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 Keplerian gas disk. This torque and Corotation Torque are the contributers to Type I Planetary Migration.

Lindblad resonances (Inner and Outer) affect Spiral Galaxy dynamics as well.
