On a discontinuity at the base of the transition layer located between the Keplerian accretion disk and the compact object
Lev Titarchuk, Ilia Kalashnikov
We study the geometry of the transition layer (TL) between the classical Keplerian accretion disk (the TL outer boundary) and the compact object at the TL inner boundary. Our goal…
Influence of dark matter on gravitational stability of isothermal gas clouds
I. Yu. Kalashnikov, V. M. Chechetkin
To date, the presence of dark matter (DM) can be judged only by its gravitational interaction on the visible matter. It is therefore important to find the consequences of this inte…
On the emergence of a new instability during core-collapse of very massive stars
I. Kalashnikov, A. Baranov, P. Chardonnet +2
The process of uniform supernovae explosions (SNe) is well investigated for all their types. However, observational data suggests that the SNe could be not spherically-symmetric. M…
The collimated propagation causes of astrophysical and laboratory jets
I. Kalashnikov, A. Dodin, I. Il'ichev +2
The use of Z-pinch facilities makes it possible to carry out well-controlled and diagnosable laboratory experiments to study laboratory jets with scaling parameters close to those…
Propagation dynamics of successive emissions in laboratory and astrophysical jets and problem of their collimation
I. Kalashnikov, P. Chardonnet, V. Chechetkin +2
The paper presents the results of numerical simulation of the propagation of a sequence of plasma knots in laboratory conditions and the astrophysical environment. The physical and…
Analytic description of anomalous diffusion in heterogeneous environments: Fokker-Planck equation without fractional derivatives
Ilia Kalashnikov, Polina Likhomanova
We present a model of diffusion in heterogeneous environment, which qualitatively reflects the transport properties of a polymeric membrane with carbon nanotubes. We derived Fokker…
Stability of Hartmann flow with the convective approximation
I. Yu. Kalashnikov
This research is focused on linear analysis of a plane-parallel flow stability in a transverse magnetic field (Hartmann flow) within a convective approximation. We derive and solve…
