Scientific paper

Here I thoroughly discuss the hydrodynamics of matter reinserted by stars within young starburst regions with a central SMBH. I show that the thermalization of the kinetic energy provided by massive stars prevents, via powerful gaseous outflows, the accretion of the interstellar gas onto the host galaxy center and may result into three different hydrodynamic regimes: quasi-adiabatic with low accretion rates, strongly radiative with larger accretion rates and gravitationally bound. In the gravitationally bound regime the accretion rate reaches the maximum value because in this case all of the matter returned by stars within the starburst region remains gravitationally bound and are able to fuel the central SMBH. Which of the three possible regimes takes place, depends on the dynamical mass of the system, the starburst mechanical luminosity, mass deposition rate and radius. This scenario leads to a physical link between the central supermassive black holes and nuclear star formation in their host galaxies as it has been established in different sets of observations during the last decade.
