New High Proper Motion Stars from the Digitized Sky Survey. II. Northern Stars with 0.5 < µ < 2.0 ′ ′ yr −1 at High Galactic Latitudes. 1
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−...
متن کاملNew High Proper Motion Stars from the Digitized Sky Survey. Iv. Completion of the Southern Survey and 170 Additional Stars with Μ > 0.45′′yr−1.1
Completion of the SUPERBLINK proper motion survey in the southern celestial hemisphere has turned up 170 new stars with proper motion 0.45′′yr−1 < μ < 2.0′′yr−1. This fourth and final installment completes the all-sky, data-mining of the Digitized Sky Surveys for stars with large proper motions. The areas investigated in this final installment comprise 11,600 square degrees in the declination r...
متن کاملOGLE-II High Proper Motion Stars towards the Galactic centre
The photometry data base of the second phase of the OGLE microlensing experiment, OGLE-II, is a rich source of information about the kinematics and structure of the Galaxy. In this work we use the OGLE-II proper motion catalogue to identify candidate stars which have high proper motions. 521 stars with proper motion μ > 50 mas yr in the OGLE-II proper motion catalogue (Sumi et al. 2004) were cr...
متن کاملSpectroscopy of New High Proper Motion Stars in the Northern Sky . I .
We define an enhanced spectral classification scheme for M dwarf stars, and use it to derive spectral classification of 104 northern stars with proper motions larger than 0.5 yr which we discovered in a survey of high proper motion stars at low galactic latitudes. The final tally is as follows: 54 M dwarfs, 25 sdK and sdM subdwarfs, 14 esdK and esdM extreme subdwarfs, and 11 DA and DC white dwa...
متن کاملSpectroscopy of New High Proper Motion Stars in the Northern Sky . I . New Nearby Stars , New High Velocity Stars , and an Enhanced Classification Scheme for
We present spectral classification of 105 northern stars with proper motions larger than 0.5 yr, which were recently discovered by us in a survey of high proper motion stars at low galactic latitudes. The final tally is as follows: 54 M dwarfs, 25 sdK and sdM subdwarfs, 14 esdK and esdM extreme subdwarfs, and 12 DA and DC white dwarfs. Among the most interesting cases, we find one star to be th...
