The ALADIN Interactive Sky Atlas
Francois Bonnarel, Pierre Fernique, Olivier Bienayme +6
The Aladin interactive sky atlas, developed at CDS, is a service providing simultaneous access to digitized images of the sky, astronomical catalogues, and databases. The driving m…
The CDS information hub
Francoise Genova, Daniel Egret, Olivier Bienayme +8
The Centre de Donnees astronomiques de Strasbourg (CDS) provides homogeneous access to heterogeneous information of various origins: information about astronomical objects in Simba…
The local stellar velocity distribution of the Galaxy. Galactic structure and potential
O. Bienaymé
The velocity distribution of neighbouring stars is deduced from the Hipparcos proper motions. We have used a classical Schwarzschild decomposition and also developed a dynamical mo…
Structure and kinematical properties of the Galaxy at intermediate galactic latitudes
Devendra Ojha, Olivier Bienayme, Annie Robin +2
We have carried out a sample survey in UBVR photometry and proper motions in different directions in the Galaxy, as part of an investigation of galactic structure and evolution. Th…
Astrometric Plate Reduction with Orthogonal Functions and Milli-Arcseconds Accuracy in Deep Proper Motion Surveys
Devendra Ojha, Olivier Bienayme
We have been doing a sample survey in UBV photometry and proper motions as part of an investigation of galactic structure and evolution. The programme is based on Schmidt plates (f…
The Asymmetric Drift of the Thick Disk Population
Devendra Ojha, Annie C. Robin, Olivier Bienayme
We investigate the kinematics of the intermediate population using the photometric and astrometric sample surveys towards two opposite directions (galactic centre and anticentre) a…
