Planetesimal formation

Workshop theme

The enormous diversity of the over 300 extra-solar planets discovered to date challenges our understanding of the planet formation process. A crucial first stage is the formation of kilometre and larger sized planetesimals from microscopic interstellar dust grains in protoplanetary discs. This workshop, organised as part of the four-month long programme "The Dynamics of Discs and Planets", will address some of the key issues associated with the formation of planetesimals in discs.

Specific themes that will be discussed include:

the coupled dynamics of gas and dust in protoplanetary discs
the growth of grains
gravitational instabilities in discs

Both the theory and observational constraints will be reviewed. Only a few review-style talks will be given each day, leaving plenty of time for open discussion. Poster presentations by all participants are strongly encouraged.
