Download or read book Fragmented Energy Release in Sun and Stars written by G.H.J. van den Oord and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 380 pages. Available in PDF, EPUB and Kindle. Book excerpt: Magnetic energy release plays an important role in a wide variety of cosmic objects such as the Sun, stellar coronae, stellar and galactic accretion disks and pulsars. The observed radio, X-ray and gamma-ray emission often directly results from magnetic `flares', implying that these processes are spatially fragmented and of an impulsive nature. A true understanding of these processes requires a combined magnetohydrodynamical and plasma physical approach. Fragmented Energy Release in Sun and Stars: the Interface between MHD and Plasma Physics provides a comprehensive, interdisciplinary summary of magnetic energy release in the Sun and stars, in accretion disks, in pulsar magnetospheres and in laboratory plasmas. These proceedings include papers on both theoretical and observational aspects. Fragmented Energy Release in Sun and Stars: the Interface between MHD and Plasma Physics is for researchers in the fields of solar physics, stellar astrophysics and (laboratory) plasma physics and is a useful resource book for graduate level astrophysics courses.

Available in PDF, EPUB and Kindle. Book excerpt: From the dawn of human civilisations, Sun has played a crucial role in the wonderland of the human mind. It has been perceived as a powerful deity in the mythology of many civilisations because of its role in providing the life on Earth. Today, we know that it is an ordinary star, which is centred at our solar system. It bears more than 99% mass of the solar system and holds all the planets in the solar system together by its gravity. The Sun has formed 4.5 billion years ago from the collapse of a giant, rotating cloud of gas and dust, called the solar nebula. It is a Population I star that is rich in heavy elements, and formed from the remnants of the supernova explosion of a previous giant star. It is primarily composed of hydrogen (73%) and helium (25%) with a negligible amount of heavier elements such as oxygen, carbon, neon, silicon, magnesium and iron. The Sun is a main-sequence star with a spectral class of G2V. It is located at a distance of 1.496× 108 km (1 AU) from the Earth and has a radius of 696,342 ± 65 km, which is about 109 times the radius of the Earth. The mass of Sun is 1.9885 × 1030 kg, and its luminosity is 3.86 × 1026 W. The solar spectrum can be approximated by blackbody radiation with a temperature of 5785 K, that corresponds to the effective surface temperature of the Sun . The study of the Sun can be divided into two parts. The solar interior that is composed of the core, the radiative zone and the convective zone, and the solar atmosphere that includes the photosphere, the chromosphere, the transition region and the corona. Solar interior is primarily divided into three main regions based on energy generation and transfer processes. They are - the core, the radiative & the convective zone.

Available in PDF, EPUB and Kindle. Book excerpt: Infrared Solar Physics contains the proceedings of the 154th Symposium of the International Astronomical Union held in Tucson, Arizona, March 2--5, 1992. Aimed at active workers and graduate students in solar physics, this volume provides the first comprehensive view of a rapidly expanding discipline that gives us a new perspective on the sun. Measurements across the wide infrared spectral range -- here, from 1 mum to 1 mm -- can probe the solar atmosphere from below the visible surface through the outer reaches of the corona. Taking full advantage of revolutionary advances in detector technology, infrared observations from the ground, aircraft and space have led to a better understanding of solar magnetic fields, atmospheric structure and activity, and elemental abundances. The infrared has also provided new interpretive challenges, such as the appearance of the 12-mum emission lines of magnesium. These and other developments are discussed here by the leading contributors to the field, who also give their perspectives on the future of this rich field of study.
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.

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 Heliospheric Plasma Physics written by George M. Simnett and published by Springer. This book was released on 1997-06-19 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume brings together theoretical ideas on the plasma physics of both hot and dense plasmas in the solar atmosphere and similar physics applied to the tenuous and cooler plasmas found in the heliosphere. It is complemented by recent observations. Helioseismology covers the solar interior and the neutrino problem. Solar and stellar activity cycles are addressed. The dynamics of magnetic flux tubes in the solar atmosphere and material flows through the chromosphere into the upper atmosphere are comprehensively reviewed. Energy release processes and the production of energetic particles are important to understanding events in the solar atmosphere and to the dynamics of the tenuous heliosphere. A glimpse of the future is offered by concluding chapters on new ground-based and space instrumentation.
Download or read book Solar System Plasmas in Space and Time written by J. L. Burch and published by American Geophysical Union. This book was released on 1994-01-10 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 84. Solar system plasmas are highly structured and dynamic and are characterized by great variability in both space and time. The variations in their spatial distribution and temporal evolution occur on a variety of scales, ranging from kilometers (ion gyroradius) to hundreds of thousands of kilometers (coronal mass ejections) and from microseconds (electron plasma frequency) to years (solar sunspot cycle). Space plasma physicists seeking to understand the complex plasma phenomena that occur at the Sun, in the solar wind, and in the magnetospheres and ionospheres of the Earth and other solar system bodies thus face twin challenges. First, they must distinguish variations that are spatial in nature from those that are temporal. The heavy reliance in past investigations on singlepoint in situ measurements has significantly limited their ability to do this. Second, space physicists must elucidate the interrelationships among micro-, meso-, and macroscale plasma phenomena, relationships that organize the various solar system plasmas into a single heliospheric plasma system embedded in the interstellar medium. Here, too, experimental limitations have constrained the development of a global picture of solar system plasmas. However, new technologies promise a significant advance in our understanding of the interconnectedness of solar system plasmas.
