Web在太空物理研究中,一种被称作动理学阿尔芬波(kinetic Alfven waves)的波受到了极大的关注。这一波动可以视为宏观流体尺度(>10 7 千米)的阿尔芬波向微观离子尺度(~10 1 千米)的拓展。 Web31 jul. 2013 · The E φ of poloidal waves is aligned with the drift motion of particles, allowing a strong wave-particle resonance interaction. The resonance associated with the drift motion is considered important for dynamics of the ring current [ Southwood , 1976 ; Sibeck et al. , 2012 ] and radiation belt particles [ Schulz and Lanzerotti , 1974 ; Elkington et al. , 2003 ].
Three-wave coupling and parametric decay of kinetic Alfvén waves
WebKinetic Alfvén waves (KAWs), with a strong parallel disturbed electric field, play an important role in energy transport and particle acceleration in the magnetotail. On the basis of high-resolution observations of the Magnetospheric Multiscale (MMS) Mission, we present a detailed description of the acceleration process of electrons by KAWs in the plasma … Web11 apr. 2024 · We study the parametric decay instability of parallel-propagating Alfvén waves in a low-beta plasma using one-dimensional fully kinetic simulations. We focus for the first time on the conversion of the energy stored in the initial Alfvén wave into particle internal energy, and on its partition between particle species. kibbeh spice recipe

Web20 mrt. 2024 · By analyzing both the polarization and group velocity of perturbations in the shear regions, we identify them as Kinetic Alfvén Waves (KAWs). In the moderate amplitude run, kinetic effects distort the proton distribution function in the shear region.
