Photometric parallaxes of Southern high proper motion stars. I.

Costa E.; Mendez, RA

Abstract

Photometric distances derived from VRI photometry arc given for 44 high proper motion stars from the Cerro El Roble proper motion surveys of Wroblewski & Torres and Wroblewski & Costa. The observations were carried out with the main purpose of estimating the distance of selected members of the above survey that are likely to be nearby. We have discovered 13 stars closer than 25 pc, the classical limit of the Catalogs of Nearby Stars (see e.g. Gliese & Jahreiß 1991) und the NASA/NSF NStars Project. Those stars of the sample whose photometric distances are less than ?25 pc, or have proper motions in excess of 0.50 arcsec/year, are either currently being targeted by the Cerro Tololo Parallax Investigation (CTIOPI) or will be targets of a forthcoming expansion of this survey.
