Scientific paper

We present the results of a search for nearby low mass stars and white dwarfs among proper motion stars identified in the full SUPERBLINK all-sky survey. Over 1 million stars with low proper motions (40 mas/yr < μ < 150 mas/yr), are being sifted through in search of nearby objects with relatively small transverse velocities, which have been much overlooked in the past. We show that our survey will considerably extend the census of low-mass stars and white dwarfs within 100 parsecs of the Sun. In particular, this survey will identify most of the still elusive, slow-moving stars in the Solar Neighborhood (d<33; pc), bringing the local stellar census to near completion. This research has been supported by NSF grant AST 0607757, and by the NSF Research Experience for Undergraduates program.
