The Solar Neighborhood. 31. Discovery of an Unusual Red+White Dwarf Binary at approx. 25 pc via Astrometry and UV Imaging

Abstract

We report the discovery of a nearby M5.0V dwarf at 24.6 pc, SCR 1848 6855, that is orbited by an unusual companion causing an astrometric perturbation of more than 200 mas. This is by far the largest perturbation found to date among more than 700 targets observed during our long-term astrometry/photometry program at the CTIO 0.9 m telescope.
