Many planetary systems prematurely evaporate into thin air
When stars are born, large clouds of gas and dust form that are known as circumstellar discs. Research by PhD candidate Francisca Concha-Ramírez shows that strong radiation from neighbouring stars soon evaporates the dust in these discs, which can prevent planet formation at an early stage.
