  We present results of a coronographic imaging search for circumstellar dust
disks with the Adaptive Optics Near Infrared System (ADONIS) at the ESO 3.6m
telescope in La Silla (Chile). 22 candidate stars, known to be orbited by a
planet or to show infrared excess radiation, were examined for circumstellar
material. In the PSF-subtracted images no clear disk was found. We further
determine the detection sensitivities and outline how remaining atmospheric
fluctuations still can hamper adaptive optics observations.
