Strömgren photometric metallicity of the Small Magellanic Cloud stars using Gaia DR3-XP spectra
Abinaya O. Omkumar, Smitha Subramanian, Maria-Rosa L. Cioni +1
Observational studies have identified several sub-structures in different regions of the Magellanic Clouds, the nearest pair of interacting dwarf satellites of the Milky Way. By st…
A Gaia study of the Hyades open cluster
Stella Reino, Jos de Bruijne, Eleonora Zari +2
We present a study of the membership of the Hyades open cluster, derive kinematically-modelled parallaxes of its members, and study the colour-absolute magnitude diagram of the clu…
The intricate Galaxy disk: velocity asymmetries in Gaia-TGAS
T. Antoja, J. de Bruijne, F. Figueras +3
We use the Gaia-TGAS data to compare the transverse velocities in Galactic longitude (coming from proper motions and parallaxes) in the Milky Way disk for negative and positive lon…
Gaia Data Release 1: Astrometry - one billion positions, two million proper motions and parallaxes
L. Lindegren, U. Lammers, U. Bastian +80
Gaia Data Release 1 (Gaia DR1) contains astrometric results for more than 1 billion stars brighter than magnitude 20.7 based on observations collected by the Gaia satellite during…
Kinematics of symmetric Galactic longitudes to probe the spiral arms of the Milky Way with Gaia
T. Antoja, S. Roca-Fabrega, J. de Bruijne +1
We model the effects of the spiral arms of the Milky Way on the disk stellar kinematics in the Gaia observable space. We also estimate the Gaia capabilities of detecting the predic…
