Abstract
Using the stochastic collection equation we find that the time scale for rain out of liquid iron in a Saturn mass protoplanet is rapid compared with other evolutionary time scales and hence iron protoplanetary core formation is inevitable. The survival of this core during subsequent protoplanetary evolution and the consequences of the rain-out on the evolution are also discussed.
