Paperback. Condición: New. Print on Demand. This book makes important contributions to the field of astronomy by presenting a thorough examination of double stars as physical or optical multiple-star systems, and delineating the types that exist. Statistical analyses, including angular distances, movements and properties are giv…en, offering a critique of existing double-star catalogues. The author's research focuses on the identification of double-star systems, distinguishing between those which are physically connected and those which only appear to be close together from our perspective. The book elucidates the criteria that define a 'real' physical pair, which involve the study of their combined motions and astrometric observations. Additionally, the author examines the history of astronomy, the evolution of knowledge about double and multiple stars, and the current state of research. The book provides a vital resource for astronomers seeking a comprehensive understanding of double and multiple stars in our galaxy. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
