Fig. 3

Grainvelocities (left axis) and Hall factor (right axis) as a function of the grain radius for a gas proton density nH of 104 cm −3 (left), 106 cm−3 (middle) and 108 cm−3 (right). The ambipolar diffusion velocity VAD is fixed and equal to cs∕10 = 20 m s−1. We present the components V∥ parallel to the infall (magenta) and V⊥ perpendicular to the infall and to the magnetic field direction (green). For comparison, the turbulent relative velocities ΔV from Fig. 2 are overplotted in dotted blue lines. The grain specific density is 3 g cm −3.
