Generation of Electron Plasma Waves in the Upstream Solar Wind
Electron plasma waves with amplitudes as high as 10 mV/m have been measured in the electron foreshock region of the earth's bow shock. It is shown that a population of stable suprathermal electrons of the type observed can produce the measured level of enhanced fluctuations without becoming unstable. The steady state wave level is given by the balancing between emission and absorption. The appa...
متن کاملThe Solar Wind Power from Magnetic Flux
Observations of the fast, high-latitude solar wind throughout Ulysses’ three orbits show that solar wind power correlates remarkably well with the Sun’s total open magnetic flux. These observations support a recent model of the solar wind energy and particle sources, where magnetic flux emergence naturally leads to an energy flux proportional to the strength of the large-scale magnetic field. T...
متن کاملElectromagnetic alpha/proton instabilities in the solar wind
The average flow speed of alpha particles relative to protons in the solar wind is observed to be of the order of or less than the Alfven speed. This flow, if sufficiently large, can lead to two distinct types of electromagnetic alpha/proton instabilities: magnetosonic and Alfven. Spatially homogeneous two-dimensional hybrid simulations of collisionless plasmas are used to study these growing m...
متن کاملfocus on communication in iranian high school language classes: a study of the role of teaching materials in changing the focus onto communication in language classes
چکیده ارتباط در کلاس به عوامل زیادی از جمله معلمان، دانش آموزان، برنامه های درسی و از همه مهم تر، مواد آموزشی وابسته است. در تدریس ارتباطی زبان که تاکید زیادی بر توانش ارتباطی دارد، کتاب درسی به عنوان عامل موثر بر پویایی کلاس محسوب میگردد که درس ها را از طریق فراهم آوردن متن ارتباط کلاسی و هم چنین نوع تمرین زبانی که دانش آموزان در طول فعالیت های کلاسی به آن مشغول اند، کنترل می کند. این حقیقت ک...
15 صفحه اولTurbulent Spectra in the Solar Wind Plasma
Observations of interstellar scintillations at radio wavelengths reveal a Kolmogorovlike scaling of the electron density spectrum with a spectral slope of −5/3 over six decades in wavenumber space. A similar turbulent density spectrum in the solar wind plasma has been reported. The energy transfer process in the magnetized solar wind plasma over such extended length-scales remains an unresolved...
