This process takes place over millions of years - forming larger and larger objects until a planet eventually takes shape. '¨'¨Recently, Sally Dodson Robinson of the University of Texas at Austin ran a simulation that modeled the formation of the above-mentioned protostellar disks. 'The simulations model important factors such as the turbulence and temperature of the disk, which affect how and where planets form,' she explained. ''¨In a disk that is too turbulent, the particles move too fast and bounce off each other. Less turbulence means a greater chance for them to collide and stick together.''¨ According to Robinson, discoveries like this are a result of the complexity of the models and simulations - which effectively cover a timescale of millions of years. It should be noted that the considerable computation involved in the simulation was facilitated by the Ranger supercomputer...
