    NASA Astrobiology Institute, Pasadena, California, USA
    Astrobiology 6:34-47. 2006
    ..CH4, N2O, CO2, O3, and H2O are visible in the near-infrared (1-5 microm). A comprehensive three-dimensional model of the Earth is needed to produce a good fit with the observations...

    European Space Agency, Institut d Astrophysique de Paris, IAP Section Plan├Ętes extra solaires, 98 bis boulevard Arago, 75014 Paris, France
    Orig Life Evol Biosph 36:541-7. 2006
    ..Marine vegetation is far more difficult to detect. We explored also the detectability of an exo-vegetation responsible for producing a signature that is red-shifted with respect to the Earth vegetation's one...

    Giovanna Tinetti
    NASA Astrobiology Institute, California Institute of Technology, Pasadena, USA
    Astrobiology 6:881-900. 2006
    ..The detectability of phytoplankton was also explored, but was found to be more difficult to detect in the disk-average than land vegetation...
  4. ncbi request reprint Disk-averaged synthetic spectra of Mars
    Giovanna Tinetti
    NASA Astrobiology Institute, National Research Council, California Institute of Technology, Pasadena, California 91125, USA
    Astrobiology 5:461-82. 2005
    ..We also considered the differences in the spectral appearance of an increasingly ice-covered Mars, as a function of spectral resolution, signal-to-noise and integration time for both TPF-C and TPFI/ Darwin...
  5. ncbi request reprint Biosignatures from Earth-like planets around M dwarfs
    Antigona Segura
    Infrared Processing and Analysis Center, California Institute of Technology, Pasadena, CA 91125, USA
    Astrobiology 5:706-25. 2005
    ..The simultaneous detection of O2 (or O3) and a reduced gas in a planet's atmosphere has been suggested as strong evidence for life. Planets circling M stars may be good locations to search for such evidence...
  6. ncbi request reprint Spectral signatures of photosynthesis. II. Coevolution with other stars and the atmosphere on extrasolar worlds

    NASA Goddard Institute for Space Studies, New York, New York 10025, USA
    Astrobiology 7:252-74. 2007
    ..1 microm for anoxygenic photosynthesis. Under water, organisms would still be able to survive ultraviolet flares from young M stars and acquire adequate light for growth...

    Giovanna Tinetti
    European Space Agency, Frascati 00044, Italy
    Nature 448:169-71. 2007
    ..We explain the report of a non-detection of water on HD 189733b (ref. 4) as being a consequence of the nearly isothermal vertical profile of the planet's atmosphere...
