cds-question@unistra.frmultiple-starsexoplanetsstellar-spectral-typesproper-motionsstellar-distancestellar-massesstellar-agesstellar-radiichemical-abundancesapparent-magnitudeGiven the frequency of stellar multiplicity in the solar neighborhood, it is important to study the impacts this can have on exoplanet properties and orbital dynamics. There have been numerous imaging survey projects established to detect possible low-mass stellar companions to exoplanet host stars. Here, we provide the results from a systematic speckle imaging survey of known exoplanet host stars. In total, 71 stars were observed at 692 and 880 nm bands using the Differential Speckle Survey Instrument at the Gemini-north Observatory. Our results show that all but two of the stars included in this sample have no evidence of stellar companions with luminosities down to the detection and projected separation limits of our instrumentation. The mass-luminosity relationship is used to estimate the maximum mass a stellar companion can have without being detected. These results are used to discuss the potential for further radial velocity follow-up and interpretation of companion signals.2017AJ....154..184Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/154/184CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/239 : The Hipparcos and Tycho Catalogues (ESA 1997)I/311 : Hipparcos, the New Reduction (van Leeuwen, 2007)J/A+AS/137/451 : Radial velocities.
