SP-345 Evolution of the Solar
System
FIGURE 23.2.1.- Complete ionization of
infalling gas. Gas falling in from infinity reaches the critical
velocity at rion (the critical
velocity sphere) and becomes partially ionized. It is rapidly
included in "superprominences" which, if 
, are almost completely ionized. Matter falling in at
low latitudes (a, b, and c) will be emplaced near the equatorial
plane and condense there. Matter arriving at the critical velocity
sphere at high latitudes (d) will be drawn into the central body.
Note that the processes a, b, and c do not necessarily interfere
because they may occur at different times or even simultaneously at
different longitudes.
