Abstract

We present proper motion measurements of pre-main sequence (PMS) stars associated with major star-forming regions of the southern hemisphere (Chamaeleon, Lupus, Upper Scorpius - Ophiuchus, Corona Australis), situated in the galactic longitude range l=290{deg} to l=360{deg}. A list of PMS stars as complete as possible was established based on the Herbig and Bell (1988LicOB1111....1H) catalogue and many new catalogues like the PDS survey, the catalogue of Herbig Ae/Be stars by The et al. (1994A&AS..104..315T), X-rays surveys, etc. The measurements made use of public material (mainly AC2000 and USNO-A2.0 catalogues) as well as scans of SERC-J Schmidt plates with the MAMA measuring machine (Paris) and Valinhos CCD meridian circle observations (Brazil). We derived proper motions for 213 stars, with an accuracy of 5 to 10mas/yr depending mainly on the difference of epochs between the position sources. The main characteristics of the sample are discussed. We show that systematic motions of groups of stars exist, which are not explained by the reflex solar motion.
