  1. SPEEDY POSTERS Molecules in the tmospheres of extrasolar planets Observatoire de Paris, Salle Cassini, November 19-21, 2008

  2. SPEEDY POSTERS GONE IN 60 SECONDS !

  3. Ground-based detection of the secondary eclipse of TrES-3bErnst de Mooij & Ignas Snellen, Leiden Observatory Observations with the William Herschel Telescope ΔF = -0.234± 0.028% Δφ = -0.0041 ± 0.0018

  4. Exoplanet spectroscopy: the Hubble case Pieter Deroo M. Swain, G. Vasisht, A. Tanner, P. Chin, G. Tinetti, J. Bouwman, D. Deming, Y. Yung

  5. FIRST project: Planet detection from the ground at visible to near-infrared wavelengths without using Adaptive Optics T. Kotani A new idea for aperture masking: FIRST (Fibered Imager foR Single Telescope)‏ Very high dynamic range imaging up to 106 at visible wavelengths Lenslet array Single-mode fibers Redundant Array + Corrugated Wavefront Non-Redundant Array + Spatially Filtered Wavefront Lab Demonstration Pupil remapping + single-mode fiber CCD Imaging Reconstructed Image

  6. Exoplanet research with SAFARI: A far-IR imaging spectrometer for SPICA Javier R. Goicoechea(UCM/CSIC, Madrid, Spain) Kate Isaak(Cardiff University, U.K.) Bruce Swinyard(Rutherford Appleton Laboratory, U.K.) On behalf of the SAFARI consortium • Science questions in the field of exoplanets and planet formation with SAFARI: • Stellar far-IRphotometric excesses(disks!). • Protoplanetary disks: from gas to“snow lines”. • Primary and secondary transits in the far-IR. • Searching forspectral signaturesof transiting exoplanets (water vapor, HD, biomarkers…). • JAXA-led SPICA Mission:mid- and far-IR • cooled (<5 K) space telescope (D~3.5m) • SAFARI instrument:far-IRimaging-FTS • Wavelength coverage of ~33-210mm • Field of view of ~2’ x 2’ • Spectroscopy (R~2,000) & photometry (R~3)

  7. What could be observed in the case of Super-Ios and Hyper-Ios?Danielle Briot & Jean Schneider We study the case of a Earth, or a Super-Earth with a volcanic activity as strong as Io’s. We call such an object a Super-Io and a Hyper-Io in the case of a Super-Earth. • In case of a transit, sulphur dioxid could be observed in the atmosphere • These objects are very good candidates for secondary transits observations, specially at 3.5 m, and the hot spots corresponding to volcanoes could be detected in the first part and the last part of the secondary transit. - These objects could be easily observed by imaging in the infrared, specially in a case of a cool star.

  9. The young, tight and low mass binary TWA22AB: a new calibrator for evolutionary models ? M. Bonnefoy1, G. Chauvin1, C. Dumas2, A-M. Lagrange1, H. Beust1, M. Desort1, J-L. Beuzit1 and I. Song3 1 Laboratoire d’Astrophysique - Observatoire de Grenoble (LAOG), FRANCE 2 European Southern Observatory (ESO), Chile 3 Department of Physics and Astronomy, University of Georgia, USA E-mail :mickael.bonnefoy@obs.ujf-grenoble.fr Aim: calibrating evolutionary models at young ages and at the substellar boundary. Observations of the young low mass binary TWA22 AB with SINFONI and NACO Physical parameters (Dynamical mass, effective temperatures, gravities, luminosity, distance, age) Comparison to evolutionary models predictions Images NIR Spectra Come to see me !
