Disturbed Flows in the Inner Solar Wind and Near Earth's Orbit
Pätzold, M.; Bird, M. K.; Efimov, A. I. +3 more
Coronal mass ejections from active regions on the Sun can be observed as series of individual events separated in time in the inner solar wind and near-Earth plasma. To find such events we have analyzed experimental data of dual-frequency solar wind radio sounding by the Rosetta and Mars Express spacecraft. The cycles of experiments performed in 2…
Observation of Disturbed Plasma Structures in the Environment of the Sun and Near-Earth Space with Radio Sounding and Local Measurements
Bird, M. K.; Efimov, A. I.; Lukanina, L. A. +3 more
An experiment on radio sounding of the circumsolar plasma by signals from the Mars Express spacecraft in 2013 was carried out in the period from March 4 through May 31. The investigated characteristics were the frequency of signals in the centimeter and decimeter ranges and the differential frequency. A number of events were recorded in which the …
Physical Mechanism of a Solar Flare Based on the Accumulation of the Energy in the Magnetic Field of the Current Sheet in the Solar Corona
Podgorny, I. M.; Podgorny, A. I.
During a solar flare, the magnetic energy of ~1032 erg is released in a few dozens of minutes. The invariability of the magnetic field on the solar surface during flares proves the appearance of a flare in the corona. An analysis of the dynamics of the electron temperature of the solar atmosphere provides independent evidence of the cor…
Current Sheets with Multicomponent Plasma in Magnetospheres of Planets of the Solar System
Popov, V. Yu.; Petrukovich, A. A.; Grigorenko, E. E. +2 more
A self-consistent hybrid model of a thin current sheet (TCS) with a thickness of the order of several ion gyroradii is proposed that takes into account the multicomponent nature of collisionless space plasma. Several plasma components can be present in the tails of the magnetospheres of terrestrial planets (for example, the Earth, Mercury, Mars, a…
Comparison of Magnetic and Plasma Overshoots of Interplanetary Shocks
Yermolaev, Yu. I.; Eselevich, V. G.; Zastenker, G. N. +2 more
The structure of interplanetary shock fronts was studied based on the data from the BMSW plasma spectrometer, installed on the SPEKTR-R spacecraft, supplemented by magnetic field measurements on the WIND spacecraft. Special attention was paid to periodic growths (overshoots) in the value of the ion flux or magnetic field relative to their mean val…
Comparing the Features of Generation of CMEs Moving with Different Speed in the Field of View of the LASCO Coronagraphs
Fainshtein, V. G.; Zagainova, Yu. S.
This study is aimed at finding an answer to the following question: are there any fundamental differences in the generation of coronal mass ejections (CMEs) with different speeds, especially low and high speeds, detected in the field of view of LASCO coronagraphs? Fast CMEs are conventionally understood as mass ejections with a linear projection v…
