Predicted density and velocity profiles as function of time for numerical models with different solar wind conditions (mass-loss rate , and ejection velocity v _SW). These models are computed allowing variations of one parameter, and letting the rest fixed. Orange profiles correspond to variations of of the pre-eruptive wind (panels a–b) and post-eruptive wind (panels c–d); and green profiles are obtained for different values of v _SW of the pre-eruptive wind (panels e–f), and post-eruptive wind (panels g–h). The variations of each parameter are shown by the color bars at the right side of the figure. The reference models are depicted with black lines, corresponding to a solar wind with v _SW = 650 km s⁻¹) and  = 9.27 × 10⁻¹⁵ M_ʘ yr⁻¹. The detailed description of the figure is given in the text.
