Lindblad torque

(torque due to Lindblad resonances)

Lindblad torque (named for Swedish astronomer Bertil Lindblad) is a torque on an orbiting body due to orbital resonances known as Lindblad resonances. These apply in planets or planetoids orbiting in a (gas) Keplerian disk. This torque and corotation torque are the contributers to Type I migration.

Lindblad resonances (inner and outer) affect spiral galaxy dynamics as well.
