Abstract (from CDS):

We present the detections of three multiple systems within the HARPS volume-limited sample. Among the six planets discussed in this paper, we have identified a ``super-Earth'' planet with a minimum mass of 6.6MEarth and a ``Neptune'' planet with minimum mass of 18MEarth, both orbiting their parent stars within a distance of 0.05AU and a period of approximately four days. These detections strengthen the argument that low-mass planets are primarily found in multiple-planetary systems.
