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 2014 with total page 252 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electromagnetic ion cyclotron (EMIC) waves are generated by a fundamental plasma instability and interact with multiple particle populations in the Earth's magnetosphere. This dissertation describes the application of spacecraft data and linear theory of electromagnetic waves to investigating the evolution of EMIC wave properties in the presence of multiple magnetospheric ion species. In particular, the role of the low-energy heavy ion species on the wave properties is explored. A case study describes spacecraft measurements of EMIC wave activity, the multiple ion species (hot protons, cold protons, and cold He) present during the wave activity, and the methods for performing thorough characterization and analysis of the wave observations. I show that the observed wave characteristics are not typical of such waves as established from linear cold plasma theory. By using the full range of the observations and applying them to modeling of linear wave growth, I then show that wave properties evolve in the presence of sufficient free energy (low density hot protons), high density cold protons, and warm He (~10 eV). Parametric study of linear wave growth using the observed multiple ion properties as a reference point implies that EMIC waves evolve due to these warm plasma effects of the heavier ion species, and may also evolve due to non-local generation and propagation. This motivates a global multi-spacecraft magnetospheric study of the dominant cold/warm ions (H, He+, and O+) to establish their typical properties (composition, densities, and temperatures) at different magnetospheric locations and to determine where such cold/warm ions can lead to similar evolution of warm plasma EMIC waves assuming the hot proton free energy is available. I then apply these results to successfully explain typical growth rates and properties of EMIC waves observed in each MLT sector. The results show how our findings on cold/warm ion properties can be used in future studies of EMIC wave generation and properties, including the effect of the waves on scattering of relativistic radiation belt electrons, cold ion heating, and hot ion precipitation to the ionosphere resulting in the proton aurora.

Download or read book Cyclotron Waves in Plasma written by D. G. Lominadze and published by Elsevier. This book was released on 2013-10-22 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cyclotron Waves in Plasma is a four-chapter text that covers the basic physical concepts of the theory of cyclotron waves and cyclotron instabilities, brought about by the existence of steady or alternating plasma currents flowing perpendicular to the magnetic field. This book considers first a wide range of questions associated with the linear theory of cyclotron oscillations in equilibrium plasmas and in electron plasmas in metals and semiconductors. The next chapter deals with the parametric excitation of electron cyclotron oscillations in plasma in an alternating electric field. A chapter focuses on plasma turbulence, which results from the development of cyclotron instabilities. The last chapter discusses pertinent experimental data concerning cyclotron waves in plasma. The book is intended for specialists in plasma physics and a number of related fields, including the physics of the ionosphere, solar wind and, metals, as well as for students and teachers who are specializing in these subjects.
Download or read book Testing the Theory of Radiation Belt Electron Loss by Hiss and Electromagnetic Ion Cyclotron Waves written by Ling Zheng and published by . This book was released on 2019 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hiss, chorus and electromagnetic ion cyclotron waves (EMIC wave) are three major wave modes that are widely investigated and included in the radiation belt electron models to explain electron precipitation. The quasi-linear theories of electron loss through pitch angle diffusion by hiss and EMIC waves were proposed in 1970s. Since then the testing of the theories is still going on though some progresses had been made. Comparison of theoretical predictions to electrons distribution at loss cone is one effective way to evaluate the theories. The main obstruction of loss cone testing was from the lack of measurements of the electron loss cone distribution with enough pitch angle and energy resolution and simultaneous wave activities at the heart of radiation belt. This thesis is devoted to testing the hiss and EMIC waves diffusion theories from the perspective of the electron loss cone distribution by utilizing the previously unnoticed overlap of UARS and CRRES missions in 1991. The conclusions are as following: (1) Two cases showing the consistency between quasi-linear theory of hiss diffusion and observed loss cone distribution are found. (2) In 25 out of 38 cases, hiss wave power is far insufficient in precipitating the large amount of electrons observed. Loss mechanisms other than hiss, chorus and EMIC waves are needed to account for the discrepancy. (3) Three EMIC wave events were investigated. In the first case, the isotropic distribution (sign of strong diffusion) is caused by process other than EMIC wave diffusion demonstrating that simultaneous presence of EMIC wave and electron precipitation does not guarantee any connection between the two. Large discrepancy between quasi-linear theory of EMIC wave diffusion and observed electron loss cone distribution is found from the second case. The strong depletion of electrons by EMIC waves predicted by the current theory was not found. In the third case the resonant energy goes beyond the instrument limit of electron detectors thus no conclusion is drawn.

This book was released on 1984 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental evidence is presented on the effect of the finite width of the current channel for the excitation of the current-driven ion-cyclotron instability. The results are in agreement with the nonlocal theory of Bakshi, Ganguli, and Palmadesso. Since their discovery over two decades ago, ion-cyclotron waves have been an area of active research in the laboratory, in the ionosphere-magnetosphere, and in the solar corona. The current-driven ion-cyclotron wave instability received its first theoretical treatment in the (local) theory of Drummond and Rosenbluth, appropriate to a uniform, magnetized plasma, without magnetic shear, in which electrons drift along B field lines with the same drift velocity v(D), at all points in the plasma. Their treatment, however, could not allow, among other things, for the effect that the finite width of the current channel of most laboratory experiments has on the excitation of the instability. This has been considered in the nonlocal theories.
