Summary of the proton core (red vertical ticks), proton beam (green crosses), and alpha particle (blue plus signs) properties. First row: radial velocities and densities, which influence their mass fluxes in the second row. The particle mass fluxes, when combined with their respective tangential wind speeds (shown in the third row), produce the AM fluxes in the fourth row. Top panels: the particle densities have the corresponding symbol shapes, but are grey in colour and connected by thin coloured lines. Bottom panels: the magnetic stresses from Eq. (5) are shown with black horizontal ticks in comparison to the particle AM fluxes. The time of perihelion during each orbit is highlighted with a green dotted vertical line. Fast wind streams (F1 and F2) and slow wind streams (S1 and S2) are highlighted in orange and cyan, respectively.
