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 of
analyzing the outer atmosphere of a giant star and how that
material is shed into space. The physics of these critical events
can be explained qualitatively, but it is more challenging to
extract hard facts from the observations, and tough to model the
chromosphere in any detail. The book offers current thinking on
mechanisms for heating a star's chromosphere and on how a star
loses mass, and relates this science synergistically to studies of
other stars and binaries, and to the increasing relevance of
contributions from new techniques in interferometry and
asteroseismology. It also includes a detailed discussion of the
enigmatic star epsilon Aurigae, which had recently undergone one of
its very infrequent and very baffling eclipses. Though not a zeta
Aurigae system, epsilon Aurigae is a true "Giant" among eclipsing
stars. The 7 chapters of this book, written by a group of experts,
have been carefully edited to form a coherent volume that offers a
thorough overview of the subject to both professional and student.
