An Introduction to Waves and Oscillations in the Sun de A. Satya Narayanan

An Introduction to Waves and Oscillations in the Sun: Astronomy and Astrophysics Library

Autor A. Satya Narayanan
en Limba Engleză Paperback – 15 oct 2014
“An Introduction to Waves and Oscillations in the Sun” is intended for students and researchers who work in the area of solar and astrophysics. This book contains an introduction to the Sun, basics of electrodynamics, magneto-hydrodynamics for force-free and current-free fields. It deals with waves in uniform media with relevance to sound waves and Alfven waves, and with waves in non-uniform media like surface waves or waves in a slab and cylindrical geometry. It also touches on instabilities in fluids and observational signatures of oscillations. Finally, there is an introduction to the area of helio-seismology, which deals with the internal structure of the Sun.

Recenzii

From the reviews:
“The book … give an introductory development of the theory of wave motion and oscillations in the sun and describe the experimental and observational work that has been done. … Much of the material in this book is presented at an introductory level that would be accessible to students in an advanced undergraduate or graduate course on the subject. … The book can … be a valuable resource for scientists at any level working in this area.” (Stephen Wollman, Zentralblatt MATH, Vol. 1262, 2013)

Textul de pe ultima copertă

Astrophysicists and others studying the Sun will find this expansive coverage of what we know about waves and oscillations in our nearest star an informative introduction to a hot contemporary topic. After a section summarizing the Sun's physical characteristics, the volume moves on to explore the basics of electrodynamics, which in turn facilitate a discussion of magnetohydrodynamics (MHD). The material also details the often complex nature of waves and oscillations in uniform and non-uniform media, before categorizing the observational signatures of oscillations and exploring the instabilities in fluid, dealing with a range of known forms. Lastly, a section on helioseismology explores our growing familiarity with the internal structure of the Sun.
This book is a unified portal to a thorough grounding in solar waves that includes a wealth of explanatory vignettes demystifying concepts such as flux tubes, current-free and force-free magnetic fields, the prominences, and the relationship between the vorticity and the induction equation. It also sets out the elegant Parker solution describing the phenomenon of solar wind. The volume will inspire readers with the unbridled enthusiasm of astrophysicists who view the Sun as a giant natural plasma laboratory, in interstellar terms located right on our doorstep, in which they can apply and then verify experimental and theoretical studies on plasma through their own observation
