Query: A Deep Search for Binary TNOs   The Latitude Density Search utilized Hyper Suprime-Cam on Subaru Telescope to
discover 60 moving objects in the outer Solar System, 54 of which have
semi-major axes beyond 30 AU. The images were acquired in exceptional seeing
(0.4") and reached a detection limit of m_r~=25.2. The two night arcs were used
to calculate orbits which are poorly constrained, however, the distance and
inclination are the parameters best constrained by short arcs and a reasonable
determination can be made of which objects are cold classical TNOs and which
are dynamically excited. We identify 10 objects as likely cold classical
objects. We searched all of the detections for binary sources using a trailed
Point Spread Function subtraction method, and identified one binary object with
a separation of 0.34" and a secondary with 17% the brightness of the primary
(2.0 magnitudes fainter). This is the brightest TNO in the sample, the
previously known object 471165 (2010 HE79), which has a dynamically excited
orbit. Because of the excellent seeing, this search was sensitive to binaries
with 0.34" separation and a brightness of >=50% the primary brightness for 7
objects, including one cold classical. This gives an intrinsic binary fraction
of ~17% (1 of 6) for the dynamically excited objects within our detection
limits. The trailed point spread function subtraction method to identify
binaries, fit the two components, and determine the sensitivity limits, used in
the Latitude Density Search is a useful tool that could be more broadly applied
to identify binary TNOs and track known binary TNO orbits.
