Available in PDF, EPUB and Kindle. Book excerpt: Most stars show some degree of magnetic activity, from the familiar variations in the Sun's magnetic field, which coincide with the sun-spot cycle, to the enormous magnetic fields created by rotating neutron stars. Magnetic fields are also a potential key to understanding the formation of new stars and the behavior of galactic nuclei. This book by one of the leading figures in stellar magnetism provides an authoritative survey of this rapidly developing field. Based on a lifetime of research, the book places stellar magnetism in a broad astronomical scope and provides a thorough, well-argued treatment of current work. It covers the key topics, discussing the relevant mathematics in detail and including numerous references, and many of the topics, particularly accretion discs, dynamos, and winds, are equally important to the study of galaxies and galactic nuclei.

Download or read book Solar Magnetic Fields written by Jan Olof Stenflo and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic fields are responsible for much of the variability and structuring in the universe, but only on the Sun can the basic magnetic field related processes be explored in detail. While several excellent textbooks have established a diagnostic foundation for exploring the physics of unmagnetized stellar atmospheres through spectral analysis, no corresponding treatise for magnetized stellar atmospheres has been available. The present monograph fills this gap. The theoretical foundation for the diagnostics of stellar magnetism is developed from first principles in a comprehensive way, both within the frameworks of classical physics and quantum field theory, together with a presentation of the various solar applications. This textbook can serve as an introduction to solar and stellar magnetism for astronomers and physicists at the graduate or advanced undergraduate level and will also become a resource book for more senior scientists with a general interest in cosmic magnetic fields.
Download or read book Solar and Stellar Dynamos written by Paul Charbonneau and published by Springer. This book was released on 2012-11-06 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astrophysical dynamos are at the heart of cosmic magnetic fields of a wide range of scales, from planets and stars to entire galaxies. This book presents a thorough, step-by-step introduction to solar and stellar dynamos. Looking first at the ultimate origin of cosmic seed magnetic fields, the antagonists of field amplification are next considered: resistive decay, flux expulsion, and flows ruled out by anti-dynamo theorems. Two kinematic flows that can act as dynamos are then studied: the Roberts cell and the CP-flow. Mean-field electrodynamics and derivation of the mean-field dynamo equations lead to the alpha Omega-dynamo, the flux transport dynamo, and dynamos based on the Babcock-Leighton mechanism. Alternatives to the mean-field theory are also presented, as are global MHD dynamo simulations. Fluctuations and grand minima in the solar cycle are discussed in terms of dynamo modulations through stochastic forcing and nonlinear effects. The book concludes with an overview of the major challenges in understanding stellar magnetic fields and their evolution in terms of various dynamo models, global MHD simulations, and fossil fields. Each chapter is accompanied by an annotated bibliography, guiding the readers to the relevant technical literature, which may lead them to carry out their own research in the field of dynamo theory.

Download or read book Cosmic Magnetic Fields written by Jorge Sánchez Almeida and published by Cambridge University Press. This book was released on 2018-04-12 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic fields pervade the universe and play an important role in many astrophysical processes. However, they require specialised observational tools, and are challenging to model and understand. This volume provides a unified view of magnetic fields across astrophysical and cosmological contexts, drawing together disparate topics that are rarely covered together. Written by the lecturers of the XXV Canary Islands Winter School, it offers a self-contained introduction to cosmic magnetic fields on a range of scales. The connections between the behaviours of magnetic fields in these varying contexts are particularly emphasised, from the relatively small and close ranges of the Sun, planets and stars, to galaxies and clusters of galaxies, as well as on cosmological scales. Aimed at young researchers and graduate students, this up-to-date review uniquely brings together a subject often tackled by disconnected communities, conveying the latest advances as well as highlighting the limits of our current understanding.

