Paperback. Condizione: New. Print on Demand. This book presents a detailed account of the author's efforts to determine the aberration constant using meridian circle observations of the star Polaris. Meridian circles were used by astronomers in the past to measure precise zenith distances of stars, and the author encountered several challenges in using this instrument, including accounting for the division errors, exure, and refraction. The author provides a wealth of observational data and discusses the methods used to reduce and analyze it. This book will be of interest to historians of astronomy and to anyone interested in the history of astronomical instrumentation and observing techniques. It provides valuable insights into the challenges faced by astronomers in the past and the methods they used to overcome them. 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. …

Taschenbuch. Condizione: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - The book ''Transactions Of The Detroit Observatory, Part 1: Determination Of The Aberration Constant From Zenith Distances Of Polaris, Measured With The Walker Meridian Circle (1904)'' by Asaph Hall Jr. is a scientific publication that focuses on the determination of the aberration constant from zenith distances of Polaris. The book is part of the Transactions of the Detroit Observatory series and was originally published in 1904.The author, Asaph Hall Jr., was an American astronomer who worked at the United States Naval Observatory and the Lowell Observatory. He is best known for his discovery of the two moons of Mars, Phobos and Deimos.In this book, Hall Jr. describes the methodology used to measure the aberration constant from the zenith distances of Polaris, which is the brightest star in the constellation Ursa Minor. The measurements were made using the Walker Meridian Circle, which is a type of astronomical instrument used to measure the positions of celestial objects.The book includes detailed descriptions of the equipment and techniques used in the measurements, as well as tables and graphs of the data collected. The results of the study are presented and analyzed, and the author draws conclusions about the accuracy of the measurements and the value of the aberration constant.Overall, ''Transactions Of The Detroit Observatory, Part 1: Determination Of The Aberration Constant From Zenith Distances Of Polaris, Measured With The Walker Meridian Circle (1904)'' is a valuable resource for astronomers and anyone interested in the history of astronomical measurement techniques.This scarce antiquarian book is a facsimile reprint of the old original and may contain some imperfections such as library marks and notations. Because we believe this work is culturally important, we have made it available as part of our commitment for protecting, preserving, and promoting the world's literature in affordable, high quality, modern editions, that are true to their original work.…
