WASP-127b is a heavily inflated super-Neptune of mass 0.18±0.02 MJ and radius 1.37±0.04 RJ. This is one of the least massive planets discovered by the WASP project. It orbits a bright host star (Vmag=10.16) of spectral type G5 with a period of 4.17 days. WASP-127b is a low-density planet that has an extended atmosphere with a scale height of 2500±400km, making it an ideal candidate for transmission spectroscopy. WASP-136b and WASP-138b are both hot Jupiters with mass and radii of 1.51±0.08MJ and 1.38±0.16RJ, and 1.22±0.08MJ and 1.09±0.05RJ, respectively. WASP-136b is in a 5.22-day orbit around an F9 subgiant star with a mass of 1.41±0.07M and a radius of 2.21±0.22R. The discovery of WASP-136b could help constrain the characteristics of the giant planet population around evolved stars. WASP-138b orbits an F7 star with a period of 3.63 days. Its radius agrees with theoretical values from standard models, suggesting the presence of a heavy element core with a mass of ∼10M{earth}. The discovery of these new planets helps in exploring the diverse compositional range of short-period planets, and will aid our understanding of the physical characteristics of both gas giants and low-density planets. Description: Photometric time-series obtained for the WASP-127, WASP-136, and WASP-138, and RV time-series obtained for the three systems. The photometric time-series were obtained using the TRAPPIST and Euler-Swiss telescopes. The RVs were obtained using the Euler/CORALIE spectrograph.
