Science goals and new mission concepts for future exploration of Titan's atmosphere geology and habitability: Titan POlar Scout/orbitEr and In situ lake lander and DrONe explorer (POSEIDON)
Sébastien Rodriguez, Sandrine Vinatier, Daniel Cordier +61
In response to ESA Voyage 2050 announcement of opportunity, we propose an ambitious L-class mission to explore one of the most exciting bodies in the Solar System, Saturn largest m…
Combining angular differential imaging and accurate polarimetry with SPHERE/IRDIS to characterize young giant exoplanets
Rob G. van Holstein, Frans Snik, Julien H. Girard +11
Young giant exoplanets emit infrared radiation that can be linearly polarized up to several percent. This linear polarization can trace: 1) the presence of atmospheric cloud and ha…
Search for water in a super-Earth atmosphere: High-resolution optical spectroscopy of 55 Cancri e
Lisa J. Esteves, Ernst J. W. De Mooij, Ray Jayawardhana +2
We present the analysis of high-resolution optical spectra of four transits of 55Cnc e, a low-density, super-Earth that orbits a nearby Sun-like star in under 18 hours. The inferre…
The slow spin of the young sub-stellar companion GQ Lupi b and its orbital configuration
Henriette Schwarz, Christian Ginski, Remco J. de Kok +3
The spin of a planet or brown dwarf is related to the accretion process, and therefore studying spin can help promote our understanding of the formation of such objects. We present…
The EChO science case
Giovanna Tinetti, Pierre Drossart, Paul Eccleston +347
The discovery of almost 2000 exoplanets has revealed an unexpectedly diverse planet population. Observations to date have shown that our Solar System is certainly not representativ…
HCN ice in Titan's high-altitude southern polar cloud
Remco J. de Kok, Nicholas A. Teanby, Luca Maltagliati +2
Titan's middle atmosphere is currently experiencing a rapid change of season after northern spring arrived in 2009. A large cloud was observed for the first time above Titan's sout…
Titan's atmosphere as observed by Cassini/VIMS solar occultations: CH, CO and evidence for CH absorption
L. Maltagliati, B. Bézard, S. Vinatier +6
We present an analysis of the VIMS solar occultations dataset, which allows us to extract vertically resolved information on the characteristics of Titan's atmosphere between 100-7…
The fast spin-rotation of a young extrasolar planet
Ignas Snellen, Bernhard Brandl, Remco de Kok +3
The spin-rotation of a planet arises from the accretion of angular momentum during its formation, but the details of this process are still unclear. In the solar system, the equato…
Exploring the Diversity of Jupiter-Class Planets (Discussion Meeting Contribution)
Leigh N. Fletcher, Patrick G. J. Irwin, Joanna K. Barstow +3
Royal Society Discussion Meeting (2013) `Characterizing exoplanets'. Of the 900+ confirmed exoplanets discovered since 1995 for which we have constraints on their mass (i.e., not i…
Identifying new opportunities for exoplanet characterisation at high spectral resolution
Remco J. de Kok, Jayne Birkby, Matteo Brogi +4
[Abridged] Recently, there have been a series of detections of molecules in the atmospheres of extrasolar planets using high spectral resolution (R~100,000) observations, mostly us…
Search for Rayleigh scattering in the atmosphere of GJ1214b
Ernst J. W. de Mooij, Matteo Brogi, Remco J. de Kok +8
We investigate the atmosphere of GJ1214b, a transiting super-Earth planet with a low mean density, by measuring its transit depth as a function of wavelength in the blue optical po…
Detection of carbon monoxide in the high-resolution day-side spectrum of the exoplanet HD 189733b
Remco J. de Kok, Matteo Brogi, Ignas A. G. Snellen +3
[Abridged] After many attempts over more than a decade, high-resolution spectroscopy has recently delivered its first detections of molecular absorption in exoplanet atmospheres, b…
Finding extraterrestrial life using ground-based high-resolution spectroscopy
Ignas Snellen, Remco de Kok, Rudolf Le Poole +2
Exoplanet observations promise one day to unveil the presence of extraterrestrial life. Atmospheric compounds in strong chemical disequilibrium would point to large-scale biologica…
The signature of orbital motion from the dayside of the planet tau Bootis b
M. Brogi, I. A. G. Snellen, R. J. de Kok +3
The giant planet orbiting tau Bootis was among the first extrasolar planets to be discovered through the reflex motion of its host star. It is one of the brightest known and most n…
Exoplanet-atmospheres at high spectral resolution: A CRIRES survey of hot-Jupiters
Ignas Snellen, Remco de Kok, Ernst de Mooij +3
Recently, we presented the detection of carbon monoxide in the transmission spectrum of extrasolar planet HD209458b, using CRIRES, the Cryogenic high-resolution Infrared Echelle Sp…
The orbital motion, absolute mass, and high-altitude winds of exoplanet HD209458b
Ignas A. G. Snellen, Remco J. de Kok, Ernst J. W. de Mooij +1
For extrasolar planets discovered using the radial velocity method, the spectral characterization of the host star leads to a mass-estimate of the star and subsequently of the orbi…
