      We present the discovery of a Neptune-mass planet OGLE-2007-BLG-368Lb with a planet–star mass ratio of q = [9.5 ± 2.1] × 10−5 via gravitational microlensing. The planetary deviation was detected in real-time thanks to ...

      Hoyer, Sergio; Rojo, P.; López Morales, M.; Díaz, R. F.; Chambers, J.; Minniti, D. (IOP PUBLISHING, 2011-05-20)
      We report five new transit epochs of the extrasolar planet OGLE-TR-111b, observed in the v-HIGH and Bessell I bands with the FORS1 and FORS2 at the ESO Very Large Telescope between 2008 April and May. The new transits have ...
    • Ground-based detection of calcium and possibly scandium and hydrogen in the atmosphere of HD209458b 

      Astudillo Defru, N.; Rojo, P. (EDP Sciences, 2013)
      Context. Since the first exoplanetary atmosphere detection using the Hubble Space Telescope, characterization of exoplanet atmospheres from the ground have been playing an increasingly important role in the analysis of ...
    • High-resolution spectroscopic search for the thermal emission of the extrasolar planet HD 217107 b 

      Cubillos, P. E.; Rojo, P.; Fortney, J. J. (EDP SCIENCES, 2011-05)
      We analyzed the combined near-infrared spectrum of a star-planet system with thermal emission atmospheric models, based on the composition and physical parameters of the system. The main objective of this work is to obtain ...
    • MASS AND DENSITY OF THE B-TYPE ASTEROID (702) ALAUDA 

      Rojo, P.; Margot, J. L. (2011-02-01)
      Observations with the adaptive optics system on the Very Large Telescope reveal that the outer main belt asteroid (702) Alauda has a small satellite with primary to secondary diameter ratio of ∼56. The secondary revolves ...
    • A method to remove fringes from images using wavelets 

      Rojo, P.; Harrington, Joseph (UNIV CHICAGO PRESS, 2006-09-20)
      We have developed a new method that uses wavelet analysis to remove interference fringe patterns from images. This method is particularly useful for flat fields in the common case where fringes vary between the calibration ...
    • Near-infrared integral-field spectra of the planet/brown dwarf companion AB Pictoris b 

      Bonnefoy, M.; Chauvin, G.; Rojo, P.; Allard, F.; Lagrange, Anne Marie; Homeier, D.; Dumas, C.; Beuzit, J.-L. (EDP Sciences, 2010)
      Context. We have already imaged a co-moving companion at a projected separation of ∼260 AU from the young star AB Pic A. Evolutionary model predictions based on JHK photometry of AB Pic b suggest a mass of ∼13−14 MJup, ...
