The tidal evolution of planets orbiting brown dwarfs (BDs) presents an interesting case study because BDs' terrestrial planet forming region is located extremely close-in, in a region where tidal interactions are strong. To study the orbital evolution of planets around BDs, I coupled a standard equilibrium tidal model with evolutionary models of BDs.

As planetary systems are likely to host more than one planet, it's also interesting to study the dynamics of tidally driven multiple planet systems around BDs. In particular, eccentricity exchanges and resonances can have effects on the evolution of inner planets.
