Binaries as Tracers of Stellar Formation
More than two-thirds of stars belong to multiple stellar systems. Binary stars are considered now as one of the best constraints on stellar formation models. Not only do binaries keep memory of their birth conditions but their orbit will also be subjected to changes by tidal effects, wind accretion and encounters in clusters. Certainly the correlation between orbital eccentricity and period is a clue to our understanding of double star history. These proceedings aim to disentangle evidence of stellar formation from later physical evolution. Each article in this 1992 volume is a paper that was read at a meeting organized to honour Dr Roger Griffin of the University of Cambridge for his pioneer work in galactic astronomy, dynamics of clusters and study on binary stars due to his cross-correlation technique to determine stellar radial velocities.
Science's Most Wanted
Science and technology have had more than their share of the good, the bad, and the bogus. Alfred William Lawson, the designer of the first airliner, believed that two types of creatures lived within the brain Menorgs, A which were the mental organizers responsible for all good things, and Disorgs, A which infect all cells with disorganization. Chonosuke Okamura collected and catalogued what he thought were tiny men and animals, all 1/100-inch long, which most geologists think are actually mineral grains. Peter Fong found that the expression happy as a clamA had a scientific basis when he tested the effects of Prozac on fingernail clams. The dashing figure of dinosaur hunter Roy Chapman Andr...

Dynamics of Young Star Clusters and Associations
Where do most stars (and the planetary systems that surround them) in the Milky Way form? What determines whether a young star cluster remains bound (such as an open or globular cluster), or disperses to join the field stars in the disc of the Galaxy? These questions not only impact understanding of the origins of stars and planetary systems like our own (and the potential for life to emerge that they represent), but also galaxy formation and evolution, and ultimately the story of star formation over cosmic time in the Universe. This volume will help readers understand our current views concerning the answers to these questions as well as frame new questions that will be answered by the Euro...

Distant Wanderers
Recent discoveries of planet-like objects circling other sun-like stars have stirred enormous interest in what other planets may exist in the universe, and whether they could support intelligent life. This book takes us into the midst of this search for extrasolar planets. Unlike other books, it focuses on the people behind the searches -- many known personally by the author -- and the extraordinary technology that is currently on the drawing boards. The author is an experienced, award-winning science journalist who was previously technology correspondent for the Financial Times of London. He has written on many topics in astronomy and astrobiology in over 35 different newspapers and magazines worldwide.

One of Ten Billion Earths
Illustrated with breathtaking images of the Solar System and of the Universe around it, this book explores how the discoveries within the Solar System and of exoplanets far beyond it come together to help us understand the habitability of Earth, and how these findings guide the search for exoplanets that could support life. The author highlights how, within two decades of the discovery of the first planets outside the Solar System in the 1990s, scientists concluded that planets are so common that most stars are orbited by them. The lives of exoplanets and their stars, as of our Solar System and its Sun, are inextricably interwoven. Stars are the seeds around which planets form, and they prov...
