Magnetodynamic Phenomena In The Solar Atmosphere

These are the Proceedings of Colloquium No. 153 of the International Astro nomical Union, held at Makuhari near Tokyo on May 22 - 26, 1995, and hosted by the National Astronomical Observatory. This meeting was intended to be an interdisciplinary meeting between re searchers of solar and stellar activity, in order for them to exchange the newest information in each field. While each of these areas has seen remarkable advances in recent years, and while the researchers in each field have felt that information from the other's domain would be extremely useful in their own work, there have not been very many opportunities for intensive exchanges of information between these closely related fields. We therefore expected much from this meeting in pro viding stellar researchers with new results of research on the counterparts of their targets of research, spatially and temporarily resolved, as observed on the Sun. Likewise we hoped to provide solar researchers with new results on gigantic ver sions of their targets of research under the very different physical circumstances on other active stars. It was our greatest pleasure that we had wide attendance of experts and active researchers of both research fields from all over the world. This led to extremely interesting talks and very lively discussions, thereby stimulating the exchange of ideas across the fields.

M. KITAMURA Tokyo Astronomical Observatory, Japan and E. BUDDING Carter Observatory, Wellington, New Zealand The Third Asian-Pacific Regional Meeting of the International Astronomical Union was held from 30 September to 5 October, 1984, at the Kyoto International Conference Hall, Kyoto, Japan, under the auspices of the Union and the Astronomical Society of Japan with Kyoto University as host. Three hundred and twenty-seven astronomers from twenty-two countries participated at the meeting and more than two hundred papers were presented. The aim of the meeting was not only to promote scientific developments and cooperation, but also to offer a chance for all participants to become acquainted with major astronomical projects of the Asian-Pacific Region. Therefore, two new sessions of 'A View of Asian-Pacific Astronomy' and 'Astronomical Education in the Asian Pacific Region', which had not been undertaken in the previous two Regional Meetings, were arranged as a first trial, besides the other ordinary scientific sessions. The Scientific Organizing Committee consisted of D.C. Morton (chairman), R.N. Manchester, S.M. Gong, K.J. Feng, C.S. Shen, J.C. Bhattacharyya, G. Swa B. Hidayat, H.M.K. AI-Nairniy, H.S. Yun, J.B. Hearnshaw, S.C. Wolff, I. Ka rup, waguchi, M. Kitamura, M. Morimoto, M. Oda, andJ. P. Swings (IAU, ex officio); and the Local Organizing Committee of T. Kogure (chairman), T.lshizawa, M. Saite, R. Hirata, S.lnagaki, E. Hiei, M. Kitamura, B. Takase, N. Kaifu, H. Maehara, Y. Osaki, and A. Yamasaki.

Second edition graduate level textbook giving an up-to-date treatment of our understanding of the solar corona.

The aim of this Advanced Study Institute was to give an account on the most recent results obtained in solar research. Bucharest was chosen to host it, because the capital city of Romania was located right in the middle of the totality path of the last eclipse of the millennium, on 11th August 1999; furthermore the phenomenon was close to reach there its longest duration: 2m 23s. Such a total eclipse is not only a very spectacular event which draws the crowds: to astronomers, solar eclipses still offer the best conditions for observing the lower part of the corona. The Sun plays a crucial role in our very existence. It was responsible for the formation of the Earth, and rendered this planet fit to host living beings, providing the right amount of heat, and this for a long enough span of time. Quite understandably, it has always been a prime target of human curiosity, and more recently one of scientific investigation. During the last century, it was realized that the Sun is a star like billions of others; we learned since that it draws its energy from the nuclear fusion of hydrogen, and we are now able to estimate its age and life expectancy.

A comprehensive account of solar astrophysics and how our perception and knowledge of this star have gradually changed as mankind has elucidated ever more of its mysteries. The emphasis here is on the last decade, which has seen three successful solar spacecraft missions: SOHO, Ulysses and Yohkoh. Together, these have confirmed many aspects of the solar standard model and provided new clues to the numerous open questions that remain. The author, a leading researcher in the field, writes in a clear and concise style. Known also for his famous books "Astrophysical Formulae", "Sun, Earth and Sky" and the prize-winning "Wanderers in Space", he has succeeded once again in addressing a complex scientific topic in a very approachable way.

Since its launch in 1991, the Yohkoh satellite has been returning unprecedented observations of solar flares and the dynamic solar corona. This book is a collection of papers presented at a meeting held in: Yoyogi, Tokyo, on the occasion of Yohkoh's fifth anniversary of operation. The papers constitute a summary of observations and results over the five years, including contributions based on data from Yohkoh's hard and soft X-ray telescopes and its spectrometer experiments. The five years of data, covering approximately one-half of a solar cycle, reveal a fresh perspective on solar science, with a new picture of solar flares and the active Sun emerging. Also, for the first time there are extensive results from Yohkoh observations of the Sun during the solar minimum period. This wide-ranging volume will be of interest to workers in solar physics and X-ray astronomy. It also contains material appropriate for supplemental reading for graduate students in solar physics.
