|Space astrometry at Lund Observatory
During more than two decades, researchers at Lund Observatory have participated
in the ESA space astrometry mission
first in the planning and execution of the science data reductions, and
then in the utilization of the space data in stellar and galactic research.
Since 1995 we are strongly involved in the development of galactic census
project Gaia, a cornerstone
mission within the ESA science programme, targeted for launch in December 2013.
The space astrometry group is led by Lennart Lindegren, who is also a member of the
Gaia Science Team
(GST) appointed by the European Space Agency. Within the
Gaia Data Processing and Analysis Consortium
the other senior member of the group, David Hobbs, is the scientific
secretary of Coordination Unit 3 (CU3), in which the core processing of
the Gaia data is being developed. PhD students Daniel Michalik and
Rajesh Kumar Bachchan work on specific applications which are not part
of the DPAC development. Hobbs and Lindegren collaborate with specialists at ESAC to implement the astrometric core solution, the so-called Astrometric
Global Iterative Solution (AGIS). Other associated and formal members of the Lund space astrometry group are listed below.
This research programme is supported since
many years by the Swedish National Space
Board (current project title: Astrophysical space research using Gaia),
and during 1998-2003 by the Swedish
Research Council (Stellar multiplicity: Origin and
evolution; Statistics and dynamics).
