Hace 3 días · Kurzfassung. We statistically study various properties of low-frequency waves such as frequencies, wave numbers, phase velocities, and polarization in the plasma rest frame in the terrestrial foreshock. Using Cluster observations the wave telescope or k-filtering is applied to investigate wave numbers and rest frame frequencies.
Hace 4 días · Modified. April 26, 2024. The uploaded folder consists of the numerical simulation data and analyses routines of two-fluid JOANNA code that studied the Alfvén pulse-driven spicule-like jets in the presence of thermal conduction and Ion-neutral collision.
Hace 5 días · Le plus important est celui où la matière, qui est accrétée par la protoétoile, perd de son moment cinétique. Une explication possible, suggérée par Hannes Alfvén, est que le moment cinétique est perdu par le vent solaire lors de sa phase T Tauri.
Hace 22 horas · Hannes Alfvén won the Nobel Prize for his development of magnetohydrodynamics (MHD) the science that models plasma as fluids. This book lays down the ground work, but also shows that MHD may be inadequate for low-density plasmas such as space plasmas. Astronomy and astrophysics.
Hace 4 días · The origin of the observed fast Alfvén wave can be either directly generated or induced by other instabilities (waves). This will be investigated in the future, but here we want to mention that we have observed fluctuations near the lower-hybrid frequency from our plasmas.
