Synopsis

Observations of the solar magnetic field are largely confined to the radiation emitted from the photosphere, the thin layer of the solar atmosphere which we call "the solar surface". It is from solar surface observations that we must infer the internal structure and the internal magnetohydrodynamic processes that lead to the multitude of fascinat- ing phenomena of solar magnetic activity, and from solar surface observations we must also infer the interplay of convection and magnetism that regulates field dispersal, drives the heating of the outer-atmospheric plasma, and generates the solar wind. There is much to be learned from solar surface magnetism in physics and astrophysics; currently, there are rapid developments in this exciting field. The workshop of which this volume contains the proceedings aimed at a synthesis between observers and theorists, both with regard to the discrete elements that are the building blocks of solar magnetism and with regard to the larger-scale spatial and temporal patterns in which the magnetic elements emerge and disappear. The workshop was held during November 1-5, 1993 in Soesterberg, The Netherlands. The fifty participants took a very active part in making the workshop quite a lively one. The articles in these proceedings cover most of the oral and poster presentations, excepting a dozen soon to be published elsewhere.

A propos du livre

Présentation de l'éditeur

While the emergence and evolution of solar surface magnetic flux reveals what goes on in the solar interior, the interplay of convection and magnetic field in the photosphere regulates the field dispersal and drives the instabilities which heat the outer solar atmosphere. The book presents a synthesis between observers and theorists, both with regard to the magnetic elements which make up solar magnetic fields (ranging from tiny flux tubes to whole active regions), and to the surface patterns in which these elements display properties of the subsurface dynamo. A major breakthrough comes from numerical simulations. Modeling of flux concentration, flux tube dynamics, penumbral topology, umbral fine structure, etc. turns solar physics into an experimental science. The reviews and research papers in this volume provide an up-to-date overview of the solar frontier of astrophysical magnetohydrodynamics.
The elements and patterns of solar surface magnetism contain much information about the subsurface solar dynamo as well as on the magnetically dominated energy budget and structuring of the outer solar atmosphere. The volume treats high-resolution solar polarimetry, the physics of solar magnetic elements, and the information contained in their patterns of emergence on the solar surface in depth, with a good balance between theoretical and observational studies.
