Dust is present almost everywhere in the Universe, out of our galaxy and in the Solar system. Everyone of us researchers sees them under a different angle. Dust extinction has in fact become one of the most widely used tracer for the gas mass. Its spectral emission distribution help us assess the temperature in many environments. The light scattered from the dust (coreshine) now tells us more about the dust grain geometry. Recent dust polarization measurements by Planck have allowed us to map the projection of the magnetic fields on the whole sky. The grains are a key dynamical actor in many ways: they control the formation of the first adiabatic core prior to the formation of a star, they entrain stellar winds, the inertia of the charged grains modifies the dynamics of magnetised shocks, charged grains allow the magnetorotational instability to impact planet formation in proto-planetary discs. Grains even come to Earth, evaporated from comets, and can be analysed, or can be mimicked in laboratory to understand their intrinsic properties.  Finally, chemistry on dust surfaces may be one of the master keys to understand the molecular complexity (even perhaps the origin of pre-biotic chemistry) and this has generated a wealth of laboratory experiments and theoretical developments.

This workshop is an opportunity for everyone of us to exchange our respective views on each facet of the grains which we find useful in our own research domain. We hope it will foster fertile discussions and generate new collaborations.

Lunch will be served for registered persons.