This book was released on 2014-08-28 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: All phases of stellar evolution are influenced by the presence of magnetic fields in the star's interior and close environment. IAU Symposium 302 gives an overview of the emerging field of stellar magnetism. The last few years have seen the dawn of a new era in this research domain, with the advent of powerful tools strengthening both observational and modelling approaches, rapidly changing our view of the role stellar magnetism plays throughout stellar evolution. The topics covered span all phases of evolution, from the formation of stars and their early accreting years, through main sequence evolution for both low and high mass stars, and also the final stages of stellar evolution. This volume features the most recent advances achieved by major observatories (ground-based and space-borne) and through massively-parallel 3D numerical simulations, benefiting astronomers interested in the latest observational and theoretical developments in this exciting and growing field.
Download or read book Magnetic Fields of Celestial Bodies written by Ye Shi-hui and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 349 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetism is one of the basic properties of matter. Mankind has trav elled a long road in discovering and utilizing magnetism, and in this respect the ancient Chinese people have made outstanding contribu tions. In the book 'Lu's Spring and Autumn', written near the end of the Warring States Period, i. e. in the third century B. C. , there is a statement on the "attraction of iron by lodestones". So at that time it was known that magnets can attract ferromagnetic material. At the be ginning ofthe first century A. D. , viz. in the early years ofthe East Hang Dynasty, the famous scholar Wang Chong wrote in his masterpiece 'Len Hen' that the handle of a magnetic dipper pointed to the south. It was thus discovered at the time that magnets can point to the poles of the geomagnetic field. At the beginning of the twelfth century, during the reign of Emperor Hui of the Sung Dynasty, in the two books written by Zhu Yo and Xu Jin, respectively, there are descriptions of the com pass used in navigation. This tells us that the application of compasses was rather widespread at that time. The distinguished scientist Sen Go (1031-1085) discovered the declination of the terrestrial magnetic field. This is four hundred and more years earlier than its discovery by Christopher Columbus in 1492 during his voyage across the Atlantic Ocean. Such facts as these manifest the important contributions of ancient China to global civilization.

Download or read book Solar and Stellar Magnetic Activity written by C. J. Schrijver and published by Cambridge University Press. This book was released on 2008-10-30 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This timely volume provides the first comprehensive review and synthesis of current understanding of magnetic fields in the Sun and similar stars. Magnetic activity results in a wealth of phenomena - including starspots, non-radiatively heated outer atmospheres, activity cycles, deceleration of rotation rates, and even, in close binaries, stellar cannibalism - all of which are covered clearly and authoritatively. This book brings together for the first time recent results in solar studies and stellar studies. The result is an illuminating new view of stellar magnetic activity. Key topics include radiative transfer, convective simulations, dynamo theory, outer-atmospheric heating, stellar winds and angular momentum loss. Researchers are provided with a state-of-the-art review of this exciting field, and the pedagogical style and introductory material make the book an ideal and welcome introduction for graduate students.

This book was released on 2012-12-06 with total page 476 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented at IAU Colloquium No. 90. at the Crimean Astrophysical Observatory in May of 1985. A few additional contributions are included from authors who for various reasons were unable to attend the meeting. Four years have passed since the last major international conference on chemically peculiar stars of the upper main sequence was held in Liege. Belgium in 1981. Previous conferences were held in 1975 (Vienna. Austria) and in 1965 (Greenbelt. Maryland. USA). As the proceedings of this Colloquium show. the recent availability of ultraviolet spectra of large numbers of normal and chemically peculiar A and B stars is having a major impact on the way we study these objects. and has led to many new. exciting and unanticipated results. Simultaneously. the more traditional study of optical spectra has been advanced through the increasing use of very high spectral resolution with high signal-to-noise detectors. The chemically peculiar (CP) stars on the upper main sequence belong in the standard framework within which we understand stellar evolution and the history of matter. Recent work has made it clear that the unusual chemistry and magnetic structure of these objects is of relevance across the broad domain of stellar astronomy. from the upper main sequence to horizontal branch stars and white dwarfs. Metal poor (J>. Boo) as well as metal rich (Ap. Am) stars are an integral part of the picture.

This book was released on 2020-10-31 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent observational results from space- and ground-based telescopes have demonstrated that a unified approach to the relationships between solar and stellar magnetism is necessary to advance our understanding of magnetic fields. The Proceedings of IAU Symposium 354 present recent results and discussions of emerging topics, including: magnetic field diagnostics using high-resolution observation; initial data from ALMA, Chinese Radio Spectroheliograph and other instruments; the detection of stellar magnetospheres; and the detailed mapping of magnetic fields on the surface of stars using new unique instrumentation. These observations stimulate comparisons of solar and stellar results, and improve our understanding of how surface magnetic structures and their evolution are related to the generation of magnetic fields by dynamos in solar and stellar interiors. This volume benefits graduate students and researchers interested in the recent advances and key problems of solar and stellar magnetic fields, and their impacts on planetary atmospheres.
