Left: coefficients of the viscosity of charged particles (, blue line) and neutrals (, orange lines), and the thermal conductivity of neutrals (, green lines), in units of m2 s−1, as from Eq. (14). The neutral viscosity and thermal conductivity coefficients are limited to 109 m2 s−1. Right: ion-neutral (νin, blue lines), neutral-ion (νni, orange line) collision frequencies, and frequencies associated with waves: fast magneto-acoustic (ωfast, green lines), in-plane Alfvén for “L1” shear (, red lines), acoustic in the neutral fluid (ωcn, black line) as functions of height. Values for the model with the original density contrast model are shown with solid lines, and for the enhanced density contrast with dotted lines.
