Résumé

The study of magnetic structure and activity in cool stars is largely inspired by the Sun. In the Sun the magnetic field has been concentrated in discrete elements which form a sequence, from the large dark sunspots down to the bright small elements in the magnetic network. The field strengths range from 3 kilo-gauss in sunspot umbrae to about 1.5 kilogauss in the network elements (for reviews, see Harvey, 1977 and Zwaan, 1980). This sequence may be explained by a set of magnetostatic flux tube models which depend on the magnetic flux through the tube (for a summary and references, see Zwaan, 1978). A basic assumption in the magnetostatic modeling is that the energy flux within the flux tube is no more than 20% of the energy flux in the nonmagnetic convection zone.
