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.

Download or read book Multiscale Coupling of Sun Earth Processes written by A.T.Y. Lui and published by Elsevier. This book was released on 2005-07-06 with total page 527 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many approaches exist for scientific investigations and space research is no exception. The early approach during which each space plasma region within the Sun-Earth system was investigated separately with physics-based tools has now progressed to encompass investigations on coupling between these regions. Ample evidence now exists indicating the dynamic processes in these regions exhibit disturbances over a wide range of scales both in time and space. This new reckoning naturally leads to an emerging perspective of probing these natural phenomena with concepts and tools developed in modern statistical mechanics for physical processes governing the evolution of out-of-equilibrium and complex systems. These new developments have prompted a topical conference on Sun-Earth connection, held on February 9-13, 2004 at Kailua-Kona, Hawaii, USA, with the goal of promoting interactions among scientists practicing the traditional physics-based approach and those utilizing modern statistical techniques. This monograph is a product of this conference, a compilation of thirty-nine articles assembled into seven chapters: (1) multiscale features in complexity dynamics, (2) space storms, (3) magnetospheric substorms, (4) turbulence and magnetic reconnection, (5) modeling and coupling of space phenomena, (6) techniques for multiscale space plasma problems, and (7) present and future multiscale space missions. These articles show a diversity of space phenomena exhibiting scale free characteristics, intermittency, and non-Gaussian distributions of probability density function of fluctuations in the physical parameters of the Sun-Earth system. The scope covers the latest observations, theories, simulations, and techniques on the multiscale nature of Sun-Earth phenomena and underscores the usefulness in cross-disciplinary exchange needed to unravel the underlying physical processes, which may eventually lead to a possible unified description and prediction for space disturbances. * Extensive collection of state-of-the-art papers on multiscale coupling of Sun-Earth Processes * Present and future multiscale space missions * New techniques and models for performing multiscale analysis

Download or read book Low Frequency Waves in Space Plasmas written by Andreas Keiling and published by John Wiley & Sons. This book was released on 2016-04-04 with total page 524 pages. Available in PDF, EPUB and Kindle. Book excerpt: Low-frequency waves in space plasmas have been studied for several decades, and our knowledge gain has been incremental with several paradigm-changing leaps forward. In our solar system, such waves occur in the ionospheres and magnetospheres of planets, and around our Moon. They occur in the solar wind, and more recently, they have been confirmed in the Sun’s atmosphere as well. The goal of wave research is to understand their generation, their propagation, and their interaction with the surrounding plasma. Low-frequency Waves in Space Plasmas presents a concise and authoritative up-to-date look on where wave research stands: What have we learned in the last decade? What are unanswered questions? While in the past waves in different astrophysical plasmas have been largely treated in separate books, the unique feature of this monograph is that it covers waves in many plasma regions, including: Waves in geospace, including ionosphere and magnetosphere Waves in planetary magnetospheres Waves at the Moon Waves in the solar wind Waves in the solar atmosphere Because of the breadth of topics covered, this volume should appeal to a broad community of space scientists and students, and it should also be of interest to astronomers/astrophysicists who are studying space plasmas beyond our Solar System.

This book was released on 2010-03-10 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar physics in India has a tradition that can be traced to the setting up of the Kodaikanal Observatory in 1899 when the Madras Observatory was relocated to a high altitude site with a view to initiate observations of the sun. This conference on Magnetic Coupling between the Interior and the Atmosphere of the Sun during 2–5 December 2008 was planned to coincide with centenary of the Evershed effect discovery at Kodaikanal in 1909. The aim of this meeting was to bring to a critical focus a comprehensive - derstanding of the important issues pertaining to solar magnetism with particular emphasis on the various MHD processes that operate in the solar atmosphere.

The meeting was timely for the following reasons: Space observations such as from SOHO and TRACE have provided a wealth of multiwavelength observations onprocessesoccurringinregionsofthe atmosphereextendingfromthe photosphere up to the outer corona. With the launch of Hinode and STEREO in 2006 and of SDO (Solar Dynamics Observatory) shortly, this conference provided a platform for in-depth discussions on new results from various space missions as well as a comparison with ground-based observing facilities such as the Swedish 1-m Solar Telescope.

This book was released on 2020-01-07 with total page 346 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a systematic introduction to the observation and application of kinetic Alfven waves (KAWs) in various plasma environments, with a special focus on the solar-terrestrial coupling system. Alfven waves are low-frequency and long-wavelength fluctuations that pervade laboratory, space and cosmic plasmas. KAWs are dispersive Alfven waves with a short wavelength comparable to particle kinematic scales and hence can play important roles in the energization and transport of plasma particles, the formation of fine magneto-plasma structures, and the dissipation of turbulent Alfven waves. Since the 1990s, experimental studies on KAWs in laboratory and space plasmas have significantly advanced our understanding of KAWs, making them an increasingly interesting subject. Without a doubt, the solar–terrestrial coupling system provides us with a unique natural laboratory for the comprehensive study of KAWs. This book presents extensive observations of KAWs in solar and heliospheric plasmas, as well as numerous applications of KAWs in the solar-terrestrial coupling system, including solar atmosphere heating, solarwind turbulence, solar wind-magnetosphere interactions, and magnetosphere-ionosphere coupling. In addition, for the sake of consistency, the book includes the basic theories and physical properties of KAWs, as well as their experimental demonstrations in laboratory plasmas. In closing, it discusses possible applications of KAWs to other astrophysical plasmas. Accordingly, the book covers all the major aspects of KAWs in a coherent manner that will appeal to advanced graduate students and researchers whose work involves laboratory, space and astrophysical plasmas.
