Infrared Solar Physics [PDF]

Living Reviews in Solar Physics, 2014
The infrared solar spectrum contains a wealth of physical data about our Sun, and is explored using modern detectors and technology with new ground-based solar telescopes. The scientific motivation behind exploring these wavelengths is presented, along with a brief look at the rich history of observations here. Several avenues of solar physics research

Kinetic Physics of the Solar Corona and Solar Wind [PDF]

Living Reviews in Solar Physics, 2006
Kinetic plasma physics of the solar corona and solar wind are reviewed with emphasis on the theoretical understanding of the in situ measurements of solar wind particles and waves, as well as on the remote-sensing observations of the solar corona made by means of ultraviolet spectroscopy and imaging.

Combining Empirical and Physics-Based Models for Solar Wind Prediction

Universe
Solar wind modeling is classified into two main types: empirical models and physics-based models, each designed to forecast solar wind properties in various regions of the heliosphere.

Review and comparison of MHD wave characteristics at the Sun and in Earth’s magnetosphere

Solar-Terrestrial Physics, 2022
Magnetohydrodynamic (MHD) waves play a crucial role in the plasma processes of stellar atmospheres and planetary magnetospheres. Wave phenomena in both media are known to have similarities and unique traits typical of each system.

Solar neutrinos: Solar physics and neutrino physics [PDF]

Nuclear Physics B - Proceedings Supplements, 1994
Abstract It is shown that the current solar neutrino situation, with results from the Homestake experiment, the Kamiokande experiment, GALLEX and SAGE is unfortunately still ambiguous. The differences between observations and the standard solar theory may still be due to either astrophysical inputs or new neutrino physics.

Turbulent parameters at different heights in the atmosphere. Shack–Hartmann wavefront sensor data

Solar-Terrestrial Physics, 2022
The paper presents the results of studies of wavefront distortions at different heights in the atmosphere. We have used measurement wavefront data to determine optical turbulence parameters along the line of sight of the Large Solar Vacuum Telescope ...

ISTP SB RAS decameter radars

Solar-Terrestrial Physics, 2020
Under the project National Heliogeophysical Complex of the Russian Academy of Sciences, it is planned to create several coherent decameter radars. ISTP SB RAS developed a network of coherent decameter radars well before the start of financing this ...

HF radio channel modeling by a waveguide approach

Solar-Terrestrial Physics, 2023
We present a modified method of HF radio channel modeling based on a waveguide approach. The waveguide approach represents the electromagnetic field of radiation inside the Earth—ionosphere waveguide as an eigenfunction series of a radial boundary ...

Characterising dye-sensitised solar cells [PDF]

, 2009
In today’s society there is a vast and in many cases not fully appreciated dependence on electrical power for everyday life. Furthermore, with growing energy and environmental concerns arising due to fossil fuel depletion and climate change/global ...
