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.
