    • A new Neptune-mass planet orbiting HD219828 
      Melo, C.; Santos, N. C.; Gieren, W.; Pietrzynski, Grzegorz; Ruiz González, María Teresa; Sousa, S. G.; Bouchy, F.; Lovis, C.; Mayor, M.; Pepe, F.; Queloz, D.; Da Silva, R.; Udry, S. (2007)
      Two years ago a new benchmark for the planetary survey was set with the discoveries of three extrasolar planets with masses below 20 M-circle plus. In particular, the serendipitous discovery of the 14 M-circle plus planet ...
    • Millimagnitude optical photometry for the transiting planetary candidate OGLE-TR-109 
      Fernández, José Miguel; Minniti, Dante; Pietrzynski, Grzegorz; Gieren, Wolfgang; Ruiz González, María Teresa; Zoccali, Manuela; Udalski, Andrzej; Szeifert, Thomas (UNIV CHICAGO PRESS, 2006-08-10)
      We present precise V-band photometry for the low-amplitude transit candidate star OGLE-TR-109. This is an extreme case among the transiting candidates found by the OGLE group because of the early spectral type of the star ...
    • The "666" collaboration on OGLE transits I. Accurate radius of the planets OGLE-TR-10b and OGLE-TR-56b with ... 
      Pont, F.; Moutou, C.; Gillón, M.; Udalski, A.; Bouchy, F.; Fernandes, J. M.; Gieren, W.; Mayor, M.; Mazeh, T.; Minniti, D.; Melo, C.; Naef, D.; Pietrzynski, Grzegorz; Queloz, D.; Ruiz González, María Teresa; Santos, N. C.; Udry, S. (2007)
      Transiting planets are essential to study the structure and evolution of extra-solar planets. For that purpose, it is important to measure precisely the radius of these planets. Here we report new high-accuracy photometry ...
