The far future of exoplanet direct characterization (2009)
Schneider, Jean, Leger, Alain, Fridlund, Malcolm, White, Glenn, Eiroa, Carlos, Henning, Thomas, ...
In this outlook we describe what could be the next steps of the direct characterization of habitable exoplanets after first the medium and large mission projects and investigate the benefits of the...
Elemental abundances and minimum mass of heavy elements in the envelope of HD 189733b (2009)
Mousis, Olivier, Lunine, Jonathan I., Tinetti, Giovanna, Griffith, Caitlin A., Showman, Adam P., Alibert, Yann, ...
Oxygen (O) and carbon (C) have been inferred recently to be subsolar in abundance from spectra of the atmosphere of the transiting hot Jupiter HD 189733b. Yet, the mass and radius of the planet...
The extrasolar planet atmosphere and exosphere: Emission and transmission spectroscopy (2008)
Tinetti, Giovanna, Beaulieu, Jean-Philippe
We have entered the phase of extrasolar planets characterization, probing their atmospheres for molecules, constraining their horizontal and vertical temperature profiles and estimating the...
Mid-Infrared Properties of Disk Averaged Observations of Earth with AIRS (2008)
Hearty, Thomas, Song, Inseok, Kim, Sam, Tinetti, Giovanna
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 may someday be...
The presence of methane in the atmosphere of an extrasolar planet (2008)
Swain, Mark R., Vasisht, Gautam, Tinetti, Giovanna
Molecules present in the atmospheres of extrasolar planets are expected to influence strongly the balance of atmospheric radiation, to trace dynamical and chemical processes, and to indicate the...
Methane present in an extrasolar planet atmosphere (2008)
Swain, Mark R., Vasisht, Gautam, Tinetti, Giovanna
Molecules present in exoplanetary atmospheres are expected to strongly influence the atmospheric radiation balance, trace dynamical and chemical processes, and indicate the presence of disequilibrium...
Water vapour in the atmosphere of a transiting extrasolar planet (2007)
Tinetti, Giovanna, Vidal-Madjar, Alfred, Liang, Mao-Chang, Beaulieu, Jean-Philippe, Yung, Yuk, Carey, Sean, ...
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 have been made to...
Kiang, Nancy Y., Segura, Antigona, Tinetti, Giovanna, Blankenship, Robert E., Cohen, Martin, ...
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 photosynthesis,...
The transmission spectrum of Earth-size transiting planets (2005)
Ehrenreich, David, Tinetti, Giovanna, Etangs, Alain Lecavelier Des, Vidal-Madjar, Alfred, Selsis, Franck
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 generation of...

Disk-averaged synthetic spectra of Mars (2004)
Tinetti, Giovanna, Meadows, Victoria S., Crisp, David, Fong, William, Velusamy, Thangasamy, Snively, Heather
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. This first...
