Webb1 juli 2024 · The tearing mode instability is one important mechanism that may explain the triggering of fast magnetic reconnection in astrophysical plasmas such as the solar corona and the Earth's magnetosphere. Webbplasma starts to form a current sheet, it will gradually become unstable to tearing modes. These tearing modes will evolve in a current sheet that continues to be compressed and stretched by external ﬂows. This could for instance occur during the development of a solar ﬂare (Low & Wolfson 1988) or in substorms in the magnetotail (Baker etal ...

WebbInstability: the existence of an instability is determined by calculating the growth rate of an infinitesimal perturbation. If this growth rate is positive, the perturbation is unstable. Mode: a (normal) mode is a (global) solution of a (linear) evolution equation. Typically, this solution is a (standing or propagating) wave.

Webb摘要： Nonlinear interaction between tearing modes (TM) and slab ion-temperature-gradient (ITG) modes is numerically investigated by using a Landau fluid model. It is observed that the energy spectra with respect to wavenumbers become broader during the transition phase from the ITG-dominated stage to TM-dominated stage.
