Paperback. Condizione: New. Print on Demand. This book presents insights into the solar rotation period by analyzing the motions of calcium flocculi, yielding a deeper understanding of solar physics. The author uses innovative techniques to measure the movement of these flocculi over time, revealing that they exhibit an equatorial acceleration akin to that observed in sunspots and other solar phenomena. By studying the calcium flocculi, this book contributes to the ongoing discourse on solar rotation and the behavior of various solar features, providing valuable information for astronomers and those interested in the complexities of our star. 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.…

Paperback. Condizione: New. Print on Demand. This book examines the rotation period of the Sun using measurements from the motions of the Sunâs calcium flocculi. The author begins by explaining the history of the three methods used to study the Sunâs rotation period: first, measuring the motion of the spots in longitude; second, measuring the motion of the faculae in longitude; and third, the method used in this book, measuring the motion in line of sight of the approaching and receding limbs. The main, central portion of this book focuses on the authorâs groundbreaking method of studying the rotation period of the Sun, which analyzes the motions of the calcium flocculi. After gathering data showing the movement of calcium flocculi over time, the author painstakingly analyzed the data, taking into account sources of error and using graphical methods. The book then compares the author's findings, yielding a rotation period for different latitudes, with previous research on sunspot motions, faculae motions, and the reversing layer. These three phenomena all exhibit an equatorial acceleration, a finding supported by the authorâs research with calcium flocculi. The author concludes that the Sunâs rotation period, as measured by the motions of different phenomena, varies with latitude.
