Magnetohydrodynamic Processes in Solar Plasmas provides a comprehensive theory and practice of basic plasma processes in the Sun and heliosphere. It deals with the basic dynamics of the Sun from its interior up to its outer atmosphere in the framework of Magnetohydrodynamics. Topics covered include essential phenomena in the solar interior such as

The age of a star cannot be measured but only inferred from observational quantities related to age. A wellknown stellar age greatly impacts our understanding of evolution on much larger scales, such as exoplanetary systems or the history of the Milky Way. For stars in the red-giant phase, comparison of observations with evolutionary models

Both Galactic dust emission and Cosmic infrared background anisotropies (CIB) act as a dominant foreground contaminant for the measurements of the CMB anisotropies (intensity and polarization) at the frequency range above 217 GHz. The Galactic dust and CIB share a similar form of spectral energy distribution, which makes it harder to disentangle
