We conducted several simulations to investigate the feasibility of obtaining spectroscopy of extrasolar planets using the Near-Infrared Spectrograph (NIRSpec) on the James Webb Space Telescope (JWST). NASA's Kepler Mission, which is scheduled for launch in 2008, expects to find a wealth of both Jupiter-mass and Earth-mass planets transiting their host stars which could serve as candidates for NIRSpec observations when JWST launches. Using current published specifications of NIRSpec and models of star and planet spectra, we determined lower magnitude bounds for which spectral features can be resolved for planets around host stars of various spectral classes. We also investigated other parameters, such as transit length and orbital period, and their effects on the signal to noise and quality of the simulated spectra. We acknowledge the Space Telescope Science Institute summer student program for funding this project.
