Infrared Solar Physics. [PDF]

Living Rev Sol Phys, 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

ADVANCEMENTS IN SOLAR NEUTRINO PHYSICS [PDF]

International Journal of Modern Physics E, 2013
We review the results of solar neutrino physics, with particular attention to the data obtained and the analyses performed in the last decades, which were determinant to solve the solar neutrino problem (SNP), proving that neutrinos are massive and oscillating particles and contributing to refine the solar models.

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 ...

Improved equivalent circuit and analytical model for amorphous silicon solar cells and modules [PDF]

, 1998
An improved equivalent circuit for hydrogenated amorphous silicon (a-Si:H) solar cells and modules is presented. It is based on the classic combination of a diode with an exponential current-voltage characteristic, of a photocurrent source plus a new ...
