Excerpt from On the Systematic Motions of the K-Stars
All these directions we indicate by arrows and these arrows we move parallel to themselves to the centre of the region.
If the stars do not prefer any direction of motion, the arrows will be regularly divided over the 360° encircling the centre.

Verkäuferbewertung 4 von 5 Sternen
Paperback. Zustand: New. Print on Demand. This book takes an in-depth look at the two main methods of investigating the proper motions of stars: Kapteyn's method and Eddington's method. The author makes a theoretical study of Eddington's method with the purpose of finding out to what extent the method can be applied in practice. To investigate this, the author makes a comparison of the results obtained from Eddington's method with the results already published by other authors. These results show that the number of stars used in the investigation is 1,420; the antivertices for the two star streams explored in the study are found to be: Drift I: RA 275o, Decl. -16o; Drift II: RA 95o, Decl. -12o; the true vertices for these streams are found to be: Drift I: RA 55o, Decl. 25o; Drift II: RA 235o, Decl. 30o; and the velocity of the solar motion towards the center of gravity of the stars used in the computation is found to be 20 km/sec. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format. In rare cases, an imperfection in the original, such as a blemish or missing page, may be replicated in the book. print-on-demand item. Bestandsnummer des Verkäufers 9781334031113_0
