Variations related to stellar activity and correlated noise can prevent thedetections of low-amplitude signals in radial velocity data if not accountedfor. This can be seen as the greatest obstacle in detecting Earth-like planetsorbiting nearby stars with Doppler spectroscopy regardless of developments ininstrumentation and rapidly accumulating amounts of data. We use a statisticalmodel that is not sensitive to aperiodic and/or quasiperiodic variability ofstellar origin. We demonstrate the performance of our model by re-analysing theradial velocities of the moderately active star CoRoT-7 ($\log R_{\rm HK} =-4.61$) with a transiting planet whose Doppler signal has proven ratherdifficult to detect. We find that the signal of the transiting planet can berobustly detected together with signals of two other planet candidates. Ourresults suggest that rotation periods of moderately active stars can befiltered out of the radial velocity noise, which enables the detections oflow-mass planets orbiting such stars.
