Mirror mode structures near Venus and Comet P/Halley

Zhang, T. L.; Baumjohann, W.; Volwerk, M. +4 more

In this paper, we study where mirror mode structures are generated near unmagnetized solar system bodies (Venus and comet P/Halley measured in situ by Venus Express and Giotto). To estimate the location of the mirror mode source region at Venus, we apply a turbulent diffusion model of mirror mode structures, which has already been successfully tes…

Observation of shocks associated with CMEs in 2007

Zhang, T. L.; Balikhin, M. A.; Taktakishvili, A. +1 more

The interaction of CMEs with the solar wind can lead to the formation of interplanetary shocks. Ions accelerated at these shocks contribute to the solar energetic protons observed in the vicinity of the Earth. Recently a joint analysis of Venus Express (VEX) and STEREO data by Russell et al. (2009) have shown that the formation of strong shocks as…
