Spectra of Two Extrasolar Planets
Researchers from NAI’s Carnegie Institution of Washington and NASA Goddard Space Flight Center Teams have a new paper in Nature describing the infrared spectrum of exoplanet HD 209458b as obtained by the NASA Spitzer Space Telescope. Scientists from NAI’s University of Arizona and Alumni Virtual Planetary Laboratory Teams are contributing authors on a similar paper in Astrophysical Journal Letters which details the spectrum of exoplanet HD 189733b. Both sets of results show relatively flat spectra, with...
