Advances in Astronomy and Astrophysics, Volume 9 covers reviews on the advances in astronomy and astrophysics. The book presents reviews on the Roche model and its applications to close binary systems. The text then describes the part played by lunar eclipses in the evolution of astronomy; the classical theory of lunar eclipses; deviations from geometrical theory; and the methods of photometric observations of eclipses. The problems of other phenomena related in one way or another to lunar eclipses are also considered. The book further tackles the infrared observation on the eclipsed moon, as well as some of the experimental measurements at infrared wavelengths which have proved useful in evaluating various theoretical models and, more generally, in specifying the radiation environment on the lunar surface. Astronomers, astrophysicists, and students taking related courses will find the book invaluable.
