Left: entropy distribution in a cross-sectional plane of model L15-1 at 1000 ms after bounce. The plane is chosen such that it contains the final vectors of the NS kick velocity induced by aspherical mass ejection (v_ns, long white arrow pointing to the right) and of the kick velocity caused by anisotropic neutrino emission (v_ns,ν, short white arrow pointing towards the 7 o’clock position). The relative lengths of both arrows correspond to the absolute values of the velocities (v_ns ≈ 160 km s^-1 and v_ns,ν ≈ 5 km s^-1), but the short arrow for v_ns,ν is stretched by a factor of 5 for better visibility. A yardstick in the lower left corner of the figure indicates a spatial length scale of 2000 km. The contribution of anisotropic neutrino emission to the total NS kick velocity is clearly a small effect. Right: time evolution of the neutrino-induced kick velocity v_ns,ν and of the angle α_kν between v_ns and v_ns,ν. The final velocities point roughly in opposite directions.
