Abstract Gravitational settling time of solid grains in a gaseous protoplanet has been calculated for three different initial grain sizes using the distribution of the physical variables inside the protoplanet, values of the physical variables at different depths being obtained by solving the structure equations. In all cases the sedimentation time is found to be short, in agreement with that obtained by others with different approach.

    Highlights ► Gravitational settling time of solid grains in a gaseous protoplanet. ► Distribution of the physical variables. ► Protoplanets can form in a time short on astronomical time scale.
