The secular evolution of the stellar rotation through angular momentum loss, driven by the stellar wind, and the consequences of the angular momentum transfers between orbit and spinning components in binary star systems will be reviewed with the special emphasis on the Solar rotation.

Solar Physics, 2017
Regular measurements of the general magnetic field of the Sun, performed over about half a century at the Crimean Astrophysical Observatory, the J. Wilcox Solar Observatory, and five other observatories, are considered in detail for the time 1968 – 2016. They include more than twenty-six thousand daily values of the mean line-of-sight field strength of

The Differential Solar Rotation
1994Theory and observations of the solar differential rotation are reviewed, concentrating on recent developments. Reynolds stresses produced by stratified rotating turbulence have recently become available as fully nonlinear functions of the angular velocity. A model based on this theory has reproduced the solar rotation; almost no tuning of the theory to

The constraint on transport processes derived from chemical abundances lead to low values of the diffusion coefficient (D ≃ 300) whereas the constraint derived from the transport of vorticity lead to high values (D ≃ 105). A brief discussion of the meaning of this discrepancy is given.

Solar Rotation: The interaction of Rotation and Convection
1973After having considered the principal observational evidence of rotation, the general hydrodynamic problem is set out from a theoretical point of view. In particular, the authors analyse the theories considering differential rotation as an effect due to the interaction of rotation and convection, pointing out the different proposed mechanism of angular

The rotation of the solar atmosphere
Solar Physics, 1969A model of the solar atmosphere is presented in which we discuss the conservation of angular momentum for the two basic states in which the solar gas can be: namely, either confined by closed field lines or outflowing along open magnetic field lines. It can be shown that the boundary conditions are in general different for these two cases. From this we

The Rotation of the Solar Core
2009In order to get a unified representation of stars, one needs to introduce the internal dynamical processes in the stellar structure equations. The validation of these complex equations supposes a proper reproduction of the helioseismic observations. Indeed the helioseismic discipline can provide today a crucial insight into the solar internal rotation ...

The helioseismic determination of the angular velocity distribution within the sun is discussed. In particular, the bulk of the radiative interior of the sun is rotating at more-or-less the same rate as the photosphere. The latitudinal variation of angular velocity appears to change quite abruptly immediately beneath the base of the convection zone ...

The subject of solar rotation, or more properly rotations, has become of considerable interest in the last few years. These new developments are primarily associated with spacecraft observations, including observations of the interplanetary medium near the earth, and with improved ground-based solar telescopes and digital data-handling facilities.
