  We report on a high angular resolution survey of circumstellar disks around
24 northern sky Be stars. The K-band continuum survey was made using the CHARA
Array long baseline interferometer (baselines of 30 to 331 m). The
interferometric visibilities were corrected for the flux contribution of
stellar companions in those cases where the Be star is a member of a known
binary or multiple system. For those targets with good uv coverage, we used a
four parameter Gaussian elliptical disk model to fit the visibilities and to
determine the axial ratio, position angle, K-band photospheric flux
contribution, and angular diameter of the disk major axis. For the other
targets with relatively limited uv coverage, we constrained the axial ratio,
inclination angle, and or disk position angle where necessary in order to
resolve the degeneracy between possible model solutions. We also made fits of
the ultraviolet and infrared spectral energy distributions to estimate the
stellar angular diameter and infrared flux excess of each target. The mean
ratio of the disk diameter (measured in K-band emission) to stellar diameter
(from SED modeling) is 4.4 among the 14 cases where we reliably resolved the
disk emission, a value which is generally lower than the disk size ratio
measured in the higher opacity Halpha emission line. We estimated the
equatorial rotational velocity from the projected rotational velocity and disk
inclination for 12 stars, and most of these stars rotate close to or at the
critical rotational velocity.
