This book was released on 2012-12-06 with total page 517 pages. Available in PDF, EPUB and Kindle. Book excerpt: The widespread tendency in solar physics to divide the solar atmosphere into separate layers and to distinguish phenomena of solar activity from phenomena of the quiet Sun emphasizes the wide ranging diversity of physical conditions and events occurring in the solar atmosphere. This diversity spans the range from a neutral, essentially quiescent atmosphere to a highly ionized, violently convective atmosphere; from a domain in which magnetic field effects are unimportant to a domain in which the magnetic pressure exceeds the gas pressure, and from a domain in which the particle motions are Maxwellian to a domain in which an appreciable fraction of the particles is accelerated to relativistic energies. It is now widely recognized that the chromosphere and corona have a common origin in the mechanical energy flux generated in the hydrogen convection zone lying beneath the photosphere. Furthermore, magnetic field phenomena appear to be as vital to the structure of th~ quiet Sun as to the active Sun. For these reasons it appears desirable to present a unified treatment of the entire solar atmosphere, both active and quiet, in a single volume. On the other hand, such a treatise must be very long if it is to avoid being superficial, and it is very difficult for a single author to write authoritatively on such a wide range of topics.

Available in PDF, EPUB and Kindle. Book excerpt: A new approximate method is developed for calculating the temperature distribution in an atmosphere where local mechanical-energy dissipation is balanced by local net radiative loss in one or more spectral lines for which the atmosphere is optically thick. The method uncouples the equations of radiative transfer for the individual spectral lines from the energy-conservation equation and from each other. This permits a solution of each individual transfer equation for the radiation field in each line. These results, used in the energy-conservation equation, yield the temperature distribution if the optical depth ratio of the spectral lines at each point is known. The method is applied to selected strong resonance lines in the solar chromosphere.

Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the Summerschool and Workshop Motions in the Solar Atmosphere held from September 1st to September 12th, 1997, at the Solar Observatory Kanzelh6he, which belongs to the Astronomical Institute of the University of Graz, Austria. This type of conference has proved to be very successful in bringing together experts from specialized topics in solar physics and young scientists and students from different countries. Moreover, the summerschool was accompanied by a workshop which offered young scientists the opportunity to present their new results to a general audience. In total the summerschool and the workshop were attended by 50 par ticipants from 10 different countries. The topic selected was quite general, covering the whole solar atmo sphere and its dynamic processes: from dynamo actions and large and small scale motions in the photosphere through the complex dynamics of the chro mosphere to the corona. Also the possible influences of variations in solar output parameters to the Earth's climate were addressed. The main lec tures were given by 7 lecturers. Furthermore, there were 20 contributions to the workshop which were presented in oral form. The selection of the Kanzelh6he Solar Observatory located in Central Europe, Austria, also permitted colleagues from the former eastern coun tries to attend the meeting. At the Kanzelh6he Observatory new instru ments had been recently installed so that the meeting provided a further stimulus for the local people working there.
Download or read book New Millennium Solar Physics written by Markus J. Aschwanden and published by Springer. This book was released on 2019-05-22 with total page 714 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is a follow-on book to the introductory textbook "Physics of the Solar Corona" previously published in 2004 by the same author, which provided a systematic introduction and covered mostly scientific results from the pre-2000 era. Using a similar structure as the previous book the second volume provides a seamless continuation of numerous novel research results in solar physics that emerged in the new millennium (after 2000) from the new solar missions of RHESSI, STEREO, Hinode, CORONAS, and the Solar Dynamics Observatory (SDO) during the era of 2000-2018. The new solar space missions are characterized by unprecedented high-resolution imaging, time resolution, spectral capabilities, stereoscopy and tomography, which reveal the intricate dynamics of magneto-hydrodynamic processes in the solar corona down to scales of 100 km. The enormous amount of data streaming down from SDO in Terabytes per day requires advanced automated data processing methods. The book focuses exclusively on new research results after 2000, which are reviewed in a comprehensive manner, documented by over 3600 literature references, covering theory, observations, and numerical modeling of basic physical processes that are observed in high-temperature plasmas of the Sun and other astrophysical objects, such as plasma instabilities, coronal heating, magnetic reconnection processes, coronal mass ejections, plasma waves and oscillations, or particle acceleration.

Download or read book Solar Composition and its Evolution from Core to Corona written by Claus Fröhlich and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 438 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of chemical elements in celestial bodies and the first estimates of the chemical composition of the solar atmosphere were early results of Astrophysics - the subdiscipline of Astronomy that was originally concerned with the general laws of radiation and with spectroscopy. Following the initial quantitative abundance studies by Henry Norris Russell and by Cecilia Payne-Gaposchkin, a tremendous amount of theoretical, observa tional, laboratory and computational work led to a steadily improving body of knowledge of photospheric abundances - a body of knowledge that served to guide the theory of stellar evolution. Solar abundances determined from photospheric spectra, together with the very similar abundances determined from carbonaceous chondrites (where extensive information on isotopic composition is available as well), are nowadays the reference for all cosmic composition measures. Early astrophysical studies of the solar photospheric composition made use of atmosphere models and atomic data. Consistent abundances derived from different atmospheric layers and from lines of different strength helped to confirm and estab lish both models and atomic data, and eventually led to the now accepted, so-called "absolute" abundance values - which, for practical reasons, however, are usually given relative to the number of hydrogen nuclei.

Download or read book MHD Waves in the Solar Atmosphere written by Bernard Roberts and published by Cambridge University Press. This book was released on 2019-07-18 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume presents a full mathematical exposition of the growing field of coronal seismology which will prove invaluable for graduate students and researchers alike. Roberts' detailed and original research draws upon the principles of fluid mechanics and electromagnetism, as well as observations from the TRACE and SDO spacecraft and key results in solar wave theory. The unique challenges posed by the extreme conditions of the Sun's atmosphere, which often frustrate attempts to develop a comprehensive theory, are tackled with rigour and precision; complex models of sunspots, coronal loops and prominences are presented, based on a magnetohydrodynamic (MHD) view of the solar atmosphere, and making use of Faraday's concept of magnetic flux tubes to analyse oscillatory phenomena. The rapid rate of progress in coronal seismology makes this essential reading for those hoping to gain a deeper understanding of the field.
