Migration of rocks, planets and hurricanes in protoplanetary discs

Sijme-Jan Paardekooper (University of London)

IPAG Seminar Room - IPAG

Planets are born in circumstellar discs of gas and dust. It has been known for more than 35 years that satellites embedded in gaseous discs can be very mobile. The discovery of Hot Jupiters, giant planets orbiting extremely close to their central star, showed that planets can indeed move away from their place of birth. However, incorporating migration in planet formation models has been far from trivial, since models predicted that inward migration should be extremely efficient, and therefore all gaseous planets should be Hot Jupiters or Hot Neptunes. Moreover, it was realized that all planetary building blocks are in fact subject to migration. I will discuss recent progress on these topics and how it may help to construct a global picture of how planets are formed.
