Figure 1. Profiles of the plasma density calculated for the stationary state
versus the length of the magnetic field line given in the nightside
auroral magnetosphere. The solid and dotted
(dashed and dash-dot) lines are shown for the thermal (auroral) protons and
electrons, respectively.
The curves are shown for the case where
Dr=100 km,
E
=10 mV m-1,
and
W/(nkBT2)=1
10-3 at
s=0.
Besides,
n1/n3=10 at the top of the given
magnetic field line (s=sm) for
t=0.
