The spectral composition of the Sun’s output is not constant but varies over multiple timescales, from days to decadal cycles. Solar spectral irradiance variability (SSI) refers to the changes in the ...

Researchers developed a solar collector with a dielectric Bragg mirror, optimizing energy conversion by separating sunlight ...

Solar physics investigates the complex processes occurring in our Sun – the nearest star and a prototypical example of stellar activity. Central to the discipline is an understanding of the Sun’s ...
