Variable Stars As Essential Astrophysical Tools
de Turkey) NATO Advanced Study Institute on Variable(Ed. Springer) Isbn : 0792360834
341.95 €
Pulsating and eccentric binary stars play a fundamentally important role in deciphering the mass distribution within stars. The present volume reviews the fundamental concepts of both radial and nonradial oscillations in the stars, including the Sun. Helio- and astroseismological results are reviewed, from the basics to the most recent developments. A new theory is presented, which seems to explain the mechanism of the light and radial velocity variations of recently discovered Ap stars. This textbook covers almost all kinds of variable stars of widely different characteristics. It will serve as a reference text for a very long time to come, not only for specialists but also for undergraduate students of physics and astronomy.

The Atlantic Puffin
de David Boag, Mike Alexander(Ed. Blandford Pr) Isbn : 0713717343
17.66 €
Puffins are appealing, comical waterbirds of the far North with large, colorful beaks. This commendable book, though rich in authoritative detail, is a popularly written work filled with interesting anecdotes, and illustrated with 70 color photos. Appendixes detail special photo-techniques for above and under water, and maps show breeding areas. This is a fine title for those who do not need the exhaustive treatment of M.P. Harris's excellent The Puffin (Buteo Bks., 1984). Both books have a British orientation, since the authors are English and most puffin research is done in the U.K. Boag is the author of another species life history, The Kingfisher , which was well received. The Atlantic Puffin deserves a wide readership. Highly recommended. Henry T. Armistead, Thomas Jefferson Univ. Lib...
