We briefly describe the main theoretical results of the KH instability obtained in the linear approximation. Analysis of observational data, confirming the occurrence of the KH instability in magnetic formations of the solar coronal plasma and on the daytime magnetopause, was mainly performed in the ...

In both of these two different configurations of the AB interface, the KH instability can be triggered and measured. It is found that the change to the annular interface geometry is marked by a ∼10% drop in Ωc [39]. In contrast, in a B → A transition, where Ib is slowly swept...
Definition Kelvin-Helmholtz instability arises because of shear along an interface between two different fluids. Being related to turbulence and transition phenomena, it also describes the onset of ocean wave formation, jetting instabilities, and cloud formation. In microfluidics, it is commonly seen in...

Context.Magnetic null points are associated with high-energy coronal phenomena such as solar flares and are often sites of reconnection and particle acceleration. Dynamic twisting of a magnetic null point can generate a Kelvin-Helmholtz instability (KHI) within its fan plane and can instigate spine-...
induced magne-topause for low solar activity. During high solar activity, however, there could occur conditions at theinduced magnetopause which are in favour of the nonlinear evolution of the instability. For this situation,we estimated roughly a growth rate for planetary oxygen ions of about ...
