Highlights of Astronomy, 1989 AbstractThis review discusses winds from stars with hot outer atmospheres, stars with coronae similar to the sun. It illustrates how solar observations can be used to test a theoretical model for solar-stellar winds, and thereby provide some insights concerning applications to studying winds from stars other than the sun.

Photosynthetic Active Radiation, Solar Irradiance and the CIE Standard Sky Classification
Applied Sciences, 2020 Plant growth is directly related to levels of photosynthetic photon flux density, Qp. The improvement of plant-growth models therefore requires accurate estimations of the Qp parameter that is often indirectly calculated on the basis of its relationship ...

The influence of solar wind variability on magnetospheric ULF wave power [PDF]
, 2015 Magnetospheric ultra-low frequency (ULF) oscillations in the Pc 4–5 frequency range play an important role in the dynamics of Earth's radiation belts, both by enhancing the radial diffusion through incoherent interactions and through the coherent drift ...
