VizieR Online Data Catalog: Membership in the Cepheus association (Klutsch+, 2020)
Abstract
We present the results of a spectroscopic survey of optical counterparts of X-ray sources in the Cepheus region (near the North Celestial pole) aimed at discovering further young objects around the four comoving stars reported by us in Paper II (Guillout et al., 2010A&A...520A..94G).
table 1 summarizes the optical and infrared names of each X-ray source, along with those appearing in Simbad and some main parameters coming from the literature. table 3 reports the radial velocity of all the stars, including the measurements for each component of a spectroscopic system, along with the rotational velocity,atmospheric parameters, and lithium equivalent widths derived for the targets identified as single stars or SB1 systems. table 4 provides the astrometry in Gaia DR2, the Galactic positions, and the extinction estimate of our targets, as well as the space velocities of those identified as single stars. table 5 lists all the sources that are comoving with one of our targets.
