Correlation functions of small-scale fluctuations of the interplanetary magnetic field

Autor: Németh, Z., Facskó, G., Lucek, E. A.

The Interplanetary Magnetic Field shows complex spatial and temporal variations. Single spacecraft measurements reveal only a one dimensional section of this rich four dimensional phenomenon. Multi-point measurements of the four Cluster spacecraft pr

Reformation of an oblique shock observed by Cluster

Autor: Lefebvre, B., Seki, Y., Schwartz, S. J., Mazelle, C., Lucek, E. A.

Publikováno v: Journal of Geophysical Research (Space Physics) 114, 11107, 2009

On 16 March 2005, the Cluster spacecraft crossed a shock almost at the transition between the quasi-perpendicular and quasi-parallel regimes ($\theta_{Bn}=46^{\circ}$) preceded by an upstream low-frequency ($\sim$ 0.02 Hz in the spacecraft frame) wav

Supermagnetosonic jets behind a collisionless quasi-parallel shock

Autor: Hietala, H., Laitinen, T. V., Andréeová, K., Vainio, R., Vaivads, A., Palmroth, M., Pulkkinen, T. I., Koskinen, H. E. J., Lucek, E. A., Rème, H.

The downstream region of a collisionless quasi-parallel shock is structured containing bulk flows with high kinetic energy density from a previously unidentified source. We present Cluster multi-spacecraft measurements of this type of supermagnetoson

Study of reconnection-associated multi-scale fluctuations with Cluster and Double Star

Autor: Vörös, Z., Nakamura, R., Sergeev, V., Baumjohann, W., Runov, A., Zhang, T. L., Volwerk, M., Takada, T., Jankovičová, D., Lucek, E., Rème, H.

Publikováno v: Journal of Geophysical Research, vol. 113, A07S29, 2008

The objective of the paper is to asses the specific spectral scaling properties of magnetic reconnection associated fluctuations/turbulence at the Earthward and tailward outflow regions observed simultaneously by the Cluster and Double Star (TC-2) sp

Satellite Observations of Separator Line Geometry of Three-Dimensional Magnetic Reconnection

Autor: Xiao, C. J., Wang, X. G., Pu, Z. Y., Ma, Z. W., Zhao, H., Zhou, G. P., Wang, J. X., Kivelson, M. G., Fu, S. Y., Liu, Z. X., Zong, Q. G., Dunlop, M. W., Glassmeier, K-H., Lucek, E., Reme, H., Dandouras, I., Escoubet, C. P.

Publikováno v: Nature Physics advance online publication, 24 June 2007

Detection of a separator line that connects magnetic nulls and the determination of the dynamics and plasma environment of such a structure can improve our understanding of the three-dimensional (3D) magnetic reconnection process. However, this type
