Lightcurves of thermonuclear supernovae as a probe of the explosion mechanism and their use in cosmology
S. Blinnikov, E. Sorokina
Thermonuclear supernovae are valuable for cosmology but their physics is not yet fully understood. Modeling the development and propagation of nuclear flame is complicated by numer…
Shock breakouts in SNe Ib/c
S. I. Blinnikov, D. K. Nadyozhin, S. E. Woosley +1
Numerical modeling of shock breakout in compact presupernovae of type Ib/c is done by two independent methods. Peak color temperatures reach 4 to 8 million K for explosion energies…
Global Monopole in General Relativity
Kirill A. Bronnikov, Boris E. Meierovich, Evgeny R. Podolyak
We consider the gravitational properties of a global monopole on the basis of the simplest Higgs scalar triplet model in general relativity. We begin with establishing some common…
A Thickness of Stellar Disks of Edge-on Galaxies and Position of Their Truncation Radii
A. V. Zasov, D. V. Bizyaev
The relationship between the geometrical properties of stellar disks (a flatness and truncation radius) and the disk kinematics are considered for edge-on galaxies. It is shown tha…
Gas Flow Structure in Binary Systems with Mass Exchange Driven by Stellar Wind
A. A. Boyarchuk, D. V. Bisikalo, E. Yu. Kilpio +1
Results of calculations of the flow structure in binary systems with mass exchange driven by stellar wind are presented. 2D simulations have been carried out using the Roe-Oscher s…
Energy exchange inside SN ejecta and light curves of SNe Ia
E. I. Sorokina, S. I. Blinnikov
A treatment of line opacity in expanding medium is most crucial for the light curve (LC) modeling of Type Ia supernovae (SNe Ia). Spectral lines are the main source of opacity insi…
