Diversity of extrasolar planetesimals

Planetesimals and pebbles are fundamental building blocks for solar system planets and Exoplanets alike. In this talk I review our latest models on pebble evolution and planetesimal formation. We find that the gas mass of the circumstellar disk has a much stronger influence on pebble and planetesimal sizes than the stellar type of the host star.
