Cyclic reformation of a quasi-parallel bow shock at Mercury: MESSENGER observations

Mhd Turbulence in Saturn's Magnetosheath Downstream of a Quasi Parallel Bow Shock

The origin of the MHD turbulence downstream of a quasi parallel shock is investigated using plasma and magnetic eld data taken by Voyagers 1 and 2 during their outbound traversals of the Saturn's magnetosheath. The characteristics of the waves observed in that region are compared with those of the waves present: (i) downstream of a quasi perpendicular shock; (ii) in the foreshock. The last comp...

Non-stationarity of the quasi-perpendicular bow shock: comparison between Cluster observations and simulations

We have performed full particle electromagnetic simulations of a quasi-perpendicular shock. The shock parameters have been chosen to be appropriate for the quasiperpendicular Earth’s bow shock observed by Cluster on 24 January 2001 (Lobzin et al., 2007). We have performed two simulations with different ion to electron mass ratio: run 1 withmi/me = 1840 and run 2 withmi/me = 100. In run 1 the gr...

Direct measurement of the cross-shock electric potential at low plasma β, quasi-perpendicular bow shocks

We use the Cluster EFW experiment to measure the cross-shock electric field at ten low β, quasi-perpendicular supercritical bow shock crossings on March 31, 2001. The electric field data are Lorentz-tranformed to a Normal Incidence frame (NIF), in which the incoming solar wind velocity is aligned with the shock normal. In a boundary normal coordinate system, the cross-shock (normal) electric fi...

Simulation of a Perpendicular Bow Shock

Mach number cases, whose laminar structures have been adequately described by magnetosonic Simulations of a high Mach number shock with wavetrains that scale as C/mpe ITidman and Krall, parameters typical of the earth's bow hock have 1971). Computer simulations including both been performed using a hybrid (particle ions, electron and ion scales, have significantly fluid electrons) code. The sim...
