  • The EBLM project : III. A Saturn-size low-mass star at the hydrogen-burning limit 

    Von Boetticher, Alexander; Triaud, Amaury H.M.J.; Queloz, DIdier; Gill, Sam; Lendl, Monika; Delrez, Laetitia; Anderson, David R.; Cameron, Andrew Collier; Faedi, Francesca; Gillon, Michaël; Chew, Yilen Gómez Maqueo; Hebb, Leslie; Hellier, Coel; Jehin, Emmanuël; Maxted, Pierre F.L.; Martin, David V.; Pepe, Francesco; Pollacco, Don; Ségransan, Damien; Smalley, Barry; Udry, Stéphane; West, Richard (2017-08-01) - Journal article
    We report the discovery of an eclipsing binary system with mass-ratio q ∼ 0.07. After identifying a periodic photometric signal received by WASP, we obtained CORALIE spectroscopic radial velocities and follow-up light ...
  • The EBLM Project : IV. Spectroscopic orbits of over 100 eclipsing M dwarfs masquerading as transiting hot-Jupiters 

    Triaud, Amaury H. M. J.; Martin, David V.; Ségransan, Damien; Smalley, Barry; Maxted, Pierre F. L.; Anderson, David R.; Bouchy, François; Collier Cameron, Andrew; Faedi, Francesca; Gómez Maqueo Chew, Yilen; Hebb, Leslie; Hellier, Coel; Marmier, Maxime; Pepe, Francesco; Pollacco, Don; Queloz, Didier; Udry, Stéphane; West, Richard (2017-12) - Journal article
    We present 2271 radial velocity measurements taken on 118 single-line binary stars, taken over eight years with the CORALIE spectrograph. The binaries consist of F/G/K primaries and M dwarf secondaries. They were initially ...
  • Peculiar architectures for the WASP-53 and WASP-81 planet-hosting systems 

    Triaud, Amaury H. M. J.; Neveu-VanMalle, Marion; Lendl, Monika; Anderson, David R.; Collier Cameron, Andrew; Delrez, Laetitia; Doyle, Amanda; Gillon, Michaël; Hellier, Coel; Jehin, Emmanuël; Maxted, Pierre F. L.; Ségransan, Damien; Smalley, Barry; Queloz, Didier; Pollacco, Don; Southworth, John; Tregloan-Reed, Jeremy; Udry, Stéphane; West, Richard (2017-05) - Journal article
    We report the detection of two new systems containing transiting planets. Both were identified by WASP as worthy transiting planet candidates. Radial velocity observations quickly verified that the photometric signals were ...
  • Spitzer observations of the thermal emission from WASP-43b 

    Blecic, Jasmina; Harrington, Joseph; Madhusudhan, Nikku; Stevenson, Kevin B.; Hardy, Ryan A.; Cubillos, Patricio E.; Hardin, Matthew; Bowman, Oliver; Nymeyer, Sarah; Anderson, David R.; Hellier, Coel; Smith, Alexis M. S.; Collier Cameron, Andrew (2014-02-01) - Journal article
    WASP-43b is one of the closest-orbiting hot Jupiters, with a semimajor axis of a = 0.01526 ± 0.00018 AU and a period of only 0.81 days.However, it orbits one of the coolest stars with a hot Jupiter (T* = 4520 ± 120 K), ...
  • A transient transit signature associated with the young star RIK-210 

    David, Trevor J.; Petigura, Erik A.; Hillenbrand, Lynne A.; Cody, Ann Marie; Cameron, Andrew Collier; Stauffer, John R.; Fulton, B. J.; Isaacson, Howard T.; Howard, Andrew W.; Howell, Steve B.; Everett, Mark E.; Wang, Ji; Benneke, Björn; Hellier, Coel; West, Richard G.; Pollacco, Don; Anderson, David R. (2017-01-27) - Journal article
    We find transient transit-like dimming events within the K2 time series photometry of the young star RIK-210 in the Upper Scorpius OB association. These dimming events are variable in depth, duration, and morphology. High ...
  • WASP-135b : a highly irradiated, inflated hot Jupiter orbiting a G5V star 

    Spake, Jessica J.; Brown, David John Alexander; Doyle, Amanda P.; Hébrard, Guillaume; McCormac, James; Armstrong, David J.; Pollacco, Don; Chew, Yilen Gómez Maqueo; Anderson, David R.; Barros, Susana C. C.; Bouchy, François; Boumis, Panayotis; Bruno, Giovanni; Cameron, Andrew Collier; Courcol, Bastien; Davies, Guy R.; Faedi, Francesca; Hellier, Coel; Kirk, James; Lam, Kristine W. F.; Liakos, Alexios; Louden, Tom; Maxted, Pierre F. L.; Osborn, Hugh P.; Palle, Enric; Arranz, Jorge Prieto; Udry, Stéphane; Walker, Simon R.; West, Richard G.; Wheatley, Peter J. (2016-01-14) - Journal article
    We report the discovery of a new transiting planet from the WASP survey. WASP-135b is a hot Jupiter with a radius of 1.30 pm 0.09 Rjup, a mass of 1.90 pm 0.08 Mjup and an orbital period of 1.401 days. Its host is a Sun-like ...
  • WASP-80b has a dayside within the T-dwarf range 

    Triaud, Amaury H. M. J.; Gillon, Michael; Ehrenreich, David; Herrero, Enrique; Lendl, Monika; Anderson, David R.; Cameron, Andrew Collier; Delrez, Laetitia; Demory, Brice-Olivier; Hellier, Coel; Heng, Keving; Jehin, Emmanuel; Maxted, Pierre F. L.; Pollacco, Don; Queloz, Didier; Ribas, Ignasi; Smalley, Barry; Smith, Alexis Michael Sheridan; Udry, Stephane (2015-07-01) - Journal article
    WASP-80b is a missing link in the study of exo-atmospheres. It falls between the warm Neptunes and the hot Jupiters and is amenable for characterisation, thanks to its host star's properties. We observed the planet through ...
