Fig. 6

Evolution of the semimajor axis and eccentricity (through apoastron and periastron distances) of a 1.0 M_Io satellite for different satellite dissipations. Here the disk lifetime is 35 000 yr, and the disk density 1000 g cm⁻². The evolution is shown for two different initial satellite semimajor axes: 0.4 a_Io (top panel) and 0.6 a_Io (bottom panel).
