Fig. 1


Particle Stokes numbers as a function of mass, in the midplane of an MMSN disk at 5 AU. Different lines show compact particles (red), porous aggregates with constant φ = 104 (yellow), and aggregates with a constant fractal dimension of 2.5 (green). For the solid lines, all drag regimes (Epstein, Stokes and Newton) have been taken into account, while the dashed lines indicate the results using only Epstein and Stokes drag. Horizontal lines indicate Ωts = 1 (where drift is fastest) and Ωts = α = 10-3 (where particles start to settle to the midplane).

Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.

Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
