  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.
