Structure, kinematics, and ages of the young stellar populations in the Orion region

E. Zari, A. G. A. Brown, P. T. de Zeeuw

We present a study of the three dimensional structure, kinematics, and age distribution of the Orion OB association, based on the second data release of the Gaia satellite (Gaia DR…

3D mapping of young stars in the solar neighbourhood with Gaia DR2

E. Zari, H. Hashemi, A. G. A. Brown +2

We study the three dimensional arrangement of young stars in the solar neighbourhood using the second release of the Gaia mission (Gaia DR2) and we provide a new, original view of…

A Hipparcos census of the nearby OB associations

P. T. de Zeeuw, R. Hoogerwerf, J. H. J. de Bruijne +2

A comprehensive census of the stellar content of the nearby OB associations is presented, based on Hipparcos positions, proper motions, and parallaxes. Moving groups are identified…

The Hyades: distance, structure, dynamics, and age

M. A. C. Perryman, A. G. A. Brown, Y. Lebreton +7

We use absolute trigonometric parallaxes from the Hipparcos Catalogue to determine individual distances to members of the Hyades cluster, from which the 3-dimensional structure of…
