Spectral Evolution of an Earth-like Planet

  title={Spectral Evolution of an Earth-like Planet},
  author={Lisa Kaltenegger and Wesley A. Traub and Kenneth W. Jucks},
We have developed a characterization of the geological evolution of the Earth’s atmosphere and surface in order to model the observable spectra of an Earth-like planet through its geological history. These calculations are designed to guide the interpretation of an observed spectrum of such a planet by future instruments that will characterize exoplanets. Our models focus on planetary environmental characteristics whose resultant spectral features can be used to imply habitability or the… CONTINUE READING
