In the past decade, indirect (Doppler) imaging techniques have opened up a whole new discipline in stellar astronomy, providing increasingly detailed photometric, magnetic, and chemical inhomogeneity images of stellar surfaces. Furthermore, new optical interferometers are already being used with sophisticated interferometer techniques to image stellar surface structures more directly, and in the future the ESO VLT Interferometer and other instruments will extend these capabilities enormously. These developments are highlighted in the first two sections of this book.
The large number of...

The Physics of Solar and Stellar Coronae provides the first comprehensive summary of the physical processes and phenomena occurring in solar and stellar coronae as observed at X-ray and other wavelengths. The book provides an early summary of the spectacular new solar X-ray observations being obtained with the Yohkoh satellite that are dramatically changing our understanding of the dynamics of the solar corona. With the perspective of two years' observations at X-ray and extreme ultraviolet wavelengths by the ROSAT satellite, many authors present new insights into the basic physical processes...

Recent research on the solar-stellar system has been triggered by a host of recent observational data, in particular from space based observations. For this conference the major topics selected centered on new measurement capabilities (magnetic fields and infrared, with specific emphasis on the new IRAS results), important classes of stars (F stars, M dwarfs and giants, and pre-main sequence stars), and interesting unanswered questions (the nature of nonthermal phenomena, heating processes, angular momentum evolution, and the existence and cause of the corona/wind dividing line). Each section...
