SP-345 Evolution of the Solar
System
FIGURE 13.6.4.- Hetegonic effects in
the Saturnian ring system. Dollfus' photometric profile compared with
Mimas' orbital distance reduced by a factor 2/8 (or 0.65). Cassini's
division may be the "hetegonic shadow" of Mimas. In the left comer,
the photometric profile is turned upside down. and reduced by the
factor 2/3 ("ring's own. shadow"). The rapid drop in intensity
between the B ring and C ring coincides with
the beginning of this shadow.
