Disk-satellite interactions

TLDR

The authors calculate the rate of angular momentum and energy transfer between a disk and an orbiting satellite around a central mass. They apply this calculation to the interaction between Jupiter and its protoplanetary disk. The study shows that Lindblad resonances increase the satellite’s orbit while corotation resonances decrease it, and that the rapid angular‑momentum transfer would have altered both the disk structure and Jupiter’s orbit within a few thousand years. Published in The Astrophysical Journal (Oct 1980, DOI 10.1086/158356) with keywords such as Jupiter, momentum transfer, and resonances.

Abstract The rate at which angular momentum and energy are transferred between a disk and a satellite which orbit a central mass is calculated. It is shown that the angular momentum and energy transfer at Lindblad resonances tends to increase the satellite's orbit to lowest order in eccentricity, whereas the transfer at corotation resonances tends to decrease it. The results are applied to the interaction between Jupiter and the protoplanetary disk. The angular momentum transfer is shown to be so rapid that substantial changes in both the structure of the disk and the orbit of Jupiter must have taken place on a time scale of a few thousand years.
