ELlA M. LEIBOWITZ Director, Wise Observatory Chair, Scientific Organizing Committee The international symposium on "Astronomical Time Series" was held at the Tel Aviv University campus in Tel Aviv, from December 30 1996 to January 11997. It was organized in order to celebrate the 25th anniversary of the Florence and George Wise Observatory (WO) operated by Tel Aviv University. The site of the 1 meter telescope of the observatory is near the town of Mitzpe-Ramon, some 220 km south of Tel Aviv, at the center of the Israeli Negev highland. There were two major reasons for the choice of Time...

The idea of having a conference in Padova describing the results obtained by the Galileo spacecraft and the characteristics of the Telescopio Nazionale Galileo began in 1995, when a number of colleagues from both sides of the Atlantic began exchanging suggestions and ideas. Looking at the schedules of the two teams, it was clear that the beginning of January 1997 would be a good time to hold the conference; these dates also luckily coincided with the dates of the memorable discovery of the Medicean moons of Jupiter by Galileo Galilei in Padova in 1610. To emphasize these three elements, the...

At the beginning of the 20th century, Kristian Birkeland (1867-1917), a Norwegian scientist of insatiable curiosity, addressed questions that had vexed European scientists for centuries. Why do the northern lights appear overhead when the earth s magnetic field is disturbed? How are magnetic storms connected to disturbances on the sun? To answer these questions Birkeland interpreted his advance laboratory simulations and daring campaigns in the Arctic wilderness in the light of Maxwell s newly discovered laws of electricity and magnetism. Birkeland s ideas were dismissed for decades, only...

LEFEUVRE 1 Chair of ESWW2, editor 2 co-Chair of ESWW2 This book presents Space Weather review papers given as invited presentations at the Second European Space Weather week which was held at the European Space Agency s ESTEC site in Noordwijk, The Netherlands, from 14th to 19th November, 2005. As the meeting itself, it is divided into 5 chapters, each representing one of the Science to Applications sessions on a particular theme. These themes are: Session 1: The solar weather/solar activity...

This is quite simply the first volume of its kind dedicated to the area of high time resolution astrophysics. High time resolution astrophysics (HTRA) is an important new window on the universe and a vital tool in understanding a range of phenomena from diverse objects and radiative processes. Underlining this science foundation, technological developments in both instrumentation and detectors are described.

The book introduces the solar coronal mass ejection phenomena. This includes both those observed in the corona and those further from the Sun, known as interplanetary coronal mass ejections. We discuss the history and physics behind these phenomena, theories describing their launch and evolution, association with other solar eruptive phenomena, and methods employed for their detection and scientific data extraction. Instruments used for their study (past, present and future) are also discussed, along with their resulting space weather effects on Earth and other planets. The latter requires a...

Radio telescopes as well as communication antennas operate under the influence of gravity, temperature and wind. Among those, temperature influences may degrade the performance of a radio telescope through transient changes of the focus, pointing, path length and sensitivity, often in an unpredictable way. Thermal Design and Thermal Behaviour of Radio Telescopes and their Enclosures reviews the design and construction principles of radio telescopes in view of thermal aspects and heat transfer with the variable thermal environment; it explains supporting thermal model calculations and the...

Solar flares are very complex electromagnetic phenomena of a cataclysmic nature. Particles are accelerated to very high velocities and a variety of physical processes happen inside and outside flares. These processes can be studied by a large number of techniques from Earth and from space. The aim is to discover the physics behind solar flares. This goal is complicated because information about the flare mechanism can be obtained only in an indirect way by studying the secondary effects. This book provides three stages in the solution of the solar flare problem. Chapter one describes...

In 1988, in an article on the analysis of the measurements of the variations in the radial velocities of a number of stars, Campbell, Walker, and Yang reported an - teresting phenomenon;the radial velocity variations of Cephei seemed to suggest the existence of a Jupiter-like planet around this star. This was a very exciting and, at the same time, very surprising discovery. It was exciting because if true, it would have marked the detection of the ?rst planet outside of our solar system. It was surprising because the planet-hosting star is the primary of a binary system with a separation less...

The problem of the composition of cosmic dust grains has stubbornly defied solution for over half a century. A succession of models have been proposed and their properties worked out for comparison with an ever-expanding body of relevant observational data. The authors began their pioneering work in this field in the 1960s by challenging the then popular ice grain theory. Most controversially they later hypothesised that condensed organic matter in the galaxy is of biological origin, thus linking an old astronomical problem with the question of the origin of terrestrial life. In this book the...
