Web25 de mai. de 2024 · The accretion of a gas particle can occur when it enters the accretion radius of a sink. To be accreted, the gas particle has to be gravitationally bound to the sink and its angular momentum has to be sufficiently low. In order to reliably resolve the accretion rates, the accretion radius of each sink is set to 0.1 au.
