Detection limits of giant planets with Jupiter mass vs. the projected distance from the central star for stars with known debris disks. The detections are expressed at the 5σ level, using VLT/NaCo in ADI mode, after LOCI (close-in region) and nADI (background-limited region) processing. The COND03 (Baraffe et al. 2003) mass–luminosity relationship is used to convert from L′ contrast to Jupiter mass. For AU Mic, the model does not reach below 0.5 M_J, therefore we cut the curve when it reached this limit.
