Tidal effects in potentially habitable planets at the sub-stellar mass limit
Abstract
We studied the relevance of tidal effects along the formation and early evolution of rocky planets near a star with a mass close to the sub-stellar mass limit. We developed a set of $N$-body simulations that included the early contraction and spin up of the star, the distortions and dissipation from tidal forces and general relativistic effects, and neglected the interaction between the bodies involved and the gas during the first Myr. We found that the tidal effects allow the survival of a close-in planet population with masses $0.001<M/\mathrm{M_\oplus}<0.012$.
