[69.11] Bow Shocks Driven By Anisotropic Winds

F.P. Wilkin (IPAC)

Analytic solutions are presented for non-axisymmetric bow shocks driven by an axisymmetric, misaligned wind moving with respect to the ambient medium. These steady-state, thin-shell models exactly conserve vector momentum, and are described by two parameters: (1) the degree of wind asymmetry, and (2) the angle of inclination of the wind symmetry axis with respect to the direction of stellar motion. The shape of the bow shock is shown for a variety of these parameters. The model is an example of a large class of non-axisymmetric colliding wind solutions that may be obtained by the same method.
