Abstract

The subject of this lecture is the origin of the solar corona, but I would like to begin with a brief recollection of the basic ideas on which present concepts of solar and stellar activity are based. First of all, there is the star itself, first represented by Emden’s gaskügeln. His simple polytrope models are the first scientific representation of the static equilibrium of a self-gravitating star. The polytropes are not precise models of a star, but they capture the basic theoretical principles of the balance of thermal pressure against gravity, with a high central temperature declining toward the surface.
