Classifying Luyten Stars Using An Optical-Infrared Reduced Proper Motion Diagram
نویسنده
چکیده
We present a V − J reduced proper motion (RPM) diagram for stars in the New Luyten Two-Tenths (NLTT) catalog. In sharp contrast to the RPM diagram based on the original NLTT data, this optical-infrared RPM diagram shows distinct tracks for white dwarfs, subdwarfs, and main-sequence stars. It thereby permits the identification of white-dwarf and subdwarf candidates that have a high probability of being genuine. Subject headings: astrometry – subdwarfs – white dwarfs

We complete construction of a catalog containing improved astrometry and new optical/infrared photometry for the vast majority of NLTT stars lying in the overlap of regions covered by POSS I and by the second incremental 2MASS release, approximately 44% of the sky. The epoch 2000 positions are typically accurate to 130 mas, the proper motions to 5.5 mas yr −1 , and the V − J colors to 0.25 mag....
متن کاملSpitzer Studies of Ultracool Subdwarfs : Metal - poor Late - type M , L and T
Recent discoveries from red optical proper motion and wide-field near-infrared surveys have uncovered a new population of ultracool subdwarfs, metal-poor stars and brown dwarfs extending into the late-type M, L and possibly T spectral classes. These objects are among the first low-mass stars and brown dwarfs formed in the Galaxy, and are valuable tracers of metallicity effects in low-temperatur...

متن کاملMeeting the Cool Neighbours, II: Photometry of southern NLTT stars
We present BVRI photometry of 180 bright, southern nearby-star candidates. The stars were selected from the New Luyten Two-Tenths proper motion catalogue based on optical/infrared colours, constructed by combining Luytens’s mr estimates with nearinfrared photometry from the 2-Micron All Sky Survey. Photometric parallaxes derived from (V-KS), (V-I) and (I-J) colours, combined with the limited av...

In a continuation of our systematic search for high proper motion stars in the Digitized Sky Survey, we have completed the analysis of northern sky fields at galactic latitudes above 25 degrees. With the help of our SUPERBLINK software, a powerful automated blink comparator developed by us, we have identified 1146 stars in the magnitude range 8 < r < 20 with proper motions 0.500 < μ < 2.000 yr−...
