J/A+A/421/643       New nearby stars in the LEHPMS                (Reyle+, 2004)

New nearby stars in the Liverpool-Edinburgh high proper motion survey selected by DENIS photometry. Reyle C., Robin A.C. <Astron. Astrophys. 421, 643 (2004)> =2004A&A...421..643R
ADC_Keywords: Stars, nearby ; Proper motions ; Photometry, infrared Keywords: Galaxy: solar neighbourhood - stars: lates type - stars: white dwarfs Abstract: We present a systematic search for new neighbourhood stars among the Liverpool-Edinburgh high proper motion survey which we cross-identified with the DENIS survey. Their high proper motions ensure that they are not giant stars. The distances are estimated using DENIS photometry and we found that 100 stars probably lie within 25 parsecs from the Sun. They are mostly M-dwarfs, and 10 are probably white dwarfs. This is the first distance estimate for 84 stars among them. 10 stars are estimated to be closer than 15 parsecs. In addition, one star, DENIS J2343155-241047, could also lie within 15pc if it belongs to the halo. Description: Proper motions, photometric parameters, and distances for 100 nearby star candidates closer than 25pc. Stars are selected in the Liverpool-Edinburgh high proper motion by DENIS photometry. The DENIS I-J colour index is used for determining the distance. File Summary:
