NGTS, a new transit search facility in operation in the Southern sky

NGTS is an automated wide field transit survey designed and built to detect transiting Neptune size planet on bright K dwarfs stars. NGTS first light was obtained in summer 2015. First preliminary results as well as details simulations of the survey expectation will be presented during this talk.Bright K dwarfs stars are targets of special interest to look for transiting planets and gather information about planetary structure and the nature of atmospheric composition of exoplanets. Planetary transit to be detected by NGTS will provide us with a unique target sample for further characterization by HARPS, VLT, and later JWST. Interesting synergies with TESS may be found as well on the coolest stars of the sample (M stars).
