3D RMHD simulations of the Gamma-ray binaries by Maxim V. Barkov et al. on Wednesday 23 November

We performed fully 3D relativistic magnetohydrodynamical simulation of

"stellar wind"-"pulsar wind" interaction in massive binary system, taking into

account various possible pulsar geometries ("Frisbees", "Cartwheels" and

"Bullets" - a reference to the direction of the pulsar's spin, plane of the

orbit and the direction of motion), and various wind trust ratios. The

resulting intrinsic morphologies, and different lines of sight, lead to

significantly different orbital-phase dependent flow shapes. For the case of

companion-dominated wind in the "Bullets-Cartwheel" configuration, the tails

length - region of unshocked pulsar wind - can change by an order of magnitude

over quarter of the orbit.
