Abstract:
We present the results of a proper motion study aiming at providing
further evidence on the origin of the proposed stellar members of the
Chamaeleon I and II clouds and to identify interlopers from the
foreground young clusters ε Cha and η Cha. We compiled lists
of spectroscopically confirmed members of the four associations, and
of background objects in the same line of sight. Using Virtual
Observatory tools, we cross-matched these lists with the UCAC3 (Cat.
I/315) catalogue to get proper motions for the objects. In the vector
point diagram, we identified the different moving groups, and used
this information to study the membership of proposed candidate members
of the associations from the literature. For those objects with
available radial velocities, we computed their Galactic space
velocities. We compiled photometry from public data archives and
from the literature for the Cha I and II objects. We looked for
correlations between the properties of the objects and their proper
motions.
