Notes. Columns denote the orbital disk radius r, the adopted flow solution (potential or Stokes), the particle radius s, the dimensionless stopping time τs = tsΩ, the minimal collision factor fcoll,min obtained from the results shown in Fig. 3, the maximum growth timescale tgr,max obtained from the results shown in Fig. 4 (unless denoted otherwise in the comment section), the corresponding planetesimal radius Rgr,max , and the planetesimal radius where pebble accretion starts RPA.
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.
Initial download of the metrics may take a while.
