The extrasolar planet atmosphere and exosphere: Emission and transmission spectroscopy
Giovanna Tinetti, Jean-Philippe Beaulieu
We have entered the phase of extrasolar planets characterization, probing their atmospheres for molecules, constraining their horizontal and vertical temperature profiles and estim…
Diversity among other worlds: characterization of exoplanets by direct detection
J. Schneider, A. Boccaletti, A. Aylward +34
The physical characterization of exoplanets will require to take spectra at several orbital positions. For that purpose, a direct imaging capability is necessary. Direct imaging re…
Super Earth Explorer: A Coronagraphic Off-Axis Space Telescope
J. Schneider, A. Boccaletti, D. Mawet +12
The Super-Earth Explorer is an Off-Axis Space Telescope (SEE-COAST) designed for high contrast imaging. Its scientific objective is to make the physico-chemical characterization of…
Mid-Infrared Properties of Disk Averaged Observations of Earth with AIRS
Thomas Hearty, Inseok Song, Sam Kim +1
We have investigated mid-infrared spectra of Earth obtained by the Atmospheric Infrared Sounder (AIRS) instrument on-board the AQUA spacecraft to explore the characteristics that m…
Using SPICA Space Telescope to characterize Exoplanets
J. R. Goicoechea, B. Swinyard, G. Tinetti +26
We present the 3.5m SPICA space telescope, a proposed Japanese-led JAXA-ESA mission scheduled for launch around 2017. The actively cooled (<5 K), single aperture telescope and mono…
Methane present in an extrasolar planet atmosphere
Mark R. Swain, Gautam Vasisht, Giovanna Tinetti
Molecules present in exoplanetary atmospheres are expected to strongly influence the atmospheric radiation balance, trace dynamical and chemical processes, and indicate the presenc…
Primary transit of the planet HD189733b at 3.6 and 5.8 microns
J. P. Beaulieu, S. Carey, I. Ribas +1
The hot Jupiter HD 189733b was observed during its primary transit using the Infrared Array Camera on the Spitzer Space Telescope. The transit depths were measured simultaneously a…
Water vapour in the atmosphere of a transiting extrasolar planet
Giovanna Tinetti, Alfred Vidal-Madjar, Mao-Chang Liang +10
Water is predicted to be among, if not the most abundant molecular species after hydrogen in the atmospheres of close-in extrasolar giant planets (hot-Jupiters) Several attempts ha…
Spectral signatures of photosynthesis II: coevolution with other stars and the atmosphere on extrasolar worlds
Nancy Y. Kiang, Antigona Segura, Giovanna Tinetti +6
As photosynthesis on Earth produces the primary signatures of life that can be detected astronomically at the global scale, a strong focus of the search for extrasolar life will be…
Infrared Transmission Spectra for Extrasolar Giant Planets
G. Tinetti, M. C. Liang, A. Vidal-Madjar +3
Among the hot Jupiters that transit their parent stars known to date, the two best candidates to be observed with transmission spectroscopy in the mid-infrared (MIR) are HD189733b…
Biosignatures from Earth-Like Planets Around M Dwarfs
Antigona Segura, James F. Kasting, Victoria Meadows +5
Coupled one-dimensional photochemical-climate calculations have been performed for hypothetical Earth-like planets around M dwarfs. Visible, near-infrared and thermal-infrared synt…
The transmission spectrum of Earth-size transiting planets
David Ehrenreich, Giovanna Tinetti, Alain Lecavelier Des Etangs +2
A variety of terrestrial planets with different physical parameters and exotic atmospheres might plausibly exist outside our Solar System, waiting to be detected by the next genera…
Disk-averaged Spectra & light-curves of Earth
G. Tinetti, V. S. Meadows, D. Crisp +6
We are using computer models to explore the observational sensitivity to changes in atmospheric and surface properties, and the detectability of biosignatures, in the globally aver…
Disk-averaged synthetic spectra of Mars
Giovanna Tinetti, Victoria S. Meadows, David Crisp +3
The principal goal of the NASA Terrestrial Planet Finder (TPF) and ESA Darwin mission concepts is to directly detect and characterize extrasolar terrestrial (Earth-sized) planets.…
Constraints in the coupling Star-Life
L. Sertorio, G. Tinetti
If life is sustained by a process of photosynthesis, not necessarily the same existing on Earth, the surface temperature of the star and the orbit of the host planet cannot be what…
