Core masses (solid lines) and envelope masses (dashed lines) as a function of time. Gray lines: model with no planetesimal fragmentation. Red lines: baseline model. Pink lines: model with
for ices at impact velocities of 3 km s−1. Blue lines: model where 
is calculated by a linear combination between 
for basalts at 3 km s−1
and 
for ices at 3 km s−1.
