Abstract:
This is the first paper of a series aimed at studying the properties
of late-type members of young stellar kinematic groups. We concentrate
our study on classical young moving groups such as the Local
Association (Pleiades moving group, 2-150Myr), IC 2391 supercluster
(35Myr), Ursa Major group (Sirius supercluster, 300Myr), and Hyades
supercluster (600Myr), as well as on recently identified groups such
as the Castor moving group (200Myr). In this paper we compile a
preliminary list of single late-type possible members of some of these
young stellar kinematic groups. Stars are selected from previously
established members of stellar kinematic groups based on photometric
and kinematic properties as well as from candidates based on other
criteria such as their level of chromospheric activity, rotation rate
and lithium abundance. Precise measurements of proper motions and
parallaxes taken from the Hipparcos Catalogue, as well as from the
Tycho-2 Catalogue, and published radial velocity measurements are used
to calculate the Galactic space motions (U, V, W) and to apply Eggen's
kinematic criteria in order to determine the membership of the
selected stars to the different groups.

Note (G1): Group designations:
Castor: Castor Moving Group
HS: Hyades supercluster
IC 2391: IC 2391 supercluster
LA: Local Association
UMa: Ursa Mayor group
YD: Other Young Disk stars
Note (G2): Predicted velocities:
VT = 4.74*{mu}/({pi}*sin{lambda}) rhoc = VT*cos{lambda},
where {mu} is the component of the absolute proper motion in the
direction of the convergent point and perpendicular to it, {pi} is
the trigonometric parallax and {lambda} the angular distance between
the star and the convergent point.
