We report simulations regarding tidal disruption clouds orbiting spherically
symmetric compact boson stars in two different regimes. First we consider
clouds in three different bound orbits close to the boson star and analyze the
mechanisms of debris formation for these. We infer from the simulations that
the lifetimes of these hot-spots are longer for circularly orbiting clouds than
for clouds on eccentric orbits. Next we compare the evolution of more extended
and less dense clouds on circular orbits around a boson star and a
Schwarzschild black hole. As an outcome of the simulations we observe the
formation of a ring-like structure around the boson star endowed with a
spiralling shock structure and a constant thermal bremsstrahlung total
luminosity. This final configuration contrasts strongly with the black hole
scenario where the gas is totally captured behind the event horizon.
