    • Centroid vetting of transiting planet candidates from the next generation transit survey 
      Gunther, Maximilian N.; Queloz, Didier; Gillen, Edward; Jenkins, James Stewart (Oxford university press, 2017)
      The Next Generation Transit Survey (NGTS), operating in Paranal since 2016, is a wide-field survey to detect Neptunes and super-Earths transiting bright stars, which are suitable for precise radial velocity follow-up and ...
    • Refined physical parameters for Chariklo's body and rings from stellar occultations observed between 2013 and 2020

L.; Unda Sanzana, E.; Yamashita, T. A. R.; Winter, O. C.; Zapata, A.; Zuluaga, C. A. (EDP Sciences, 2021)
      Context. The Centaur (10199) Chariklo has the first ring system discovered around a small object. It was first observed using stellar occultation in 2013. Stellar occultations allow sizes and shapes to be determined with ...
    • Size and shape of chariklo from multi epoch stellar occultations 
      Leiva, R.; Sicardy, B.; Camargo, J. I. B.; Kervella, P. (IOP Publishing Ltd, 2017)
      We use data from five stellar occultations observed between 2013 and 2016 to constrain Chariklo's size and shape, and the ring reflectivity. We consider four possible models for Chariklo (sphere, Maclaurin spheroid, triaxial ...
    • The state of Pluto’s atmosphere in 2012–2013 
      Bosh, A. S.; Person, M. J.; Levine, S. E.; Zuluaga, C. A.; Zangari, A. M.; Gulbis, A. A. S.; Schaefer, G. H.; Dunham, E. W.; Babcock, Bryce A.; Davis, A. B.; Pasachoff, J. M.; Rojo Rubke, Patricio; Servajean, E.; Forster, Francisco; Oswalt, T.; Batcheldor, D.; Bell, D.; Bird, P.; Fey, D.; Fulwider, T.; Geisert, E.; Hastings, D.; Keuhler, C.; Mizusawa, T.; Solenski, P.; Watson, B. (Elsevier, 2015)
      We observed two stellar occultations on UT 4 May 2013 and UT 9 September 2012, with the aim of measuring Pluto’s atmospheric parameters. Both of these events were observed by world-wide collaborations of many observers, ...
    • The structure of Chariklo's rings from stellar occultations 
      Berard, D.; Sicardy, B.; Camargo, J. I. B.; Kervella, P. (IOP Publishing Ltd, 2017)
      Two narrow and dense rings (called C1R and C2R) were discovered around the Centaur object (10199) Chariklo during a stellar occultation observed on 2013 June 3. Following this discovery, we planned observations of several ...
    • Trio of Stellar Occultations by Pluto One Year Prior to Newhorizons' Arrival 
      Pasachoff, Jay M.; Person, Michael J.; Bosh, Amanda S.; Sickafoose, Amanda A.; Zuluaga, Carlos; Levine, Stephen E.; Osip, David J.; Schiff, Avery; Seeger, Christina H.; Babcock, Bryce A.; Rojo Rubke, Patricio; Servajean, Elise (IOP Publishing, 2016)
      We observed occultations by Pluto during a predicted series of events in 2014 July with the 1 m telescope of the Mt. John Observatory in New Zealand. The predictions were based on updated astrometry obtained in the previous ...
    • Unmasking the hidden NGTS-3Ab: A hot Jupiter in an unresolved binary system 
      Günther, Maximilian N.; Queloz, Didier; Gillen, Edward; Delrez, Laetitia; Bouchy, François; McCormac, James; Smalley, Barry; Almleaky, Yaseen; Armstrong, David J.; Bayliss, Daniel; Burdanov, Artem; Burleigh, Matthew; Cabrera, Juan; Casewell, Sarah L.; Cooke, Benjamin F; Csizmadia, Szilárd; Ducrot, Elsa; Eigmuller, Philipp; Erikson, Anders; Gänsicke, Boris; Gibsonq, Neale; Gillon, Michaël; Goad, Michael; Jehin, Emmanuël; Jenkins, James Stewart; Louden, Tom; Moyano, Maximiliano; Murray, Catriona; Pollacco, Don; Poppenhaeger, Katja; Rauer, Heike; Raynard, Liam; Smith, Alexis; Sohy, Sandrine; Thompson, Samantha; Udry, Stéphane; Watson, Christopher; West, Richard; Wheatley, Peter (Oxford University Press, 2018)
      We present the discovery of NGTS-3Ab, a hot Jupiter found transiting the primary star of an unresolved binary system. We develop a joint analysis of multi-colour photometry, centroids, radial velocity (RV) cross-correlation ...
