Bow shock characteristics from magnetic field observations
Abstract. Based on the magnetohydrodynamic (MHD) shock jump condition (Rankine-Hugoniot relation), we develop a tool to determine the relationship between the density jump, Alfven Mach number and the solar wind plasma beta directly from magnetic field observations across the shock. The presented method is a useful tool to characterize the bow shock around planets, where plasma data are often limited or even not available. In particular in view of the ongoing Bepi-Colombo mission the tool can help to diagnose and characterize the bow shock during the planetary flybys.

Short summary
Here we present a useful tool to diagnose the bow shock condition around planets on basis of magnetic field observations. From the upstream and downstream shock normal angle of the magnetic field, it is possible to approximate the relation between compression ratio, Alfvenic Mach number and the solar wind plasma beta. The tool is particularly helpful to study the solar wind conditions and bow shock characteristics during the planetary flybys of the ongoing BepiColombo mission.
