Abstract
We make use of the results of a one-ion model of McKenzie et al. (1997) to obtain the critical solution describing the acceleration of a two-ion solar wind. The model includes preferential heating of the heavy ion species and the temperature anisotropy expected if the heating is predominantly due to ion-cyclotron damping. The relationship of the model to the picture emerging from UVCS/SOHO observations is discussed.
