Planetary bow shocks: Asymptotic MHD Mach cones
A direct approach for determining the asymptotic MHD Mach cone is formulated and solved. An implicit analytical solution enables the calculation of the asymptotic downstream slope of MHD Mach cones at any clock angle for arbitrary Ms , Ma , and θbv . The solution obtained includes all previously known symmetric cases. The elongation and shift of the asymptotic fast mode shock cross-section are ...
متن کاملHigh-temperature Processing of Solids in Planetary Embryo Bow Shocks
Introduction: Dynamical interactions between planetoids and planets are a natural consequence of planet formation and can place large bodies on eccentric and/or inclined orbits [1-3]. If gas is present during scattering events, as is suggested by recent models of Mars’s low mass [3,4] and new age estimates for Mars’s formation [5], a wide range of nebular shocks can be produced. Any solids that...
متن کاملDirect 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...
متن کاملModelling Non-axisymmetric Bow Shocks
I present an extension of the thin layer approximation to non-axisymmetric bow shocks. By choosing a suitable set of curvilinear coordinates that matches the geometry of a generally distorted bow shock surface, I derive the fluid equations for the flow. Analytical expansions are given for the matter flow near the bow shock stagnation point. Numerical solutions are also obtained, by using a revi...
متن کاملIdentifying Bow Shocks with Hα Allsky Surveys
OB–stars have the highest luminosities and strongest stellar winds of all stars, which enables them to interact strongly with their surrounding ISM, thus creating bow shocks. These offer us an ideal opportunity to learn more about the ISM. They were first detected and analysed around runaway OB–stars using the IRAS allsky survey by van Buren et al. (1995). Using the geometry of such bow shocks ...
