovae (CCSNe) are the terminal explosions of massive stars. While most massive stars explode as iron-core-collapse supernovae (FeCCSNe), slightly less massive st…
Analytical Model of Time-Dependent Ionization in the Envelopes of Type II Supernovae at the Photospheric Phase
M. Sh. Potashov, S. I. Blinnikov
We investigate a simplified kinetic system of the hydrogen atom (two levels plus continuum) under conditions of a type IIP supernova at the plateau phase that realistically describ…
Supernova 2018aoq and a distance to Seyfert galaxy NGC 4151
D. Yu. Tsvetkov, P. V. Baklanov, M. Sh. Potashov +9
We present optical photometric observations of SN 2018aoq from 2 to 100 days after explosion, and 7 spectra at epochs from 11 to 71 days. The light curves and spectra are typical f…
Time-Dependent Ionization in theEnvelopes of Type II Supernovae at the Photospheric Phase
M. Sh. Potashov, S. I. Blinnikov, V. P. Utrobin
The importance of allowance for the time-dependent effect in the kinetics at the photospheric phase during a supernova explosion has been confirmed by several independent research…
Direct Determination of Hubble Parameter Using Type IIn Supernovae
Sergei Blinnikov, Marat Potashov, Petr Baklanov +1
We introduce a novel approach, a Dense Shell Method (DSM), for measuring distances for cosmology. It is based on original Baade idea to relate absolute difference of photospheric r…
