Notes. (a) Domain size in the radial, azimuthal, and vertical dimensions, where H is the gas scale height.(b) Stokes number of the dust particles. (c) Dimensionless parameter quantifying the strength of the gas pressure gradient as defined by Bai & Stone (2010b). (d)Time at which dust self-gravity is introduced, where PK is the Keplerian orbital period. (e)Time over which the strength of the dust self-gravity is gradually enhanced.(ƒ) Time at which simulation ends. (g) Threshold dust density for sink particle creation, expressed in units of the mid-plane gas density ρg,0. (h) Sink particle creation begins at t = 14.2 PK instead of at 15 PK because of memory limitations.
