Relations estimated at shock discontinuities excited by coronal mass ejections
Eselevich, M. V.; Eselevich, V. G.
An analysis of SOHO/LASCO C3 data shows that there are discontinuities in the radial profiles of the plasma density within limited regions in front of each of ten coronal mass ejections, which represent shocks. The shock velocities in various events reach V ≈ 800-2500 km/s. A comparison of the dependence of the AlfvenicMach number M
Some properties of the development of the perturbed zone and shock preceding a coronal mass ejection
Eselevich, M. V.; Eselevich, V. G.
SOHO/LASCO C2 and C3 data have been used to carry out a detailed study of the perturbed zone and shock that form as a coronal mass ejection (CME) moves away from the Sun, as a result of its interaction with the ambient solar wind. The event of January 4, 2002 is used as an example. The perturbed zone is most extensive along the direction of propag…
