20 de may. de 2024 · This study models relativistic plasma wave interaction in magnetar magnetospheres with force-free electrodynamics simulations. For propagation along curved magnetic field lines, we observe the continuous conversion of Alfvén waves (AWs) to fast magnetosonic (FMS) waves.
16 de may. de 2024 · The Alfvén Transition Zone observed by the Parker Solar Probe in Young Solar Wind -- Global Properties and Model Comparisons. The transition from subAlfvénic to superAlfvénic flow in the solar atmosphere is examined by means of Parker Solar Probe (PSP) measurements during solar encounters 8 to 14.
22 de may. de 2024 · Murabito and colleagues focused on one of the leading explanations for this process, which invokes so-called Alfvén waves . These are low-frequency electromagnetic waves in a plasma that travel along the plasma’s magnetic field and induce a transverse motion in which the fluid and the magnetic field move together.
22 de may. de 2024 · We report the first measurements of drift-Alfvén wave polarization in a hot, magnetically confined plasma. The breakthrough is enabled by a novel methodology developed from gyrokinetic theory, utilizing fluctuations of electron temperature and density.
Hace 4 días · Abstract. While much about Alfvén eigenmode (AE) stability has been explored in previous and current tokamaks, open questions remain for future burning plasma experiments, especially regarding exact stability threshold conditions and related isotope effects; the latter, of course, requiring good knowledge of the plasma ion composition.
Hace 3 días · This model solves the magnetohydrodynamic (MHD) equations with separate ion and electron temperatures and two equations for the Alfven wave turbulent energy densities propagating along and counter the magnetic field lines. The Alfvenic Poynting flux is assumed to be emanating from the chromosphere.
