Abstract One dimensional hybrid simulations of rotational discontinuities (RDs) are presented. When the angle between the discontinuity normal and the magnetic field (θ BN) is 30°, the RD broadens into a quasi-steady state of width 60 – 80 c/ωi. The hodogram has a characteristic S-shape. When θ BN = 60°, the RD is much narrower (10 c/ωi). For right handed rotations, the results are similar to θ BN = 30°. For left handed rotations, the RD does not evolve much from its initial conditions and the S-shape in the hodogram is much less visible. The results can be understood in terms of matching a fast mode wave-like structure upstream of the RD with an intermediate mode one downstream.
