The Physics of the Solar Corona and Transition Region / Edition 1

by Oddbjorn Engvold, C.J. Schrijver, John W. Harvey, Neal E. Hurlburt

Overview

Solar Physics publishes up to two Topical Issues per year that focus on areas of especially vigorous and active research. The present Topical Issue contains papers of recent results on the solar corona, as well as on the transition region and low solar wind. The majority of these papers, which were all refereed in accordance with the standards of Solar Physics, were presented in August 1999 at a workshop held in Monterey, California. The authors were offered the opportunity to present relevant parts of their contributions on an accompanying CD ROM of this Topical Issue. The Sun's magnetic field is responsible for the spectacularly dynamic and intri­ cate phenomenon that we call the corona. The past decade has seen an enormous increase in our understanding of this part of the solar outer atmosphere, both as a result of observations and because of rapid advances in numerical studies. The Yohkoh satellite has observed the Sun now for over eight years, producing spectac­ ular sequences of images that convey the complexity of the corona. The imaging and spectroscopic instruments on SOHO have added information on the cooler part of the corona. And since April of 1998 TRACE has given us very high resolution images of the 1-2 MK corona, at cadences that allow detailed observations of field oscillations, loop evolution, mass ejecta, etc.

Editorial Reviews

Thirty papers comprise one of the two volumes which resulted from the August 1999 workshop. The papers revolve around one key theme: the entire outer atmosphere of the sun is intrinsically dynamic, evolving so rapidly that even the concept of a single local temperature for a single fluid often breaks down. In addition, the corona is an intrinsically nonlinear and non-local medium. Topics of the papers include: aspects of three-dimensional magnetic reconnection; long- lived coronal loops observed by TRACE; high-resolution observations of plasma jets in the solar corona; time variability of EUV brightenings in coronal loops observed by TRACE; radio versus EUV/X-ray observations of the solar atmosphere; and measuring the physical properties of the solar corona: results from SUMER/SOHO and TRACE.
