Double Star Publications: 1939-1959

A collection of detailed observations of 'double stars' made by a variety of Universities and Goverment agencies. As descibed by wikipedia:

"In observational astronomy, a double star is a pair of stars that appear close to each other in the sky as seen from Earth when viewed through an optical telescope. This can happen either because the pair forms a binary star, i.e. a binary system of stars in mutual orbit, gravitationally bound to each other, or because it is an optical double, a chance alignment of two stars in the sky that lie at different distances. Binary stars are important to stellar astronomers as knowledge of their motions allows direct calculation of stellar mass and other stellar parameters."

The collection includes journals published by Chicago University, the Union of South Africa, the United States Naval Observatory, and the University of Pennsylvania, to name only a few, all rebound into one large volume. The book is in very good condition. There is minor wear and scuffing to the top and bottom of the spine and moderate scuffing on the bottom of the rear board.
