Measures of Proper Motion Stars Made With the 40-Inch Refractor of the Yerkes Observatory in the Years 1907 to 1912 (Classic Reprint) - Couverture souple
Synopsis
This book presents a collection of stellar measurements made with the 40-inch refractor of the Yerkes Observatory in the years 1907 to 1912. The author, an accomplished observer, measured over 9500 stars, focusing primarily on those identified as having proper motion. Proper motion is the change in position of a star over time, and it can be caused by several factors, including the movement of the star itself, the rotation of the Milky Way galaxy, and the expansion of the universe. The author's measurements provide valuable data for astronomers studying the motions of stars and the structure of our galaxy. This book contributes to our understanding of stellar astronomy and serves as a valuable resource for researchers in the field.
