Abstract:
We search for stars with proper motions in a set of deep Subaru
images, covering about 0.48 square degrees to a depth of i'~=26, taken
over a span of five and a half years. We follow the methods described
in Richmond et al. (2009, Cat. J/PASJ/61/97) to reduce and analyze this
dataset. We present a sample of 69 stars with motions of high
significance, and discuss briefly the populations from which they are
likely drawn. Based on photometry and motions alone, we expect that 14
of the candidates may be white dwarfs. Our candidate with the largest
proper motion is surprisingly faint and likely to prove interesting:
its colors and motions suggest that it might be an M dwarf moving at
over 500km/s or an L dwarf in the halo.
Description:
The Subaru/XMM-Newton Deep Survey (SXDS) involves sensitive
measurements across a wide range of wavelengths over a region of about
1.3 square degrees.
We analyze a subset of the optical images taken with the Subaru
8.2-meter telescope and Suprime-Cam camera. The regions in the
southern (SXDS-S) and eastern (SXDS-E) sections of the survey were
observed at least 11 times over the period 2002 September to 2008
January. Note that data taken on 2002 September 29 and September 30
were combined to form a single composite image.
