Extrasolar Carbon Planets
Marc J. Kuchner, S. Seager
We suggest that some extrasolar planets <~ 60 Earth masses will form substantially from silicon carbide and other carbon compounds. Pulsar planets and low-mass white dwarf planets…
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…
EXPLORE/OC: A Search for Planetary Transits in the Field of NGC 2660
Kaspar von Braun, Brian Lee, Gabriela Mallen-Ornelas +3
We present preliminary photometric results of a monitoring study of the open cluster NGC 2660 as part of the EXPLORE/OC project to find planetary transits in Galactic open clusters…
Uses of Linear Polarization as a Probe of Extrasolar Planet Atmospheres
S. Saar, S. Seager
We point out some advantages of making observations of extrasolar planets in linearly polarized (LP) light. Older cool stars have quite low levels (~ 10^-4 to 10^-5) of fractional…
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…
A Model of the Temporal Variability of Optical Light from Extrasolar Terrestrial Planets
Eric B. Ford, Sara Seager, Edwin L. Turner
The light scattered by an extrasolar Earth-like planet's surface and atmosphere will vary in intensity and color as the planet rotates; the resulting light curve will contain infor…
