Observations of Variable Stars (Classic Reprint)
Print on DemandDa: Forgotten Books, London, Regno Unito
Valutazione del venditore 5 su 5 stelle
Paperback. Condizione: New. Print on Demand. This book collects variable star data and results derived from the extensive research of the author. It is a detailed, if traditional, contribution to the field of variable star observation and analysis. The author uses a large number of observations, collected over several years, to derive new elements for many stars and examine the question of period change in long-period variables. The work is embedded in the context of earlier variable star observations, with comparisons to earlier researchers like HARTWIG and others. It also considers in some depth the topic of period changes, especially in long-period variables, which, at the time of the author's writing, was still a relatively new and not well understood phenomenon. The ideas and data presented lay the groundwork for future researchers, providing a valuable historical record. 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. Codice articolo 9780259104780_0
