The birth of a planet

partially translated by @ulaulaman from a post by @_starblogger_
When I write about the Nice model, I explain how a group of researchers try to explain the birth of our Solar System. The approach of the group is to design some simulations about the dynamics of the whole Solar System. This approach is very used in physics, in particular when calculation by hand are too complicated. So, today I would propose you a video with the interview to a new group that perform some simulations in order to explain how a planet could born. The group, leaded by Sally Dodson-Robinson is
(...) carrying out a series of computer simulations of the proto-stellar disks. The simulations provide some important parameters, such as the turbulence and the temperature of the disc, which influence how and where the planets are formed. In a disk with a high percentage of turbulence, the particles forming the planetesimals move very quickly and go away from each other. At the other hand, in a less turbulent situation, there will be a much more probability that the particles collide and are aggregated together in order to give rise to future planets. In 1988, it was known only an extrasolar planet, and today almost 2400 waiting to be confirmed. Therefore, understanding those favorable conditions for the formation of a planet will allow astronomers to discover more and more of them and, at the same time, will provide important new clues about the birth and evolution of the Earth and then of the Solar System.(1)
