Abstract Wide binary stars are weakly bound systems easily disrupted by encounters with the constituents of the Galaxy. Thus, they provide a unique way to probe the dynamics and mass distribution of the Galactic disk. Here, five samples of stars complete to visual magnitude 14.0 and covering a total of 110 deg2 near the Galactic poles are used to search for wide binary stars. The estimated number of binaries in the total sample is 3 times smaller than that expected from the previous study by Bahcall and Soneira. The pair separation distribution is compared to a model of wide binary properties using a technique developed by Wasserman and Weinberg. The model predicts that wide binaries should be found in the faint half of the sample (mV >12.0), but none are detected.
