Abstract (EN): 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 6.6 M(Earth) and a "Neptune" planet with minimum mass of 18 M(Earth), both orbiting their parent stars within a distance of 0.05 AU and a period of approximately four days. These detections strengthen the argument that low-mass planets are primarily found in multiple-planetary systems.
