Field line resonances in a cylindrical plasma

An experimental study of the response to an impulsive driver in a low beta helium plasma is presented. Field line resonance ~FLR! spectra are recorded and compared to an ideal magnetohydrodynamic ~MHD! theory with finite ion cyclotron frequency corrections. The agreement between observed and predicted values is generally within the frequency resolution of the measurements except for the lowest ...

Nonaxisymmetric magnetic field generation in rapidly rotating late-type stars

Abstract. Recently the discovery of the “flip-flop” phenomenon, by which a predominant “active” longitude jumps by about 180◦, on several rapidly rotating late-type stars has directed attention to the issues surrounding the presence of large-scale nonaxisymmetric magnetic fields in these objects. Here we study nonlinear mean field dynamo models with quasi-cylindrical rotation laws, acting in sp...

Resonances of the helium atom in a strong magnetic field

We present an investigation on the resonances of a doubly excited helium atom in a strong magnetic field covering the regime B = 0 − 100 a.u. A full-interaction approach which is based on an anisotropic Gaussian basis set of one-particle functions being nonlinearly optimized for each field strength is employed. Accurate results for a total of 17 resonances below the threshold of consisting of H...

Field line resonances in discretized magnetospheric models: an artifact study

For more than two decades numerical models of the Earth's magnetosphere have been used successfully to study magnetospheric dynamic features such as the excitation of ULF pulsations and the mechanism of ®eld line resonance. However, numerical formulations simplify important properties of the real system. For instance the Alfve n continuum becomes discrete because of a ®nite grid size. This dis...

Influences of magnetic field in viscoelastic fluid

This communication influences on magnetohydrodynamic flow of viscoelastic fluid with magnetic field induced by oscillating plate. General solutions have been found out for velocity and shear stress profiles using mathematical transformations (Integral transforms). The governing partial differential equations have been solved analytically under boundary conditions u(0,t)=A_0 H(t)sinΩt and u(0,t)...
