Giants of Eclipse: The zeta Aurigae Stars and Other Binary Systems

Buch

The zeta Aurigae stars are the rare but illustrious sub-group of binary stars that undergo the dramatic phenomenon of chromospheric eclipse. This book provides detailed descriptions of the ten known systems, illustrates them richly with examples of new spectra, and places them in the context of stellar structure and evolution.Comprised of a large cool giant plus a small hot dwarf, these key eclipsing binaries reveal fascinating changes in their spectra very close to total eclipse, when the hot star shines through differing heights of the chromosphere, or outer atmosphere, of the giant star. The phenomenon provides astrophysics with the means… Mehr

Über den Autor


For many years Dr Griffin pursued research into stellar spectra, principally of composite-spectrum binaries, at Cambridge (UK), supporting it with observations acquired at major telescopes overseas. She now continues those interests in Canada, at the Dominion Astrophysical Observatory near Victoria, and makes her observations there. The prime research objectives are to determine the masses and other fundamental parameters of both component stars, and to examine their evolutionary status. She also champions initiatives to recover the information in pre-digital (photographic) observations through programmes of appropriate digitization.Dr. Ake is a Program Director at Computer Sciences Corporation supporting the Hubble Space Telescope, the James Webb Space Telescope, the Milkulski Archive for Space Telescopes, and the Kepler Data Management Center projects at Space Telescope Science Institute. His research interests center on evolved stars and binary systems, particularly UV and FUV spectroscopic investigations from space of red giants and supergiants with hot secondary companions. He is currently studying the evolutionary status of cool stars with main sequence B- and A-type secondaries to refine the fundamental stellar parameters of the evolved components.
