We present speckle interferometry observations of 47 composite spectrum stars obtained between 1993 and 1998 at the Pic du Midi Observatory with the PISCO speckle camera. 76% of over 150 independent 10-min sequences of observations led to a companion detection. Binary component angular separations ranged from 0.05 ′′ to 1.2 ′′ . We also obtained a series of 23 measurements of an additional 9 close binaries. PISCO observations confirm, for the first time since their discovery, the duplicity of HD 29104 (L 4), HD 83808 (WGT 1Aa), HD 183912 Aa' (BON Ap), and HD 156729 (HR 6436). Discovered as double by Hipparcos, the particularly difficult to resolve HD 156729 was observed despite the large magnitude difference, ∆m = 4.2, between its two components.

“…HIP 3795 (HD 4655 = WDS 00487+1841) is a quadruple system. The inner AB pair, BU 495, has an orbit with a 143.6±4.0 yr period (Scardia et al 2000).…”

Observations of Hierarchical Solar-Type Multiple Star Systems

et al. 2015

Twenty multiple stellar systems with solar-type primaries were observed at high angular resolution using the PALM-3000 adaptive optics system at the 5 m Hale telescope. The goal was to complement the knowledge of hierarchical multiplicity in the solar neighborhood by confirming recent discoveries by the visible Robo-AO system with new near-infrared observations with PALM-3000. The physical status of most, but not all, of the new pairs is confirmed by photometry in the Ks band and new positional measurements. In addition, we resolved for the first time five close sub-systems: the known astrometric binary in HIP 17129AB, companions to the primaries of HIP 33555, and HIP 118213, and the companions to the secondaries in HIP 25300 and HIP 101430. We place the components on a color-magnitude diagram and discuss each multiple system individually.

“…The large scatter in early micrometer measures, coupled with incomplete phase coverage, has led to a wide variety of solutions for this pair over the past half century; periods have ranged from about 200 years to over 930 years (Scardia 1980(Scardia , 2000b. Interferometric measures are increasingly "running off" the most recently published orbit (Olević & Jovanović 2001).…”
