Abstract

High proper motion stars probe several extreme stellar populations, including nearby objects, Galactic halo stars, and hypervelocity stars. Extending the search for high proper motion stars, to faint limits can increase their numbers and help to identify interesting targets. We conduct a search for faint (r_SDSS > 19.5 mag) high proper motion stars ( 200 mas yr⁻¹) by comparing the Sloan Digital Sky Survey (SDSS) - Data Release (DR) 10 catalogue to the Pan-STARRS1-DR1 stacked image catalogue. Our main selection criterion is stars that moved >1 . 5 and up to 7 arcsec between the SDSS and PS1 epochs. We identify 2923 high proper motion stars, of which 826 do not have proper motion in the GAIA-DR2 catalogue and 565 are not listed in the GAIA-DR2 catalogue.
