GAIA @ ROB
The participation of the ROB in the preparation of Gaia started as early as 1998 in various working groups, and continued after DPAC definition in CU4, CU6, CU7, and CU8.
The members of the Gaia ROB have different domains of expertise that encompass the physics and dynamics of intermediate mass to massive stars (O, Be, B[e], A stars), of variable and multiple stars, and asteroids. Our contributions imply work package management and software development.
In CU8, we are dealing with the identification and classification of peculiar and emission-line stars. Our tasks include the computation and delivery of synthetic spectra computed with different codes, the data mining in existing catalogues, the observation of peculiar stars and the subsequent data reduction as part of our GBOG activities.
For CU7, our staff is working on variability characterization and is conceiving algorithms enabling the search and determination of periods of variable signals.
We are also involved in specific objects studies. As members of CU6, we are developing and proposing various approaches allowing the extraction of single and multiple stars radial velocities and projected rotation velocities from single transit RVS data.
And in CU4, our team is taking care of the astrometric reduction of Solar system objects (SSOs). Our efforts and participation to the Gaia DPAC are supported by the Belgian ESA PRODEX program.
