Dynamics of the level of total electron content disturbance at high and middle latitudes according to GPS data

Solar-Terrestrial Physics, 2016
We study the level of total electron content (TEC) disturbance in ionospheric mid-latitude and high-latitude regions, which occurred during 2013. TEC behavior is calculated using data from two GPS stations: MOND (Mondy) and NRIL (Norilsk). TEC variations

Long-lived meteor trails

Solar-Terrestrial Physics, 2019
The paper presents data on long-lived (~20–40 min) meteor trails. We describe a group of soliton-type meteor trails expanding at transonic speeds. Radio sounding data evidences that the latter include ~7–8 min ionization trails.

Physics of solar-like oscillations [PDF]

Solar Physics, 2004
AbstractThe physics of solar and stellar oscillations determine their observable characteristics. I provide a brief overview of the properties of solar-like oscillations, excited by stochastic processes, in other stars. In addition, I consider the current state of investigations of such oscillations, as well as the prospects for an improved ...

Photometrical observations and shape modeling of space debris in medium Earth orbits

Solar-Terrestrial Physics
The circular medium Earth orbits with a period of about half a day in the inclination range from 50° to 70° are used by various global navigation satellite systems (GNSS), such as GLONASS, GPS, Beidou, Galileo.

Solar Neutrino Physics [PDF]

, 1999
With its heavy water target, the Sudbury Neutrino Observatory (SNO) offers the unique opportunity to measure both the 8B flux of electron neutrinos from the Sun and, independently, the flux of all active neutrino species reaching the Earth. A model-independent test of the hypothesis that neutrino oscillations are responsible for the observed solar ...

LONG-TERM SOLAR FLUX OBSERVATIONS WITH IRKUTSK INCOHERENT SCATTER RADAR (IISR) IN 2011–2019

Solar-Terrestrial Physics, 2020
Irkutsk incoherent scatter radar (IISR) is an oblongish horn antenna that operates in a meter waveband (154–162 MHz), has a 0.5°×20° beam, and a frequency steering allowing us to tilt the beam by 30° to the south.

Astroparticle physics with solar neutrinos

Proceedings of the Japan Academy, Series B, 2011
Solar neutrino experiments observed fluxes smaller than the expectations from the standard solar model. This discrepancy is known as the "solar neutrino problem". Flux measurements by Super-Kamiokande and SNO have demonstrated that the solar neutrino problem is due to neutrino oscillations.
