Faint objects in motion: the new frontier of high precision astrometry
Fabien Malbet, Céline Boehm, Alberto Krone-Martins +83
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
A census of Oph candidate members from Gaia DR2
H. Cánovas, C. Cantero, L. Cieza +6
The Ophiuchus cloud complex is one of the best laboratories to study the earlier stages of the stellar and protoplanetary disc evolution. The wealth of accurate astrometric measure…
The co-existence of hot and cold gas in debris discs
I. Rebollido, C. Eiroa, B. Montesinos +19
Debris discs have often been described as gas-poor discs as the gas-to-dust ratio is expected to be considerably lower than in primordial,protoplanetary discs. However, recent obse…
Theia: Faint objects in motion or the new astrometry frontier
The Theia Collaboration, Celine Boehm, Alberto Krone-Martins +96
In the context of the ESA M5 (medium mission) call we proposed a new satellite mission, Theia, based on relative astrometry and extreme precision to study the motion of very faint…
The Gaia Archive
Alcione Mora, Juan González-Núñez, Deborah Baines +5
The Archive is the main Gaia data distribution hub. The contents of DR1 are briefly reviewed and the data structures discussed. The system architecture, based on Virtual Observator…
Gaia: focus, straylight and basic angle
A. Mora, M. Biermann, A. Bombrun +17
The Gaia all-sky astrometric survey is challenged by several issues affecting the spacecraft stability. Amongst them, we find the focus evolution, straylight and basic angle variat…
