On the resolution of the phase space density required to obtain a specified accuracy of the solar wind bulk velocity
Podesta, John J.
Plasma measurements with significantly improved accuracy and time resolution are needed to advance knowledge and understanding of plasma physical process in the magnetosphere and the solar wind. In this study, it is shown how small unresolved features in particle distribution functions can have significant impacts on the measurement of plasma bulk…
The nonlinear evolution of kinetic Alfvén wave with the ion acoustic wave and turbulent spectrum in the magnetopause region
Sharma, R. P.; Yadav, N.; Rinawa, M. L. +1 more
The mutual nonlinear interplay of kinetic Alfvén wave (KAW) and ion acoustic wave, for the high-β plasma (i.e., me/mi ≪ β ≪ 1, where β is thermal to magnetic pressure ratio) in the magnetopause, has been considered in the present study. A set of dimensionless nonlinear Schrödinger equations has been derived taking into accoun…
Can ring current stabilize magnetotail during steady magnetospheric convection?
Ganushkina, N.; Dubyagin, S.; Liemohn, M. +1 more
The present study investigates the role of the ring current in stabilizing the magnetotail during steady magnetospheric convection (SMC) events. We develop a method for estimation of the symmetric ring current intensity from the single spacecraft magnetic field observations. The method is applied to a large number of SMC events identified using th…
Interpreting Ulysses data using inverse scattering theory: Oblique Alfvén waves
Wheeler, Harry R.; Reynolds, M. A.; Hamilton, R. L.
Solitary wave structures observed by the Ulysses spacecraft in the solar wind were analyzed using both inverse scattering theory and direct numerical integration of the derivative nonlinear Schrödinger (DNLS) equation. Several of these structures were found to be consistent with soliton solutions of the DNLS equation. Such solitary structures have…
