Abstract:
The UKIDSS Galactic Plane Survey (GPS) began in 2005 as a seven year
effort to survey ∼1800deg2 of the northern Galactic plane in the J,
H, and K passbands. The survey included a second epoch of K-band data,
with a baseline of two to eight years, for the purpose of
investigating variability and measuring proper motions. We have
calculated proper motions for 167 million sources in a 900deg2 area
located at l>60° in order to search for new high proper motion
objects. Visual inspection has verified 617 high proper motion sources
(>200mas/yr) down to K=17, of which 153 are new discoveries. Among
these, we have a new spectroscopically confirmed T5 dwarf, an
additional T dwarf with estimated type T6, 13 new L dwarf candidates,
and two new common proper motion systems containing ultracool dwarf
candidates. We provide improved proper motions for an additional 12
high proper motion stars that were independently discovered in the
WISE data set during the course of this investigation.
Description:
Astrometric and photometric information for 153 high proper motion
sources identified for the first time by this search.
