Tìtulo:
 From dust to planetesimals - constraints from 25 years of laboratory
experiments

AUTHOR:
Jürgen Blum, IGeP, TU Braunschweig, Germany

ABSTRACT:
Dust growth in protoplanetary disks has been observed and its outcome  
are eventually
planetary bodies. However, the growth from microscopically small dust  
particles to
planetesimal  sizes is not straightforward, but obstructed by  
processes like bouncing,
fragmentation or erosion of dust aggregates, which  have  been   
observed in laboratory
experiments. After 25 years of laboratory work on dust  coagulation  
and modeling of the
planetesimal-formation process, there are a few avenues left along  
which planetesimals
may form. I will review the  most important and the latest laboratory  
results and will
comment on the plausibility of the main formation scenarios of planetesimals.
