A Self-Sustained Black Hole Engine, Powered by Tidal Disruption of Stars

• A self-sustained black hole engine, powered by tidal disruption of stars, is modeled as a central star cluster interacting with molecular clouds, where stars are disrupted by the black hole's gravity and feed it with gas, causing episodic brightening.
• The model shows that as stars and clouds concentrate near the black hole, tidal disruption rates increase, leading to a steady-state where the black hole maintains an equilibrium by inhibiting disruptions through star collisions.
