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.

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.

Download Magnetic Coupling between the Interior and Atmosphere of the Sun Book in PDF, ePub and Kindle
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 current status of magnetic eld measurements and their implications in the light of recenttheoriesandnumericalmodelingthataddressthe fundamentalscalesandp- cessesinthehighlymagnetizedturbulentplasmawerereviewedduringthismeeting. 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. Using sophisticated image processing techniques, such telescopes r- tinelygenerateobservationswitharesolutionbetterthan0. 1arcsec,therebyyielding more informative diagnostics for instance of the microstructure of ux tubes.

Download MHD Structures, Waves and Turbulence in the Solar Wind Book in PDF, ePub and Kindle
This is the first book to give a comprehensive overview of recent observational and theoretical results on solar wind structures and fluctuations and magnetohydrodynamic waves and turbulence, preference being given to phenomena in the inner heliosphere. Emphasis is placed on the progress made in the past decade in the understanding of the nature and origin of especially small-scale, compressible and incompressible fluctuations. Turbulence models describing the spatial transport and spectral transfer of the fluctuations in the inner heliosphere are discussed. Intermittency of solar wind fluctuations and their statistical distributions are investigated. Studies of the heating and acceleration effects of the turbulence on the background wind are critically surveyed. Finally, open questions concerning the origin, nature and evolution of the fluctuations are listed, and perspectives for future research are outlined. The book is for graduate students and researchers in the field. Other target groups are scientists and professionals interested in space plasma physics and/or MHD turbulence.
