Dynamics of direct impact accretion in degenerate binary systems
Nikita Kramarev, Andrey Yudin
We consider the gas dynamics in an accreting binary system of degenerate stars within the framework of the Newtonian approximation. In such a system, the accretion stream can impac…
A simple model of time-dependent ionization in Type IIP supernova envelopes
M. Sh. Potashov, A. V. Yudin
We propose a model kinetic system of the hydrogen atom (two levels plus continuum) under the conditions typical for atmospheres of Type IIP supernovae in the plateau stage. Despite…
Hydrostatic equilibrium of stars without electroneutrality constraint
M. I. Krivoruchenko, D. K. Nadyozhin, A. V. Yudin
The general solution of hydrostatic equilibrium equations for a two-component fluid of ions and electrons without a local electroneutrality constraint is found in the framework of…
Variational Principle for Stars with a Phase Transition
A. V. Yudin, T. L. Razinkova, D. K. Nadyozhin
The variational principle for stars with a phase transition has been investigated. The term outside the integral in the expression for the second variation of the total energy of a…
Some properties of convection in hybrid stars
A. V. Yudin, M. Hempel, D. K. Nadyozhin +1
It is shown that the unusual thermodynamic properties of matter within the region of two-phase coexistence in hybrid stars result in a change of the standard condition for beginnin…
Excluded-Volume Approximation for Supernova Matter
A. V. Yudin
A general scheme of the excluded-volume approximation as applied to multicomponent systems with an arbitrary degree of degeneracy has been developed. This scheme also admits an all…
Special point on the mass radius diagram of hybrid stars
A. V. Yudin, T. L. Razinkova, D. K. Nadyozhin +1
An analytical study that explains the existence of a very small region on the mass radius diagram of hybrid stars where all of the lines representing the sequences of models with d…
Principal Physical Effects in Collapsing Stellar Cores
D. K. Nadyozhin, A. V. Yudin
Principally important for the description the physical processes in the collapsing stellar cores topics are surveyed. They are: the neutrino heat conduction theory, equation of sta…
