cds-question@unistra.frinterferometrymultiple-starssolar-system-planetsA study of the host stars to exoplanets is important for understanding their environment. To that end, we report new speckle observations of a sample of exoplanet host primaries. The bright exoplanet host HD 8673 (= HIP 6702) is revealed to have a companion, although at this time we cannot definitively establish the companion as physical or optical. The observing lists for planet searches and for these observations have for the most part been pre-screened for known duplicity, so the detected binary fraction is lower than what would otherwise be expected. Therefore, a large number of double stars were observed contemporaneously for verification and quality control purposes, to ensure that the lack of detection of companions for exoplanet hosts was valid. In these additional observations, 10 pairs are resolved for the first time and 60 pairs are confirmed.2011AJ....142..176Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/142/176CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/wds : The Washington Visual Double Star Catalog (Mason+ 2001-2013)J/A+AS/105/503 : Binary star speckle measurements (Balega+ 1994)J/AJ/119/3084 : ICCD speckle obs. of binary stars.
