Notes. Columns from left to right: mass of the cometesimals, mass dust-to-ice ratio (0 for pure dust and ∞ for pure ice), density of the pebble, and final filling factors at the end of collapse. The initial compact pebble size is 1 cm in each simulation. 100 representative particles were used. The typical uncertainties of the final filling factors are ≲15%. The individual uncertainties can reach 50% in the high-mass cloud for pure dust pebbles with φ0 = 0.001, because of the presence of barely compressed pebbles.

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.
