Notes. M_c is the total initial mass of the cloud and R_c is its initial radius. α_t is the initial thermal virial ratio and Τ is the isothermal temperature of the cloud. Its initial free-fall time is given by τ_ff. Each SPH particle composing the total cloud has a mass of Δm. r_acc is the sink accretion radius that is connected to the critical density ρ_c via Δm. With respect to the new star formation scheme, sinks can accrete during a fixed time, t_acc, and seeds inside it form after reaching t_seed. Finally, sink creation tests can be overridden if the density reaches a too high value. This override is controlled by f_override.
