The Liverpool-Edinburgh high proper motion survey

Abstract

Abstract. We present a catalogue of 6206 stars which have proper motions exceeding 0.18 yr −1 with an R-band faint magnitude limit of 19.5 mag. This catalogue has been produced using SuperCOSMOS digitized R-band ESO and UK Schmidt Plates in 131 Schmidt fields covering more than 3 000 square degrees (>7.5% of the whole sky) at the South Galactic Cap. The survey is ≥90% complete within the nominal limits of the Luyten Two Tenths Catalogue of m R ≤ 18.5 mag and 0.2 ≤ µ ≤ 2.5 yr −1 , and is ≥80% complete for m R ≤ 19.5 mag and µ ≤ 2.5 yr −1 .

The Solar Neighborhood. XLII. Parallax Results from the CTIOPI 0.9 m Program—Identifying New Nearby Subdwarfs Using Tangential Velocities and Locations on the H–R Diagram

“…Thus, to understand the nature of the metal-poor stars that formed early in the history of the Galaxy, it is important to identify more nearby subdwarfs so that the most basic stellar parameters of masses and radii can be determined. In order to reveal nearby subdwarfs, the Cerro Tololo Interamerican Observatory Parallax Investigation (CTIOPI) carried out by RECONS (REsearch Consortium On Nearby Stars) 8 has targeted subdwarf candidates with high proper motions extracted from various catalogs and surveys (Giclas et al 1971;Giclas 1979;Luyten 1979;Pokorny et al 2003;Hambly et al 2004;Scholz et al 2004a;Deacon et al 2005;Lépine & Shara 2005;Gizis et al 2011). Here, we present the first parallaxes for 37 stellar systems selected from these surveys and revised parallaxes for 14 additional systems.…”

New High Proper Motion Stars from the Digitized Sky Survey. II. Northern Stars with 0."5 yr-1< < 2."0 yr-1at High Galactic Latitudes

“…Most of the new, deep proper motion surveys are being conducted in the southern sky. These include the Scholz et al (2000) survey, the Calán-ESO proper-motion survey (Ruiz et al 2001), and the Liverpool-Edinburgh proper-motion survey (Pokorny, Jones, & Hambly 2003). These surveys are all based on the analysis of photographic plate material obtained from the 1970s to the 1990s (the United Kingdom Schmidt Telescope survey and the ESO-Schmidt survey).…”

Southern infrared proper motion survey. II. A sample of low mass stars with $\mathsf{\mu \geq 0.1''/ {yr}}$

“…Of those which go to lower limits two, Ruiz et al (2001) and Wroblewski & Costa (2001), are limited in the areas of sky they cover. This leaves only three surveys which cover the majority of the southern hemisphere to lower proper motion limits comparable to ours: Luyten's New Luyten Two Tenths catalogue (NLTT, Luyten 1979b), Pokorny et al's (2003) Liverpool-Edinburgh High Proper Motion survey (LEHPM) and Finch et al (2007). Both Luyten and Pokorny have lower proper motion limits of 0.2 /yr, however Luyten's survey is incomplete below δ = −30…”
