Electrostatic Solitary Wave
In space physics, an electrostatic solitary wave (ESW) is a type of Electromagnetism, electromagnetic soliton occurring during short time scales (when compared to the general time scales of variations in the average electric field) in Plasma (physics), plasma. When a rapid change occurs in the electric field in a direction parallel to the orientation of the magnetic field, and this perturbation is caused by a unipolar or dipolar electric potential, it is classified as an ESW. Since the creation of ESWs is largely associated with turbulent Fluid dynamics, fluid interactions, some experiments use them to compare how Chaotic mixing, chaotic a measured plasma's mixing is. As such, many studies which involve ESWs are centered around turbulence, chaos, instabilities, and magnetic reconnection. History The discovery of Soliton, solitary waves in general is attributed to John Scott Russell in 1834, with their first mathematical conceptualization being finalized in 1871 by Joseph Valentin ...

Space Physics
Space physics, also known as space plasma physics, is the study of naturally occurring plasmas within Earth's upper atmosphere and the rest of the Solar System. It includes the topics of aeronomy, aurorae, planetary ionospheres and magnetospheres, radiation belts, and space weather (collectively known as solar-terrestrial physics). It also encompasses the discipline of heliophysics, which studies the solar physics of the Sun, its solar wind, the coronal heating problem, solar energetic particles, and the heliosphere. Space physics is both a pure science and an applied science, with applications in radio transmission, spacecraft operations (particularly communications and weather satellites), and in meteorology. Important physical processes in space physics include magnetic reconnection, synchrotron radiation, ring currents, Alfvén waves and plasma instabilities. It is studied using direct in situ measurements by sounding rockets and spacecraft, indirect remote sensing of elect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
