Title: How did protoplanets form out of dust?

Abstract: Have you ever wondered why the dust clumps that have been accumulating for months under your sofa are never bigger than a few cm? Probably not. But let me tell you about it anyway, because it also happens to be one of the most challenging question in planetary science. In fact, we know dust and gas dominated the protoplanetary disk, and we know that now there are planets and asteroids. Yet, dust clumps can’t grow above a threshold size; intriguing. In this presentation, I’ll talk about a turbulent mechanism that could explain how protoplanets formed out of dust.

 - The Whizkey Seminar is very informal. (Relevant) interruptions and side-tracking for better understanding, clarification, and questions are welcome and even encouraged.

 - There is no “official” theme for the talks, however, there is one (flexible) requirement: get out of your comfort zone! Have you been meaning to delve into a review article or a series of papers that aren’t directly relevant to your work but you found fascinating? Have you learned or want to learn a cool applied math method? These are good examples of subjects for Whizkey Seminars. The point here is to learn, understand, and be curious in an active way, and also go out of your comfort zone a bit to learn something new which might not be immediately useful.
