The fast and slow modes are compressive and grow into shock waves, while the Alfven wave is incompressive.
From a series of in-depth, 3D numerical studies, considering, in turn, three of the most promising heating processes (Taylor relaxation, braiding and Alfven wave heating) at their particular spatial and temporal scales, we will determine:- the cadence of the heating: low-frequency ( bursty ) vs high-frequency ( near-continuous );- the range of parameters for which heating is most efficient (i.
Since the 1970s, scientists have known that movement in the solar wind often has the characteristics of a kind of wave called an Alfven wave.
The additional studies of Alfven wave dynamics, the effect of energetic particles or collisionless reconnection and proton and alpha particle heating will also impact space and astrophysical plasma physics.
