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.
Download or read book Magnetic Reconnection written by Eric Priest and published by Cambridge University Press. This book was released on 2007-02-15 with total page 616 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic reconnection is at the core of many dynamic phenomena in the universe, such as solar flares, geomagnetic substorms and tokamak disruptions. Written by two world leaders on the subject, this volume provides a comprehensive overview of this fundamental process. Coverage gives both a pedagogical account of the basic theory and a wide-ranging review of the physical phenomena created by reconnection--from laboratory machines, the Earth's magnetosphere, and the Sun's atmosphere to flare stars and astrophysical accretion disks. It also includes a succinct account of particle acceleration by electric fields, stochastic fields and shock waves, and how reconnection can be important in these mechanisms. Clearly written and highly accessible, this volume serves as an essential introduction for graduate students in solar physics, astrophysics, plasma physics and space science. Researchers in these fields also will find Magnetic Reconnection an authoritative reference.
Download or read book Solar Prominences written by Jean-Claude Vial and published by Springer. This book was released on 2014-11-24 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents the latest research results on solar prominences, including new developments on e.g. chirality, fine structure, magnetism, diagnostic tools and relevant solar plasma physics. In 1875 solar prominences, as seen out of the solar limb, were described by P.A. Secchi in his book Le Soleil as "gigantic pink or peach-flower coloured flames". The development of spectroscopy, coronagraphy and polarimetry brought tremendous observational advances in the twentieth century. The authors present and discuss exciting new challenges (resulting from observations made by space and ground-based telescopes in the 1990s and the first decade of the 21st century) concerning the diagnostics of prominences, their formation, their life time and their eruption along with their impact in the heliosphere (including the Earth). The book starts with a general introduction of the prominence “object” with some historical background on observations and instrumentation. In the next chapter, the various forms of prominences are described with a thorough attempt of classification. Their thermodynamic (and velocity) properties are then derived with emphasis on the methods (and their limits) used. This goes from the simplest optically thin case to the heavy radiative treatment of plasmas out of local thermodynamic equilibrium. The following chapters are devoted to the magnetic field measurements and indirect derivation. A new branch of diagnostic tools, the seismology, is presented along with some MHD basics. This allows to better understand the propagation of waves, the energy and force equilibria. Both small-scale and large-scale studies and their relationship are presented. The importance of the newly discovered cavities is stressed in the context of prominence destabilization. The issues of prominence formation and eruption, their connection with flares and Coronal Mass Ejections and their impact on the Earth are addressed on the basis of the latest results. Finally, an exciting new area of research is unveiled with the newly discovered evidence of similar manifestations in the Universe and their possible impact on the habitability of exoplanets. References to the basic physics (where necessary) are provided and the proposed web sites addresses will allow the reader to load exciting movies. The book is aimed at advanced students in astrophysics, post-graduates, solar physicists and more generally astrophysicists. Amateurs will enjoy the many new images which go with the text.

Download or read book Nature of Prominences and their Role in Space Weather IAU S300 written by Brigitte Schmieder and published by Cambridge University Press. This book was released on 2014-02-13 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar prominences and filaments are large gaseous features extending outward hundreds of thousands of kilometres from the Sun's surface, which play an active role in space weather. Magnetic clouds and interplanetary coronal mass ejections associated with erupting prominences can produce severe perturbations in the Earth's near-space environment. IAU Symposium 300 presents a review of the state-of-the-art theoretical and numerical modelling of prominences and filaments, and their role in the dynamics of Sun-Earth relations. Observations from the latest international space-borne missions (Hinode, STEREO and SDO) and ground-based observatories are presented. The Symposium benefits not just newcomers to solar physics research but it shares the current status of our sophisticated solar analysis with the stellar community, now that huge prominences and CMEs have been detected in solar-type stars, and others, which will affect any exoplanets they host.
