The Sun as a Prototype in the Study of Stellar Magnetic Activity,ise us ever since the telescope, and in particular the spectrograph, has been used to observe the Sun. Details show up down to scales below an arc- second, while future high-resolution telescopes probably hold more surprises in store. Not only the high degree of structuring is surprising, but also t

Hydrodynamics of the Solar Photosphere: Model Calculations and Spectroscopic Observations,ce (except for sunspots), the so called .. Bright isolated elements, the granules, are surrounded by a network of interconnected dark lanes. In contrast to W. Herschel, who first reported the existence of some small-scale inhomogeneities on the solar surface in 1801, we now have a basic physical und
