Vegetation's Red Edge: A Possible Spectroscopic Biosignature of Extraterrestrial Plants
Sara Seager, Edwin L. Turner, Justin Schafer +1
Earth's deciduous plants have a sharp order-of-magnitude increase in leaf reflectance between approximately 700 and 750 nm wavelength. This strong reflectance of Earth's vegetation…
Evidence for Planet-Planet Scattering in Upsilon Andromedae
Eric B. Ford, Verene Lystad, Frederic A. Rasio
Doppler spectroscopy has detected 136 planets around nearby stars. A major puzzle is why their orbits are highly eccentric, while all planets in our Solar System are on nearly circ…
Choice of Observing Schedules for Astrometric Planet Searches
Eric B. Ford
The Space Interferometry Mission (SIM) will make precise astrometric measurements that can be used to detect planets around nearby stars. Since observational time will be extremely…
The Vegetation Red Edge Spectroscopic Feature as a Surface Biomarker
S. Seager, E. B. Ford
The search for Earth-like extrasolar planets is in part motivated by the potential detection of spectroscopic biomarkers. Spectroscopic biomarkers are spectral features that are ei…
