Radio Measurements of the Magnetic Field in the Solar Chromosphere and the Corona

Frontiers in Astronomy and Space Sciences, 2021
The structure of the upper solar atmosphere, on all observable scales, is intimately governed by the magnetic field. The same holds for a variety of solar phenomena that constitute solar activity, from tiny transient brightening to huge Coronal Mass ...

Rapid Cooling After Device Annealing Suppresses Interface Losses in Cu2ZnSnS4 Solar Cells Enabling High Efficiency and Stability [PDF]

Advanced Science, EarlyView.
Rapid cooling after device annealing regulates the CdS/CZTS heterojunction and Mo/CZTS back contact, suppressing interfacial recombination and modifying the interfacial MoS2 layer, thereby enabling a 15.9% indoor PCE in pure‐sulfide CZTS solar cells.

On the mechanisms of sporadic solar radio emission [PDF]

Symposium - International Astronomical Union, 1959
The mechanism that generates sporadic (nonthermal) solar radio emission, which is of great interest to radio astronomy and solar physics, is rather obscure. Recently the authors considered this problem [1, 2, 3] and this report gives their summary.

Electromagnetic Simulations of Solar Radio Emissions [PDF]

Journal of Geophysical Research: Space Physics, 2019
AbstractSolar radio emissions are electromagnetic waves emitted in the solar wind as a consequence of electron beams accelerated during solar flares or interplanetary shocks such as interplanetary coronal mass ejections. Different physical mechanisms have been suggested to describe their origin. A good understanding of the emission process would enable

Latest results on Jovian disk X-rays from XMM-Newton [PDF]

, 2007
We present the results of a spectral study of the soft X-ray emission (0.2–2.5 keV) from low-latitude (‘disk’) regions of Jupiter. The data were obtained during two observing campaigns with XMM-Newton in April and November 2003.
