[ ] surveyed 38 nearby M dwarfs from March 2000 to March 2007 with VLT2 and the UVES spectrometer . This data has recently been reanalyzed \citep butler19 , yielding a significant improvement in the Doppler velocity precision . Spurred by this , we have combined the UVES data with velocity sets from HARPS , Magellan/PFS , and Keck/HIRES . Sixteen planet candidates have been uncovered orbiting nine M dwarfs . Five of them are new planets corresponding to radial velocity signals , which are not sensitive to the choice of noise models and are identified in multiple data sets over various timespans . Eight candidate planets require additional observation to be confirmed . We also confirm three previously reported planets . Among the new planets , GJ 180 d and GJ 229A c are super-Earths located in the conservative habitable zones of their host stars . We investigate their dynamical stability using the Monte Carlo approach and find both planetary orbits are robust to the gravitational perturbations of the companion planets . Due to their proximity to the Sun , the angular separation between the host stars and the potentially habitable planets in these two systems is 25 and 59 mas , respectively . They are thus good candidates for future direct imaging by JWST and E-ELT . In addition we find GJ 433 c , a cold super-Neptune belonging to an unexplored population of Neptune-like planets . With a separation of 0.5 as from its host star , GJ 433 c is probably the first realistic candidate for direct imaging of cold Neptunes . A comprehensive survey of these planets is important for the studies of planet formation .
