OIR Research: Exoplanets
 

Extrasolar planet Search (Direct imaging) & Atmosphere modelling:

Using a radiative transfer and climate models developed at the CfA and elsewhere, we model Earth and extrasolar planet atmospheres and their spectra to identify spectral fingerprints which may characterize these worlds. This work is fundamental to upcoming projects that will observe photons from extrasolar planets directly from space or from the ground, (e.g. JWST, Terrestrial Planet Finder and Darwin)

Extrasolar planet Transit Search & The Kepler Science Team
CfA is playing a major role in NASA's Kepler mission to search for habitable earth-like planets by looking for transiting systems. CfA scientists are responsible for preparing the Kepler Input Catalog for the selection of targets, and for follow-up observations to confirm and characterize planetary systems.

OIR scientists are actively involved in follow-up observations of transiting-planet candidates identified by ground-based photometric surveys such as OGLE, Vulcan, TrES, HAT, and KELT, Spectroscopy is used to sort out stellar systems masquerading as transiting planets and to derive spectroscopic orbits for mass determinations. Photometry with KeplerCam is used to derive high-quality light curves for accurate determinations of planet size.

We can distinguish 6 different evolution stages by just looking at the spectral fingerprints of Earth (here shown when it was very young).
