HZ planets around brown dwarfs?

Tidal evolution of planets around brown dwarfs

If habitable planets can exist around brown dwarfs, they are subject to strong tidal forces that cause orbital migration. Various other factors differ from stars, e.g. brown dwarfs spin up as they age (due to central condensation and less efficient magnetic braking), and cool down (no hydrogen-1 fusion).

Maybe habitable lifetimes of ~1 Gyr around brown dwarfs above 0.05 solar masses are possible...
