Simulated relative density (grey scale) and selected magnetic field lines during the eruption of all CMEs, in the case of: first row – single eruption (ejected into the slow wind (SW)); second row – eruption + stealth (slow wind); third row – double eruption (slow wind); fourth row – single eruption (faster wind); fifth row – eruptions in the faster wind resulting from applying the same shearing speed that created a stealth ejecta in the slow wind case. The relative density is , where ρ₀ is the density of the initial relaxed state before the shear. The time t_sim is counted from the start of shear. The arrows are used in the text to indicate plasma blobs. Movies are available online.
