Download or read book The Temperature Distribution in the Solar Chromosphere written by Stuart D. Jordan and published by . This book was released on 1969 with total page 136 pages. 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.

Download or read book Basic Plasma Processes on the Sun written by E.R. Priest and published by Springer Science & Business Media. This book was released on 1990-09-30 with total page 574 pages. Available in PDF, EPUB and Kindle. Book excerpt: Much of the excitement in modern Solar Physics has come from the realisation that the Sun is a plasma and that this plasma is interacting with the magnetic field in a wide variety of subtle ways. As well as being of great interest in their own right the observed plasma phenomena on the Sun are of much wider importance, since they reveal to us details of basic phenomena that are expected to be occurring throughout the universe. It was with this in mind that 173 solar physicists from 17 countries gathered together in Bangalore with an air of anticipation. We were not disappointed as we received the warmest of welcomes from our graceful and charming host,Vinod Krishan. She and her colleagues worked tirelessly to make our stay a most memorable one and to ensure that the meeting ran with calm and efficiency. In addition to being stimulated by an excellent series of talks on the up-to-the minute advances in our subject, it was a pleasure to make new friendships from so many countries and to learn, in particular, of the Solar Physics being done in India which has a great tradition and is of a high standard. Furthermore, we enjoyed hearing about Indian culture and appreciating its beauty, especially on our day's tour into the countryside to visit some Hindu and Jain temples.

Available in PDF, EPUB and Kindle. Book excerpt: Advances in Space Science and Technology, Volume 5 looks into the major unsolved solar problems of thermodynamic structure, geometrical structure, velocity fields, flares and other transient phenomena, solar magnetic fields, and corpuscular emission. This book discusses the design, development, and testing of launching rockets. Organized into five chapters, this volume begins with an overview of the role of space observations in solar physics. This text then examines the progress in communication relay satellite techniques, which is a very important aspect of space technology. Other chapters provide a comprehensive review of solid propellant rocker technology, treating such subjects as factors affecting propellant performance, ignition, grain design, testing, quality control, and thrust vector control. This book discusses as well the characteristics of an environmental control compatible with requirements within the manned space vehicle. The final chapter deals with orbital operations. This book is a valuable resource for astronautical researchers, astronomers, and scientists.
Download or read book A Guide to the Solar Corona written by Donald E. Billings and published by Academic Press. This book was released on 2013-10-22 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Guide to the Solar Corona is specifically directed to the space scientist or engineer who is not a specialist in solar physics, but whose work requires a fairly detailed knowledge of the corona. It is hoped that the material may prove useful to most graduate students in astrophysics, while solar physicists may find some topics of interest and value to them. The book contains 12 chapters and begins with three descriptive chapters that provide the casual reader with a concept of the corona as it is evident through more or less direct observation. Topics covered include the development of coronal science, observational techniques, and observational aspects of the corona. The next chapter discusses methods of analyzing coronal data. Subsequent chapters present theoretical considerations as they are applicable to the corona. These combine theory with observation to provide a description of the various aspects of the corona. The final chapter is a combination of established ideas and speculation on the place of the corona in the universe.
Download or read book Physics of the Invisible Sun written by Ashok Ambastha and published by CRC Press. This book was released on 2020-03-27 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physics of the invisible Sun: Instrumentation, Observations, and Inferences provides a new updated perspectives of the dramatic developments in solar physics mainly after the advent of the space era. It focusses on the instrumentation exploiting the invisible windows of the electromagnetic spectrum for observing the outer, fainter layers of the Sun. It emphasizes on the several technical and observational challenges and proceeds to discuss the discoveries related to energetic phenomena occurring in the transition region and corona. The book begins with giving a brief glimpse of the historical developments during the pre-, and post-telescopic periods of visible and spectroscopic techniques, ground-based optical and radio observing sites. Various types of telescopes and back-end instrumentation are presented based on photometry, spectroscopy, and polarimetry using the Zeeman and Hanle effects for measurement of magnetic fields, and Doppler effect for radial velocity measurements. The book discusses theoretical and observational inferences based on detection of solar neutrinos, and helioseismology as the probes of the hidden solar interior, and tests of solar standard models. The characteristic properties and observational signatures of global solar p- and g-oscillations modes, developments in local helioseismology and asteroseismology are discussed. The role of the solar magnetic field and differential rotation in the activity and magnetic cycles, prediction methodologies, and dynamo models are described. Observing the Sun in IR at the longer, and the UV, EUV, XUV, X-rays, and gamma-rays at the shorter wavelengths are covered in detail. Observational challenges at each of these wavelengths are presented followed by the instrumentation for detection and imaging that have resulted in enhancing the understanding of various solar transient phenomena, such as, flares and CMEs. The outer most corona is described as a dynamic, expanding component of the Sun from the theoretical and observational perspectives of the solar wind. It then discusses the topics of the Interplanetary magnetic field, slow and fast solar wind, interaction with magnetised and non-magnetised objects of the solar system, the space weather and the physics of the heliosphere. The chapter on the future directions in solar physics presents a brief overview of the new major facilities in various observing windows, and the future possibilities of observing the Sun from ground and vantage locations in space. Features: Systematic overview of the developments in instrumentation, observational challenges and inferences derived from ground-based and space-borne solar projects. Advances in the understanding about the solar interior from neutrinos and helioseismology. Recent research results and future directions from ground- and space-based observations. This book may serve as a reference book for scientific researchers interested in multi-wavelength instrumentation and observational aspects of solar physics. It may also be used as a textbook for a graduate-level course.
