Fig. 3

Panel a: Density as shown in Fig. 1 as an orientation for the over plotted velocity vectors. The color-bar indicates the absolute value of the velocity of each vector in units of vK(R∗). Only the radial and polar component of the velocity vector have been taken into account. Panel b: Angular velocity Ω = uϕ/r (blue) and the radial velocity ur (red) in the equatorial plane as a function of the radius r. The y-axis on the left-hand side refers to Ω and the y-axis on the right-hand side refers to ur. All velocities are normalized to the Keplerian (angular) velocity at the surface of the star, . Both snapshots are taken after a time of 688 orbits.
