What mechanism is cited as a possible cause for the inward migration of a Hot Jupiter?

Answer

Gravitational interactions with the remaining gas and dust in the protoplanetary disk or with other massive planets

Migration could occur either through the planet interacting with the surrounding protoplanetary disk, causing its orbit to decay, or through gravitational nudges from other massive bodies in the system.