Download or read book Solar and Interplanetary Dynamics written by M. Dryer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Informal discussions in 1977 among a number of scientists asso ciated with solar and interplanetary physics revealed a need for a dialogue between the two often-divergent groups. It was clear that the latter group was dependent essentially on the sun for its raison d'etre. On the other hand it was also clear that the former group could benefit in its search for insight vis-a-vis solar activity by looking beyond the shell of the inner corona. Needless to add that the combined solar/interplanetary topic is relevant to astrophysics when one considers stellar winds and binary star flows. It was felt, there fore, that a symposium was essential to bring together, for the first time, leading solar and interplanetary physicists from the interna tional community to discuss and record herein their own research. The fundamental physical processes underlying our own capricious star's activity can be understood only by the coupling of solar and interplan etary topics in an intimate observational and theoretical structure. This book, intended for active research scientists and advanced grad uate students, is an important step in this direction. The background of solar and interplanetary dynamics is provided in Part I (The Life History of Coronal Structures and Fields) and Part II (Coronal and Interplanetary Responses to Long Time Scale Phenomena).
Download or read book Emergence of Twisted Magnetic Flux Into the Corona written by and published by . This book was released on 2005 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall goal of this proposal has been to describe the emergence, evolution, and eruption of magnetic flux ropes in the %corona. The following achievements are noted: 1. A numerical model of magnetic flux emergence (Fan and Gibson, 2003;2004,' Fan, 2005), demonstrating both flux rope equilibria and instabilities leading to eruptions. 2. A numerical model of dynamic magnetic flux emergence (Manchester et at., 2004; Fan, 2004). 3. A comparison of model predictions to CME precursor observations, including X-ray sigmoids and associated filaments, and rotating sunspots (Gibson et at., 2004; 2005a), and a comprehensive observational analysis of white light cavities in quiescent streamers (Gibson et at., 2005b). 4. An analytic flux rope model (Gibson et at., 2002) allowing parameterized studies of magnetic free energy 5. Tests of standard observational analysis techniques such as helicity injection (Gibson et at., 2004), inference of magnetic twist (Leka et at., 2005), and coronal field extrapolations (Barnes et at., 2005a; 2005b). 6. A comparison of equilibrium states, eruptive properties and observables for 3D vs. 2D models (Fan and Gibson, 2005) 7. A comparison of flux rope simulations with sigmoid evolution, including the demonstration of partially erupting flux ropes.
Download or read book Solar Surface Magnetism written by R. J. Rutten and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 532 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observations of the solar magnetic field are largely confined to the radiation emitted from the photosphere, the thin layer of the solar atmosphere which we call "the solar surface". It is from solar surface observations that we must infer the internal structure and the internal magnetohydrodynamic processes that lead to the multitude of fascinat ing phenomena of solar magnetic activity, and from solar surface observations we must also infer the interplay of convection and magnetism that regulates field dispersal, drives the heating of the outer-atmospheric plasma, and generates the solar wind. There is much to be learned from solar surface magnetism in physics and astrophysics; currently, there are rapid developments in this exciting field. The workshop of which this volume contains the proceedings aimed at a synthesis between observers and theorists, both with regard to the discrete elements that are the building blocks of solar magnetism and with regard to the larger-scale spatial and temporal patterns in which the magnetic elements emerge and disappear. The workshop was held during November 1-5, 1993 in Soesterberg, The Netherlands. The fifty participants took a very active part in making the workshop quite a lively one. The articles in these proceedings cover most of the oral and poster presentations, excepting a dozen soon to be published elsewhere.

Download or read book Dynamic Coronal Mass Ejection Processes and Magnetic Reconnection written by Alshaimaa Saad Hassanin and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sun is the nearest star to the Earth. It consists of an interior and an atmosphere. The convection zone is the outermost layer of the solar interior. A flux rope may emerge as a coherent structure from the convection zone into the solar atmosphere or be formed by magnetic reconnection in the atmosphere. A flux rope is a bundle of magnetic field lines twisting around an axis field line, creating a helical shape by which dense filament material can be supported against gravity. The flux rope is also considered as the key structure of the most energetic phenomena in the solar system, such as coronal mass ejections (CMEs) and flares. These magnetic flux ropes can produce severe geomagnetic storms. In particular, to improve the ability to forecast space weather, it is important to enrich our knowledge about the dynamic formation of flux ropes and the underlying physical mechanisms that initiate their eruption, such as a CME. A confined eruption consists of a filament eruption and usually an associated are, but does not evolve into a...
