Abstract:
The Lupus dark cloud complex is a well-known, nearby low-mass
star-forming region, probably associated with the Gould Belt. In
recent years, the number of stellar and substellar Lupus candidate
members has been remarkably increased thanks to the Cores to Disks
(c2d) Spitzer Legacy Program and other studies. However, most of these
newly discovered objects still lack confirmation that they belong to
the dark clouds.
By using available kinematical information, we test the membership of
the new Lupus candidate members proposed by the c2d program and by a
complementary optical survey. We also investigate the relationship
between the proper motions and other properties of the objects, in
order to get some clues about their formation and early evolution.
We compiled a list of members and possible members of Lupus 1, 3, and
4, together with all available information on their spectral types,
disks, and physical parameters. Using Virtual Observatory tools, we
cross-matched this list with the available astrometric catalogues to
get proper motions for our objects. Our final sample contains sources
with magnitudes I<16mag and estimated masses ≳0.1M☉.
