Figure 4. Vertical distribution of particles loosely coupled to the gas (τΩ> 1, corresponding to large particles). The dashed line shows the expected distribution for particles tightly coupled to the gas, neglecting oscillations, while the dotted line shows the analytical model for particles loosely coupled to the gas (see Equation (23)), which shows an excellent agreement with LIDT3D. Note that the particle’s scale height diminishes with the particle’s stopping time in agreement with Youdin & Lithwick (2007).
