EVIDENCE SUPPORTING THEORY OF PLANET SYSTEM FORMATION

Newly formed stars can ‘swallow’ planets, as shown in this apod sketch. This would correspond to rather major movement of a planet after formation.

Planets must form quickly or not at all for some stars, as shown in these images from HST.

These images show details of circumstellar disks around young stars, with concentrations of mass that could ultimately result in planet formation.
