A spectroscopy study of nearby late-type stars, possible members of stellar kinematic groups. Maldonado J., Martinez-Arnaiz R.M., Eiroa C., Montes D., Montesinos B. <Astron. Astrophys. 521, A12 (2010)> =2010A&A...521A..12M

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), Beavers et al. (1979PASP...91..698B), and Udry et al. (1999ASPC..185..383U, 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. File Summary:
