Lynden-Bell mechanism

(a model for galaxy bar formation)

The Lynden-Bell mechanism is a model for the formation of bars in spiral galaxies, essentially showing how interactions between orbiting stars can synchronize their orbits under the conditions of the center of a galaxy. The mechanism was recently suggested as a possible alternate explanation for the distribution of extreme trans-Neptune objects that recently motivated the current Planet-Nine concept.
