Progenitor mass of the type IIP supernova 2005cs
V. P. Utrobin, N. N. Chugai
The progenitor mass of type IIP supernova can be determined from either hydrodynamic modeling of the event or pre-explosion observations. To compare these approaches, we determine…
Circumstellar Na I and Ca II lines in type IIP supernovae and SN 1998S
N. N. Chugai, V. P. Utrobin
We study a possibility of detection of circumstellar absorption lines of Na I D and Ca II H,K in spectra of type IIP supernovae at the photospheric epoch. The modelling sho…
Ejecta and progenitor of the low-luminosity Type IIP supernova 2003Z
V. P. Utrobin, N. N. Chugai, A. Pastorello
The origin of low-luminosity Type IIP supernovae is unclear: they have been proposed to originate either from massive (about 25 Msun) or low-mass (about 9 Msun) stars. We wish to d…
An optimal hydrodynamic model for the normal Type IIP supernova 1999em
V. P. Utrobin
There is still no consensus about progenitor masses of Type IIP supernovae. We study a normal Type IIP SN 1999em in detail and compare it to a peculiar Type IIP SN 1987A. We comput…
Strong effects of time-dependent ionization in early SN 1987A
V. P. Utrobin, N. N. Chugai
We study a time-dependent hydrogen ionization in the atmosphere of SN 1987A during the first month after the explosion. The model includes kinetics of hydrogen ionization and excit…
The Light Curve of Supernova 1987A: The Structure of the Presupernova and Radioactive Nickel Mixing
V. P. Utrobin
We have studied the influence of the presupernova structure and the degree of Ni-56 mixing on the bolometric light curve of SN 1987A in terms of radiation hydrodynamics in the one-…
