Literature 1976, Part 2


Book Description

Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is de voted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documentation of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, com pared to which our system of accumulating abstracts for about six months offers the advantage of greater convenience for the user. Volume 18 contains literature published in 1976 and received before March 1, 1977; some older liter ature which was received late and which is not recorded in earlier volumes is also included.




The Motion of the Moon,


Book Description

The passage of the Moon across the night sky has long been a familiar, but mysterious, sight to man. Newton, with his laws of motion and inverse square law of gravity, was able to predict all the planetary orbits, at least in principle. However, an exact solution of the Moon's motion in the gravitational fields of the Sun and Earth defeated Newton and all his successors. The Motion of the Moon is a comprehensive account of the theoretical developments right up to the present day. All astronomers, physicists and mathematicians interested in the Moon will find this a very stimulating book.







Physics and Astronomy of the Moon


Book Description

Physics and Astronomy of the Moon focuses on the application of principles of physics in the study of the moon, including perturbations, equations, light scattering, and photometry. The selection first offers information on the motion of the moon in space and libration of the moon. Topics include Hill's equations of motion, non-solar perturbations, improved lunar ephemeris, optical and physical libration of the moon, and adjustment of heliometric observations of the moon's libration. The text then elaborates on the dynamics of the earth-moon system, photometry of the moon, and polarization of moonlight. The publication explains lunar eclipses and the topography of the moon. Discussions focus on the photometric model of eclipses, brightness of the solar elementary ring, effects of light scattering, photometry of lunar eclipses, and determination of altitudes on the moon. The text then evaluates the interpretation of lunar craters, luminescence of the lunar surface, and the origin and history of the moon. The selection is a dependable reference for physicists and astronomers interested in the application of principles of physics in the study of the moon.




The Hill-Brown Theory of the Moon’s Motion


Book Description

This book, in three parts, describes three phases in the development of the modern theory and calculation of the Moon's motion. Part I explains the crisis in lunar theory in the 1870s that led G.W. Hill to lay a new foundation for an analytic solution, a preliminary orbit he called the "variational curve." Part II is devoted to E.W. Brown's completion of the new theory as a series of successive perturbations of Hill's variational curve. Part III describes the revolutionary developments in time-measurement and the determination of Earth-Moon and Earth-planet distances that led to the replacement of the Hill–Brown theory in 1984.
