Bondi accretion is a theoretical model that describes how a massive object, such as a black hole, accumulates mass from a surrounding medium by gravitational attraction. This process is particularly significant in the context of supermassive black hole formation and growth, as it helps explain how these massive objects can gain enough mass to reach their enormous sizes over time. The model incorporates factors like the density of the surrounding material and the velocity at which it flows toward the black hole, illustrating the importance of accretion in the evolution of cosmic structures.
congrats on reading the definition of Bondi Accretion. now let's actually learn it.
