  This paper reports on the detection of two new multiple planet systems around
solar-like stars HD47186 and HD181433. The first system includes a hot Neptune
of 22.78 M_Earth at 4.08-days period and a Saturn of 0.35 M_Jup at 3.7-years
period. The second system includes a Super-Earth of 7.5 M_Earth at 9.4-days
period, a 0.64 M$_Jup at 2.6-years period as well as a third companion of 0.54
M_Jup with a period of about 6 years. These detections increase to 20 the
number of close-in low-mass exoplanets (below 0.1 M_Jup) and strengthen the
fact that 80% of these planets are in a multiple planetary systems.
