The Solar $Hep$ Process [PDF]

, 2004
The $Hep$ process is a weak-interaction reaction, $He3 + p \to He4 + e^+ + \nu_e$, which occurs in the sun. There is renewed interest in $Hep$ owing to current experimental efforts to extract from the observed solar neutrino spectrum information on non ...

All-atmosphere IS-MST Radar

Solar-Terrestrial Physics, 2020
The IS-MST radar, as the name implies, combines two different methods for studying the atmosphere using a backscatter signal. Turbulent fluctuations of the medium cause scattering in the mesosphere—stratosphere—troposphere (MST). In the upper atmosphere,

Statistical relation of traveling ionospheric disturbances with neutral wind and disturbances in the stratosphere

Solar-Terrestrial Physics, 2022
Using the representative statistics on traveling ionospheric disturbances (TIDs) obtained by Yekaterinburg and Magadan radars, we have shown that distributions of TIDs and average TID velocities by azimuths and local time agree well with the hypothesis ...

Solar neutrino physics

Progress in Particle and Nuclear Physics, 2023
As a free, intensive, rarely interactive and well directional messenger, solar neutrinos have been driving both solar physics and neutrino physics developments for more than half a century. Since more extensive and advanced neutrino experiments are under construction, being planned or proposed, we are striving toward an era of precise and comprehensive

Solar models and solar neutrino oscillations [PDF]

, 2004
We provide a summary of the current knowledge, theoretical and experimental, of solar neutrino fluxes and of the masses and mixing angles that characterize solar neutrino oscillations.

Studying the dynamics of electric currents and polar caps in ionospheres of two hemispheres during the August 17, 2001 geomagnetic storm

Solar-Terrestrial Physics, 2019
The magnetogram inversion technique (MIT), developed at ISTP SB RAS more than forty years ago, has been used until recently only in the Northern Hemisphere.

CALIBRATION OF SIBERIAN RADIOHELIOGRAPH IMAGES

Solar-Terrestrial Physics, 2019
We discuss the method for automatic calibration of solar radio images derived from the first stage of the multiwave Siberian Radioheliograph (SRH-48). SRH is a 48-element T-shaped radiointerferometer in the 4–8 GHz frequency range. Since the end of 2017,

Estimation of the contributions of conductance and electric field to the intensity of field-aligned currents in the night polar ionosphere during substorm expansion phase

Геодинамика и тектонофизика, 2019
Based on the output data of the magnetogram inversion technique, we analyze the dynamics of the Pedersen ionospheric currents and field-aligned currents (FACs) in the night mesoscale cells of the three main large-scale Iijima and Potemra Regions (R1, R2 ...
