cds-question@unistra.frmultiple-starssolar-system-planetsradial-velocityWe report three newly discovered exoplanets from the SuperWASP survey. WASP-127b is a heavily inflated super-Neptune of mass 0.18+/-0.02 M_J_ and radius 1.37+/-0.04 R_J_. 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+/-0.08M_J_ and 1.38+/-0.16R_J_, and 1.22+/-0.08M_J_ and 1.09+/-0.05R_J_, respectively. WASP-136b is in a 5.22-day orbit around an F9 subgiant star with a mass of 1.41+/-0.07M_{sun}_ and a radius of 2.21+/-0.22R_{sun}_. 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.2017A&A...599A...3Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/599/A3CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/599/A3https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/599/A3http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/599/A3https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/599/A3https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/599/A3http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/599/A3GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapdefaultJ/A+A/599/A3/table10Photometric time-series obtained by EulerCAM, TRAPPIST, RISE, and ZEISS for WASP-127InstInstrument namemeta.id;instrcharrecnoRecord number assigned by the VizieR team.
