AU Mic debris disk revisited
Linking features in debris disks with planets is the new challenge direct imaging invites us to overcome. Indeed holes, spirals, warps and clumps are many features already found in debris disks and they are most likely created by disk planet interactions. I will present new NICI images in H band of the AU Mic debris disk, a near edge-on debris disk which exhibits several significant dust clumps. These images reveal two clumps located at less than 1'' from the star. I will also introduce a new algorithm MLOCI which has been shown to improve signal-to-noise ratio by a factor of 30 to 400% in the detection of point and extended sources.
