I am most grateful to Andr' e Heck for his invitation to write a foreword to OSA Volume 4 - I will use this valued opportunity to emphasise those topics in Vol.
The Imager for Magnetopause-to-Aurora Global Exploration (IMAGE) is a NASA Explorer mission that is the first space mission dedicated to imaging of the Earth's magnetosphere.
This volume contains a series of lectures presented at the 4th Course of the International School of Astrophysics, held in Erice (Sicily) from July 9 - July 20, 1977 at the "e;E.
The aim of the present book will be to provide a comprehensive account of our present knowledge of the theory of dynamical phenomena exhibited by elose binary systems; and on the basis of such phenomena as have been attested by available observations to outline probable evolutionary trends of such systems in the course of time.
(Opening Address of 13th ESLAB Symposium) With GEOS and ISEE occupying a major part of the ESA scientific programme it was clear several years ago that a 'natural' basis for the 1978 ESLAB Annual Symposium would be the early data from these two spacecraft.
The purpose of this textbook is to provide a basic knowledge of the main parts of modern astrophysics for all those starting their studies in this field at the undergraduate level.
Eclipsing Variables - What They can Tell Us and What We can do with Them The aim of the present book will be to provide an introduction to the inter- pretation of the observed light changes of eclipsing binary stars and their analysis for the elements of the respective systems.
The rapid evolution of technology and mathematical methods in this century has led to the recognition and accumulation of a large quantity of scientific facts.
Informal discussions in 1977 among a number of scientists asso- ciated with solar and interplanetary physics revealed a need for a dialogue between the two often-divergent groups.
This volume contains a series of lectures presented at the 5th Course of the International School of Astrophysics held in Erice (Sicily) from July 1st to July 14, 1979 at the "e;E.
Since their first detection 15 years ago, radio recombination lines from several elements have been observed in a wide variety of objects including HII regions, planetary nebulae, molecular clouds, the diffuse interstellar medium, and recently, other galaxies.

In recent years, it has become clear that the red-giant phase is one of the most dramatic periods in a star's life, when all of its parts become involved in ways that have both direct and indirect observational consequences.
Our conference - opening today - has two aims in view: first, to commemorate some milestones in the development of the studies of close binary systems whose anniversaries fall in these years, as well as to take stock of our present knowledge accumulated through- out preceding decades, in order to consider where do we go from here.
This book represents the proceedings of a NATO Advanced Study Institute which was held at Bonas from August 25 till Sep- tember 5, 1980 and was devoted to the study of "e;Solar Phenomena in Stars and Stellar Systems"e;.
The meeting of the High Energy Astrophysics Division of the American Astronomical Society, held in Cambridge, Massachusetts on January 28- 30, 1980, marks the coming of age of X-ray astronomy.
This is the latest effort in a sequence of presentations begun in 1949 with a series of lectures on long-focus photographic astrometry given by the author as Fulbright professor in Paris at the invitation by the late H.
Interest world-wide in the provision of new observational astro- nomical facilities in the form of ground-based optical telescopes of large aperture has never been higher than exists at present.
The symposium on "e;Neutral Clouds near HII Regions"e; was prompted by an obvious need to bring together workers specifically interested in the dynamical and photochemical effects in regions showing clear evidence of on-going star formation.
When we first approached some colleagues allover the world to sound them about a volume dedicated to Professor John Xanthakis on the occasion of completing twenty-five years of scientific activities as fellow of the National Academy of Athens, any possible doubts as to the feasibility of the project were quickly dispelled by their warm and encouraging response.
Radio techniques were the nrst to lead astronomy away from the quiescent and limited Universe revealed by traditional observations at optical wave- lengths.
