Spatio-temporal evolution of the ion density. Numerical parameters as for Fig. 1 .
Electron distribution function at the end of the simulation shown in Figs. 1 and 2 . Panels from top to bottom correspond to , and .
Temporal evolution of at the probe, the maximum value of within the computational domain and . Numerical parameters as for Fig. 1 .
Comparison of electron and ions density profiles obtained with stationary and non-stationary theories. Numerical parameters as for Fig. 1 .
Electron trajectories in the plane. The trajectories are found by integrating Eq. (22) with the potential obtained from the Vlasov-Poisson simulation.
Difference of the maximum density values computed with the direct Vlasov code and stationary theory versus the probe radius. The simulation parameters are (blue crosses) and (red circles).
