Density and velocity profiles on three perpendicular axes (x, y, and z) through the CoM for models with decreasing wind speed from left to right (v_ini = 20 km s⁻¹, v_ini = 10 km s⁻¹, v_ini = 5 km s⁻¹) and with increasing eccentricity from top to bottom (e = 0.00, e = 0.25, e = 0.50). The solid and dotted vertical lines indicate the position of the AGB stars and of its companion, respectively. The density axes are scaled with respect to the input mass-loss rate for an optimal comparison.
