Synopsis

The SOHO-7 Workshop was held from 28 September through 1 October 1998 at the Asticou Inn in Northeast Harbor, Maine. The primary topic of this Workshop was the impact of SOHO observations on our understanding of the nature and evolution of coronal holes and the acceleration and composition of the solar wind. The presentations and discussions occasionally went beyond this topic to include the impact of the reported research on other solar structures and the heliosphere. SOHO (the Solar and Heliospheric Observatory), a project of international cooperation between ESA and NASA, was launched in December 1995 and began its science operations during the first few months of 1996. To many solar and space physicists, it was a great advantage that SOHO began itscomprehensive look at the Sun during the 1996 solar minimum. The qualitatively simple two-phase corona, with polar coronal holes expanding into the high-speed solar wind, and a steady equatorial streamer belt related somehow to the stochastic slow-speed solar wind, allowed various SOHO diagnostics to be initiated with a reasonably well­ understoodcircumsolar geometry. The analysis of subsequentSOHO measurements made during the rising phase of solar cycle 23 will continue to benefit from what has been learned from the first two years of data.

About this title

Synopsis

The Proceedings of the SOHO-7 Workshop provide an overview of how observations with the Solar and Heliospheric Observatory (SOHO) have led to greater understanding about the nature and evolution of coronal holes and the acceleration of the solar wind. Coronal holes are regions of low density plasma on the Sun that have magnetic fields that expand freely into interplanetary space, and SOHO has allowed solar physicists to investigate the detailed physical processes responsible for maintaining this complex state.The SOHO-7 Workshop Proceedings focus on four topics: constraints by interplanetary and remote-sensing measurements on solar wind models; energy input, heating, and wind acceleration in coronal holes; coronal hole boundaries and adjacent regions; and, composition and elemental abundance variations. This book will be of use to the entire solar community by providing scientists with a concise summary of the progress SOHO has made in this field, and young researchers can use it to learn about the most relevant topics in this rapidly evolving discipline.
