Title: Continued Kinematic and Photometric Investigations of Hierarchical Solar-Type Multiple Star Systems,
Abstract: We observed 15 of the solar-type binaries within 67 pc of the Sun previously
observed by the Robo-AO system in the visible, with the PHARO near-IR camera
and the PALM-3000 adaptive optics system on the 5 m Hale telescope. The
physical status of the binaries is confirmed through common proper motion and
detection of orbital motion. In the process we detected a new candidate
companion to HIP 95309. We also resolved the primary of HIP 110626 into a close
binary making that system a triple. These detections increase the completeness
of the multiplicity survey of the solar-type stars within 67 pc of the Sun.
Combining our observations of HIP 103455 with archival astrometric measurements
and RV measurements, we are able to compute the first orbit of HIP 103455
showing that the binary has a 68 yr period. We place the components on a
color-magnitude diagram and discuss each multiple system individually.
