WebDec 9, 2016 · The magnetosonic speed depends both on the sound and the Alfvén speeds. When the relative shock speed, calculated in the shock frame of reference, is greater than the magnetosonic speed, the shock is classified as a fast shock. For the other case, the shock is said to be slow. If the shock propagates away from the Sun, it is … WebIn this context, it clear that this database's "magnetosonic speed" is actually the magnetosonic speed for the fast-mode wave for the case of magnetic field vector …

WebJan 11, 2024 · Fast magnetosonic waves can interact with the local radiation belt electron population resonantly and nonresonantly, efficiently accelerating some particles to high energies while scattering others into the loss cone (e.g., ... A magnetosonic wave, also called a magnetoacoustic wave, is a linear magnetohydrodynamic (MHD) wave that is driven by thermal pressure, magnetic pressure, and magnetic tension. There are two types of magnetosonic waves, the fast magnetosonic wave and the slow magnetosonic … See more In an ideal homogeneous plasma of infinite extent, and in the absence of gravity, the fast and slow magnetosonic waves form, together with the Alfvén wave, the three basic linear MHD waves.
