IAU Symposium 330 in Nice, France, 24-28 April 2017: First announcement


We are pleased to announce the opening of the registration for the IAU
symposium 330 - Astrometry and Astrophysics in the Gaia sky, to be held
in Nice (France), from 24-28th April 2017.

The goal of this IAU symposium is to ensure the world-wide sharing of
the Gaia mission results, foster international collaborations and
discussions that will enhance the Gaia scientific return. This symposium
will mark the first step of the Gaia revolution in astrometry, our
understanding of the Milky Way galaxy, stellar physics and the Solar
system bodies. The astrometry and reference frames science will be one
of the conference highlights. The Gaia DR1 is indeed confirmed for the
end of summer 2016. It will include the five-parameter astrometric
solution - positions, parallaxes, and proper motions - for 2.5 million
stars in common between the Tycho-2 Catalogue and Gaia (TGAS).

All these topics will be at the heart of the interdisciplinary
scientific discussions of the symposium. We indeed hope to bring
together the diverse scientific communities that will be impacted by the
Gaia data. The conference will also be a tribute to Francois Mignard,
expert in astrometry and reference frames, and chair of the Gaia Data
Processing and Analysis Consortium since its formation and until the end
of 2012.

Please visit the IAUS 330 website for more information:

The deadline for abstract submission and early registration are
December 4, 2016 and January 10, 2017, respectively.

We are looking forward to seeing you in Nice in April 2017!

Alejandra Recio-Blanco, Anthony Brown and Timo Prusti (for the SOC)
Patrick de Laverny (for the LOC)
