Available in PDF, EPUB and Kindle. Book excerpt: There are many theories of the large-scale circulation of the sun. Fundamental to many of these is a meridional cell which transports momentum between the pole and equator. Observational verification has devolved most often upon the analysis of the latitudinal drifts of sunspots. A comprehensive analysis of sunspot drifts shows some peculiar results. Two conclusions can be drawn from these results. First, sunspot data cannot be used to verify the existence of a mean meridional circulation on the sun. Second, the residual meridional drifts (averaged over time and longitude) are very much smaller than their day-to-day counterparts, lending support to the idea that the latter are the more fundamental to the large-scale solar circulation.

Book Synopsis Nature's Third Cycle by : Arnab Rai Choudhuri
Download or read book Nature's Third Cycle written by Arnab Rai Choudhuri and published by Oxford University Press, USA. This book was released on 2015 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: The cycle of day and night and the cycle of seasons are two familiar natural cycles around which many human activities are organized. But is there a third natural cycle of importance for us humans? On 13 March 1989, six million people in Canada went without electricity for many hours: a large explosion on the sun was discovered as the cause of this blackout. Such explosions occur above sunspots, dark features on the surface of the Sun that have been observed through telescopes since the time of Galileo. The number of sunspots has been found to wax and wane over a period of 11 years. Although this cycle was discovered less than two centuries ago, it is becoming increasingly important for us as human society becomes more dependent on technology. For nearly a century after its discovery, the cause of the sunspot cycle remained completely shrouded in mystery. The 1908 discovery of strong magnetic fields in sunspots made it clear that the 11-year cycle is the magnetic cycle of the sun. It is only during the last few decades that major developments in plasma physics have at last given us the clue to the origins of the cycle and how the large explosions affecting the earth arise. Nature's Third Cycle discusses the fascinating science behind the sunspot cycle, and gives an insider's perspective of this cutting-edge scientific research from one of the leaders of the field.

This book was released on 2013-06-29 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: The message of sunspots from the interior of the Sun to the Earth's climate When Galileo was summoned before the Inquisition on April 12, 1633, the main accusations laid against him concerned the doubts he expressed about Aristotle's theory of the universe. Aristotle's idea was that the Earth was the centre of the cosmos and that all of the stars, including the Sun, turned around it. Moreover, for Aristotle and the world of the Inquisitors, the Sun was a perfect celestial body. Now, Galileo had discovered spots on the Sun. These spots were seen as imperfections, and not just surface markings, but coming from within the Sun. Worse yet, they revolved around the Sun. All this supported the newfangled theory of Copernicus, and undermined a system of thought that had reigned supreme for centuries. Man of science that he was, and a prudent Catholic too, Galileo strived all his life to prove that Copernicus' astronomical concept was compatible with the word of the Bible. He proposed that there were not two truths but a single divine truth. It was just expressed in two different languages : there was the language of the common people, with its imprecision and inconsistencies, but intuitively understandable by everyone; and then there was the precise language of science with its strict regard for observation, which only a chosen few can grasp [L. Geymonat. 1992].
Book Synopsis Theory of Rotating Stars. (PSA-1), Volume 1 by : Jean-Louis Tassoul
Download or read book Theory of Rotating Stars. (PSA-1), Volume 1 written by Jean-Louis Tassoul and published by Princeton University Press. This book was released on 2015-03-08 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ever since the first observations of sunspots in the early seventeenth century, stellar rotation has been a major topic in astronomy and astrophysics. Jean-Louis Tassoul synthesizes a large number of theoretical investigations on rotating stars. Drawing upon his own research, Professor Tassoul also carefully critiques various competing ideas. In the first three chapters, the author provides a short historical sketch of stellar rotation, the main observational data on the Sun and other stars on which the subsequent theory is based, and the basic Newtonian hydrodynamics used to study rotating stars. Following a discussion of some general mechanical properties of stars in a state of permanent rotation, he reviews the main techniques for determining the structure of a rotating star and its stability with respect to infinitesimal disturbances. Since the actual distribution of angular momentum within stars is still unknown, Professor Tassoul considers various models of angular momentum as well as of meridional circulation. He devotes the rest of his study to the problems concerning various groups of stars and stages in stellar evolution. Originally published in 1979.

Book Synopsis The Earth's Atmosphere by : Kshudiram Saha
Download or read book The Earth's Atmosphere written by Kshudiram Saha and published by Springer Science & Business Media. This book was released on 2008-05-14 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author has sought to incorporate in the book some of the fundamental concepts and principles of the physics and dynamics of the atmosphere, a knowledge and understanding of which should help an average student of science to comprehend some of the great complexities of the earth-atmosphere system, in which a thr- way interaction between the atmosphere, the land and the ocean tends to maintain an overall mass and energy balance in the system through physical and dynamical processes. The book, divided into two parts and consisting of 19 chapters, introduces only those aspects of the subject that, according to the author, are deemed essential to meet the objective in view. The emphasis is more on clarity and understanding of physical and dynamical principles than on details of complex theories and ma- ematics. Attempt is made to treat each subject from ?rst principles and trace its development to present state, as far as possible. However, a knowledge of basic c- culus and differential equations is sine qua non especially for some of the chapters which appear later in the book.

Download or read book Physics of the Sun written by Dermott J. Mullan and published by CRC Press. This book was released on 2022-09-13 with total page 435 pages. Available in PDF, EPUB and Kindle. Book excerpt: With an emphasis on numerical modelling, Physics of the Sun: A First Course presents a quantitative examination of the physical structure of the Sun and the conditions of its extended atmosphere. It gives step-by-step instructions for calculating the numerical values of various physical quantities in different regions of the Sun. Fully updated throughout, with the latest results in solar physics, this second edition covers a wide range of topics on the Sun and stellar astrophysics, including the structure of the Sun, solar radiation, the solar atmosphere, and Sun-space interactions. It explores how the physical conditions in the visible surface of the Sun are determined by the opacity of the material in the atmosphere. It also presents the empirical properties of convection in the Sun, discusses the physical conditions which must be satisfied for nuclear reactions to occur in the core, and describes how radiation transports energy from the core outwards. This text enables a practical appreciation of the physical models of solar processes. Numerical modelling problems and step-by-step instructions are featured throughout, to empower students to calculate, using their own codes, the interior structure of different parts of the Sun and the frequencies of p-modes and g-modes. They encourage a firm grasp of the numerical values of actual physical parameters as a function of radial location in the Sun. It is an ideal introduction to solar physics for advanced undergraduate and graduate students in physics and astronomy, in addition to research professionals looking to incorporate modelling into their practises. Extensive bibliographies at the end of each chapter enable the reader to explore the latest research articles in the field. Features: Fully updated with the latest results from the spacecraft Hinode, Stereo, Solar Dynamics Observatory (SDO), Interface Region Imaging Spectrograph (IRIS), and Parker Solar Probe Presents step-by-step explanations for calculating numerical models of the photosphere, convection zone, and radiative interior with exercises and simulation problems to test learning Describes the structure of polytropic spheres and the acoustic power in the Sun and the process of thermal conduction in different physical conditions
