Abstract:
Nearby late-type stars are excellent targets for seeking young objects
in stellar associations and moving groups. The origin of these
structures is still misunderstood, and lists of moving group members
often change with time and also from author to author. Most members
of these groups have been identified by means of kinematic criteria,
leading to an important contamination of previous lists by old field
stars. We attempt to identify unambiguous moving group members among a
sample of nearby-late type stars by studying their kinematics, lithium
abundance, chromospheric activity, and other age-related properties.
Description:
File table1 contains the name of the observed stars, coordinates,
astrometric data, radial velocities and notes. Parallaxes are taken
from van Leeuwen (2007, Cat. I/311) and proper motions from Tycho-2
(2000, Cat. I/259).
Radial velocities were derived from high-resolution spectra taken with
the FOCES spectrograph at the Calar Alto observatory (Almeria, Spain)
and the SARG spectrograph at the Telescopio Nazionale Galileo in La
Palma (Canary Islands, Spain). Additional spectra from the public
library "S4N" (Allende Prieto et al., 2004, Cat. J/A+A/420/183) were
also used. Radial velocities were measured by cross-correlating the
spectra of our programme stars with spectra of radial velocity
standard stars taken from Barnes et al. (1986PASP...98..223B 1986PASP...98..223B), Beavers
et al. (1979PASP...91..698B 1979PASP...91..698B), and Udry et al. (1999ASPC..185..383U 1999ASPC..185..383U,
1999ASPC..185..367U 1999ASPC..185..367U). For known spectroscopic binaries the radial
velocity of the centre of mass of the system is given. These values
are from Pourbaix et al. (Cat. B/sb9/) or Eker et al. (2008, Cat.
V/128 ). Previous radial velocities reported in the literature are
also given for comparison.
