Escape of planetary atmospheres: physical processes and numerical models

Shematovich, V. I.; Marov, M. Ya

We address the problem of the dissipation (escape) of planetary atmospheres and discuss the physical mechanisms controlling the nature of the relevant processes and review the mathematical models and numerical methods used in the analysis of this phenomenon, taking the limitations imposed by available experimental data into account. The structural…

Global structure of the heliosphere: 3D kinetic-MHD model and the interpretation of spacecraft data

Izmodenov, V. V.

This paper is a brief overview of research into the interaction between the solar wind and local interstellar medium. This interaction determines the global structure of the heliosphere (the region occupied by the solar wind) and has a complex multicomponent character. We describe the three-dimensional kinetic-magnetohydrodynamic model of the inte…

30 years of the Vega mission: Comparison of some properties of the 1P/Halley and 67P/Churyumov-Gerasimenko comets

Ksanfomality, L. V.

On March 6 and 9, 1986, for the first time in the history of science, the Russian spacecraft Vega-1 and Vega-2 approached and closely passed by the nucleus of Halley’s comet (1P/Halley). A few days later, on March 14, 1986, the same was done by the European Space Agency’s (ESA) Giotto spacecraft. These missions, together with the Japanese Suisei (…

Investigation of intermittency and generalized self-similarity of turbulent boundary layers in laboratory and magnetospheric plasmas: towards a quantitative definition of plasma transport features

Zelenyi, Lev M.; Budaev, V. P.; Savin, Sergei P.

A comparative analysis of the fundamental properties of fluctuations in the vicinity of boundaries in fusion plasmas and in plasmas of magnetospheric turbulent boundary layers (TBLs) shows the similarity of their basic statistical characteristics, including the scaling of the structure functions and mutifractal parameters. Important features obser…
