A near-infrared interferometric survey for bright exozodiacal disks

Since 2006, we have been conducting a near-infrared survey for bright exozodiacal disks using the FLUOR interferometer at the CHARA array. The first results of this survey, encompassing 42 nearby main sequence stars, will be presented and discussed. The unexpectedly high occurence rate and its apparent correlation with spectral type question the nature of the circumstellar excess emission detected at K band. I will also describe the current efforts to extend our stellar sample, including in the Southern hemisphere thanks to the PIONIER instrument at VLTI. First results obtained with VLTI/PIONIER will be discussed.
