Observation of Large-Scale Kelvin-Helmholtz Instability Wave Driven by a Coronal Mass Ejection
Leon Ofman, Olga Khabarova, Ryun-Yong Kwon +3
The Kelvin-Helmholtz instability (KHI) can occur when there is a relative motion between two adjacent fluids. In the case of magnetized plasma, the shear velocity must exceed the l…
Electron-to-ion bulk speed ratio as a parameter reflecting the occurrence of strong electron-dominated current sheets in the solar wind
Olga Khabarova, Jörg Büchner, Neeraj Jain +3
Current sheets (CSs) are preferred sites of magnetic reconnection and energy dissipation in collisionless astrophysical plasmas. Electric currents in them may be carried by both el…
Current sheets, plasmoids and flux ropes in the heliosphere. Part II: Theoretical aspects
O. Pezzi, F. Pecora, J. le Roux +13
Our understanding of processes occurring in the heliosphere historically began with reduced dimensionality - one-dimensional (1D) and two-dimensional (2D) sketches and models, whic…
Automated identification of current sheets -- a new tool to study turbulence and intermittency in the solar wind
Olga Khabarova, Timothy Sagitov, Roman Kislov +1
We propose a new method of the automated identification of current sheets (CSs) that represents a formalization of the visual inspection approach employed in case studies. CSs are…
Evolution of the solar wind speed with heliocentric distance and solar cycle. Surprises from Ulysses and unexpectedness from observations of the solar corona
O. V. Khabarova, V. N. Obridko, R. A. Kislov +5
An extensive analysis of Ulysses observations of the solar wind speed V from 1990 to 2008 is undertaken. It is shown that the evolution of V with heliocentric distance r depends su…
Small-scale magnetic islands in the solar wind and their role in particle acceleration. Part 1: Dynamics of magnetic islands near the heliospheric current sheet
O. Khabarova, G. P. Zank, G. Li +4
Increases of ion fluxes in the keV-MeV range are sometimes observed near the heliospheric current sheet (HCS) during periods when other sources are absent. These resemble solar ene…
