Located only 10 pc from the Sun, AU Mic is one of the brightest M-dwarfs in the sky (M1V, V=8.6). Its membership of the beta Pictoris moving group gives it an age of 12 +/- 2 Myr, and it has long been known to host an edge-on debris disk. There has been tentative detection of 2 orbiting planets, that if confirmed around such a young star could change planet formation and migration theories. For this, we analyse HARPS data in order to try and confirm the presence of these planets and/or put constraints on the detection limits. In order to make our results more robust, we perform injection tests, where we artificially introduce a signal into the data and try to recover it, in order to try to asses our sensitivity to the presence of such planets.
