    New Directions in Planet Formation

Scientific report: New Directions in Planet Formation

Ravit Helled, Anders Johansen, Chris Ormel



Description and aims

In organizing this workshop we had several key goals in mind:


  • Exchange of the latest results on planet formation topics, triggering future (collaborative) research
  • Introducing planet formation experts to the Netherlands
  • Introduce/entice younger people to planet formation topics and to the leading people in the field



We planned organizing the workshop early 2014. To fulfill the goal we conceived a program that was strong both content-wise (presentations on the state-of-the-art)and left room for interaction by having a 3h break in the middle each day (and many other long breaks). We were very happy about this design. During the 3h breaks smaller groups tackled specific research problem. These groups were made up of senior (professors) as well as junior scientist (PhDs), but in the end it was the junior scientists who had to give the presentation. We believe this design paid off. Although not every groupís research question is suited to provide a tangible result, at least one group, studying the likelihood to capture planets, considered submitting their work to a journal.


The open design of the workshop means not every of the around 50 participants could orally present their work. However, the 15 (mostly junior) participants that presented a poster had plenty of time to promote their work. We also were happy with the 1h plenary discussions, which were very lively.


Scientific developments and Aha-insights

The scientific highlights of the workshop were summarized by Chris Ormel at the close of the meeting. These new realizations include: the realization that initial conditions matter for disk evolution, the importance of icelines in explaining ALMA observations and triggering planet-formation instabilities, the connection between super-Earth planets and solar-system planets, the importance of constraining planet formation theories in binary systems. There is plenty of research to do.


To the best of our knowledge, this has been the first dedicated meeting on planet formation topics in the Netherlands. For some of the participants this had been their first visit to the Netherlands. Since it has become clear in recent years that disk science and planet formation science are intimately connected, this is a welcome development for the emergent exoplanet research in the Netherlands.


In summary, we look back on an exhaustive but very successful week!
