ESA White paper: Atmospheric modeling: Setting Biomarkers in context
L. Kaltenegger, F. Selsis
Motivation: ESAs goal to detect biomarkers in Earth-like exoplanets in the Habitable Zone requires theoretical groundwork that needs to be done to model the influence of different…
Cryptic photosynthesis, Extrasolar planetary oxygen without a surface biological signature
C. S. Cockell, L. Kaltenegger, J. A. Raven
On the Earth, photosynthetic organisms are responsible for the production of virtually all of the oxygen in the atmosphere. On the land, vegetation reflects in the visible, leading…
DARWIN - A Mission to Detect, and Search for Life on, Extrasolar Planets
C. S. Cockell, A. Leger, M. Fridlund +47
The discovery of extra-solar planets is one of the greatest achievements of modern astronomy. The detection of planets with a wide range of masses demonstrates that extra-solar pla…
Biomarkers set in context
L. Kaltenegger, F. Selsis
In a famous paper, Sagan et al.(1993) analyzed a spectrum of the Earth taken by the Galileo probe, searching for signatures of life. They concluded that the large amount of O2 and…
Spectral Evolution of an Earth-Like Planet
L. Kaltenegger, W. A. Traub, K. W. Jucks
We have developed a characterization of the geological evolution of the Earths atmosphere and surface in order to model the observable spectra of an Earth-like planet through its g…
Interferometric Space Missions for the Search for Terrestrial Exoplanets: Requirements on the Rejection Ratio
L Kaltenegger, M. Fridlund, A. Karlsson
The requirements on space missions designed to study Terrestrial exoplanets are discussed. We then investigate whether the design of such a mission, specifically the Darwin nulling…
