Unstable gas flow in a flat channel under the influence of a transverse force field: self-oscillations of the jet

Autor: Korolkov, S. D., Izmodenov, V. V.

A subsonic flow of an ideal gas through a flat channel in the presence of a mass force field is considered. The forces acting on the gas are reduced to the attraction to the channel axis in a certain region of the channel. It has been shown that the

The global structure of astrospheres: effect of Knudsen number

Autor: Korolkov, S. D., Izmodenov, V. V.

The interaction between stellar winds and the partially ionized local interstellar medium (LISM) is quite common in astrophysics. However, the main difficulty in describing the neutral components lies in the fact that the mean free path of an interst

Stabilization of the astropause by periodic fluctuations of the stellar wind

Autor: Korolkov, S. D., Izmodenov, V. V.

Publikováno v: Monthly Notices of the Royal Astronomical Society, 2023, 518

The main goal of the paper is to explore why observations of many astrospheres (or circumstellar bubbles) show quite stable and smooth structures of astropauses - the tangential discontinuities separating the stellar and interstellar winds, - while b

Shock-wave heating mechanism of the distant solar wind: explanation of Voyager-2 data

Autor: Korolkov, S. D., Izmodenov, V. V.

Publikováno v: A&A 667, L5 (2022)

One of the important discoveries made by Voyager-2 is the nonadiabatic radial profile of the solar wind proton temperature. This phenomenon has been studied for several decades. The dissipation of turbulence energy has been proposed as the main physi
