Bow shock — A bow shock is a boundary between a magnetosphere and an ambient medium. For stars, this is typically the boundary between their stellar wind and the interstellar medium.In a planetary magnetosphere, the bow shock is the boundary at which the… … Wikipedia
Bow shock (aerodynamics) — For other uses, see Bow shock. A blunt body fired from a gun against a supersonic flow in a wind tunnel, producing a bow shock. A bow shock, also called a detached shock, is a curved, stationary shock wave that is found in supersonic flow past a… … Wikipedia
Shocks and discontinuities (magnetohydrodynamics) — Shocks and discontinuities are transition layers where the plasma properties change from one equilibrium state to another. The relation between the plasma properties on both sides of a shock or a discontinuity can be obtained from the… … Wikipedia

Bipolar outflow — A bipolar outflow represents two continuous flows of gas from the poles of a star. Bipolar outflows may be associated with protostars (young, forming stars), or with evolved post AGB stars (often in the form of Bipolar nebulae). In the case of a… … Wikipedia
Heliosphäre — Die Heliosphäre ist der weiträumige, interplanetare Bereich um die Sonne, in dem der Sonnenwind mit seinen mitgeführten Magnetfeldern wirksam ist. In diesem Bereich des Sonnensystems verdrängt der Teilchenstrom der Sonne die interstellare Materie … Deutsch Wikipedia
Transonic — is an aeronautics term referring to a range of velocities just below and above the speed of sound (about mach 0.8–1.2). It is defined as the range of speeds between the critical mach number, when some parts of the airflow over an aircraft become… … Wikipedia
