Riassunto

For some time to come, this book should be the main source for research in prominences. It surveys the results of the past years, including the "Hvar Reference Atmosphere", which was developed by a panel as a model for quiescent prominences. The reader will find papers on the formation of and physical conditions in prominences, on magnetic fields, on mass motion and energy flow, and on the prominence-corona interface.
