A new all-sky catalog of stars with large proper motions

Abstract

A new all-sky catalog of stars with proper motions μ > 0.15″ yr-1 is presented. The catalog is largely a product of the SUPERBLINK survey, a data-mining initiative in which the entire Digitized Sky Surveys are searched for moving stellar sources. Findings from earlier proper motions surveys are also incorporated. The new all-sky catalog supersedes the great historic proper motion catalogs assembled by W. J. Luyten (LHS, NLTT), and provides a virtually complete > 98% census of high proper motion stars down to magnitude R = 19. © 2008 Copyright International Astronomical Union.
