The scattering of small bodies in planetary systems

Another piece of evidence for the scattering of material in exo-planetary systems comes from observations of evolved stars. 25% of DA white dwarfs show unexpected metal pollution (Zuckerman et al. 2003), whilst 1-3% of DA white dwarfs with cooling ages less than 0.5Gyr have excess emission in the in ...

final stages of planet formation

Runaway accretion in a disk of small bodies resulted in a tiny fraction of the bodies growing much larger than all the others. T ...
