Available in PDF, EPUB and Kindle. Book excerpt: Magnetic fields are ubiquitous in the universe and their study forms an important area of research in modern day astrophysics. Starting from planetary magnetic fields like the one of the Earth, magnetic fields are found to exist in stars like the Sun, in galaxies to clusters of galaxies. The importance of magnetic fields for our understanding of the Universe has been appreciated since mid-1950's when the advent of radio astronomy and the studies of cosmic ray propagation and confinement revealed a Universe filled with thermal and relativistic plasma whose motions are controlled by magnetic fields. Indeed, cosmic magnetic fields play a crucial role in a number of physical processes in the universe from confining cosmic rays, controlling star formation, driving turbulence in accretion discs, to the production and collimation of jets in AGN's. An extensive review of astrophysical magnetic fields incorporating recent results are in Brandenburg and Subramanian(2005a). Let us first have a quick look into the estimates of the strength and coherence scales of magnetic fields in some astrophysical objects. The magnetic field of the Sun consists of large-scale and small-scale components. The magnetic field of the Sun consists of large-scale and small-scale components. The typical length scale associated with the large-scale field is the width of the toroidal flux belts with the same polarity around the 30° latitude corresponding to about 300 Mm (1Mm = 1000 km). The pressure scale height at the bottom of the convection zone is about 50 Mm and scales smaller than this is associated with the small-scale field.

Download or read book Cosmic Magnetism written by Percy Seymour and published by CRC Press. This book was released on 1986 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of extraterrestrial magnetic fields is a relatively new one, confirmation of the existance of the first such field (that of our Sun) having come a s late as 1908. In the past 30 years a great ammount of knowledge has been accumulated on Cosmic Magnetism, which has turned out to be a truly fascinating topic for study. Percy Seymour's book is the first to deal with the topic in a non-mathematical way, and he offers a fine introduction to his subject. The first three chapters consolidate our knowledge on magnetism in general and the magnetic field of the Earth, as well as discussing the reasons for studying astronomy and cosmic magnetism in particular. The remainder of the book is devoted to the main areas of cosmic magnetism - solar, plantetary and interplanetary fields, fields in stars and pulsars, fields of the milky way and fields in other galaxies. Cosmic Magnetism in an ideal book for sixth-formers and undergraduates studying physics or astronomy and will also appeal to amateur astronomers. as previous work on this topic has been 'hidden' in specialised academic journals.

Book excerpt: 'This book presents a clear, highly readable view of science's best understanding of how things in the Universe came to be the way they are. Each chapter is written by a leading expert in that sub-field. Together they cover nearly all major advances made in the past century, in fields from cosmology to exobiology.'Joseph H Taylor Jr.Nobel Laureate in Physics, 1993'An exhilarating tour of the Universe from true experts. For those who thirst to know how we know what we know about our place in the Universe, reading this book will be a richly rewarding experience.'Adam G RiessNobel Laureate in Physics, 2011'These are fascinating essays about the nature of the world around us by people who write well and understand what they are writing about.'P James E PeeblesNobel Laureate in Physics, 2019The book provides a broad overview of what we currently know about the Origin and Evolution of the Universe. The goal is to be scientifically comprehensive but concise. We trace the origins from the Big Bang and cosmic expansion, to the formation of galaxies, heavy elements, stars and planets as abodes for life. This field has made stunning progress since the first edition of this book. At that time, there were no known planets outside of our own Solar System (compared with the many thousands currently being studied). The origin of massive black holes was pure speculation (compared with the very recent detection of the first gravitational waves from space, produced by the cataclysmic merger of two surprisingly large black holes). And the most important energy in the Universe, now known as the Dark Energy which is accelerating the expansion, had not been discovered. We aim to bring lay readers with an interest in science 'up to speed' on all of these key discoveries that are part of the panorama of cosmic evolution, which has ultimately lead to our existence on Earth.Related Link(s)

Available in PDF, EPUB and Kindle. Book excerpt: In the last decades, palaeomagnetic research has provided important information about the past variation of the Earth’s magnetic field (EMF) from its origin to the present day. However, questions regarding the origin and evolution of the EMF as well as the frequency and spatial distribution of its variations still remain open to debate. This Special Publication provides new insights into the study of the temporal and spatial evolution of the EMF presenting new data from palaeomagnetic and rock magnetic studies of archaeological materials, sediments and lavas. The papers presented cover a wide range of topics related to archaeology, stratigraphy and climate, including new data from several parts of the world, such as Europe, Africa, Australia, New Zealand, India and the Baltic Sea. This Special Publication aims to present an overview of the most recent secular variation studies and their use to disclose fundamental properties of the EMF evolution.
Download or read book Magnetic Fields of Galaxies written by A.A. Ruzmaikin and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetism, when extended beyond normal frameworks into cosmic space is characterized by an enormous spatial scale. Because of their large sizes the nature of magnets such as the Earth and the Sun is entirely different from the nature of a horseshoe magnet. The source of cosmic magnetism is associated with the hydrodynamic motions of a highly conductive medium. In this aspect, cosmic magnets resemble a dynamo. However, currents in the dynamo flow along properly ordered wires, while chaotic, turbulent motions are dominant inside stars and liquid planetary cores. This makes more intriguing and surprising the fact that these motions maintain a regular magnetic field. Maintenance of magnetic fields is even more impressive in huge magnets, i.e. galaxies. In fact, we are living inside a giant dynamo machine, the Milky Way galaxy. Although the idea of the global magnetic field of our Galaxy was clearly proposed almost 40 years ago, firm observational evidence and definite theoretical concepts of galactic magnetism have been developed only in the last decade. This book is the first attempt at a full and consistent presentation of this problem. We discuss both theoretical views on the origin of galactic magnetism and the methods of observational study. Previous discussions were on the level of review articles or separate chapters in monographs devoted to cosmic magnetic fields (see, e.g., H. K. Moffatt, 1978, E. N. Parker, 1979 and Zeldovich et aI., 1983).
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 205 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.
