Extract

The HR 1614 moving group of stars (Eggen 1978a) is one of a number of such groups identified by Eggen from amongst the disk population of the Galaxy (see e.g. Eggen 1969). The group was selected from a sample of 44 field stars south of + 30° declination, with right ascensions mainly > 12h and <2h, and with motions similar to that of the star HR 1614, which has a velocity of (U, V) = (−1, −58) km s−1, where U and V are the components of space motion in the direction of the galactic anticentre and galactic rotation respectively, measured relative to the Sun. The colours of these 44 stars, when plotted in a (b-y, R-I) diagram, were such that 26 of them had an excess blanketing of ~ 0.03 in b-y, measured with respect to the Hyades group. This excess blanketing was consequently chosen to be a criterion for group membership.
