Adaptive optics and speckle imaging of Wolf 327. Left panel: Keck NIR AO imaging and sensitivity curve for Wolf 327 taken with the Kcont filter. The black points represent the 5σ limits and are separated in steps of 1 FWHM; the purple area represents the 1σ azimuthal dispersion of the contrast determinations (see text). The inset image of the primary target shows no additional close-in companions. Right panel: I_c band speckle sensitivity curve of Wolf 327 taken with the SPeckle Polarimeter (SPP) at the Caucasian Observatory. No stellar companions are detected with magnitudes brighter than ΔI_c = 3.9 and 6.2 at ρ = 0.″25 and 1.″0 respectively. The inset shows the speckle autocorrelation function.
