Eddington rate

WebMass accretion by black holes (BHs) is typically capped at the Eddington rate, when radiation's push balances gravity's pull. However, even exponential growth at the Eddington-limited e-folding time t E ~ few × 0.01 billion years is too slow to grow stellar-mass BH seeds into the supermassive luminous quasars that are observed when the … Webthe Eddington accretion rate is the corresponding mass accretion rate. However, BHs can also release energy through mechanical channels (kinetic energy of jets and winds). The …
