Towards a Small Prototype Planet Finding Interferometer: The next step in planet finding and characterization in the infrared
W. C. Danchi, D. Deming, K. G. Carpenter +9
During the last few years, considerable effort has been directed towards large-scale (>> $1 Billion US) missions to detect and characterize earth-like planets around nearby stars,…
A Ground-Based Search for Thermal Emission from the Exoplanet TrES-1
Heather A. Knutson, David Charbonneau, Drake Deming +1
Eclipsing planetary systems give us an important window on extrasolar planet atmospheres. By measuring the depth of the secondary eclipse, when the planet moves behind the star, we…
3.8-Micron Photometry During the Secondary Eclipse of the Extrasolar Planet HD 209458b
Drake Deming, L. Jeremy Richardson, Joseph Harrington
We report infrared photometry of the extrasolar planet HD 209458b during the time of secondary eclipse (planet passing behind the star). Observations were acquired during two secon…
A Spectrum of an Extrasolar Planet
L. Jeremy Richardson, Drake Deming, Karen Horning +2
Of the over 200 known extrasolar planets, 14 exhibit transits in front of their parent stars as seen from Earth. Spectroscopic observations of the transiting planets can probe the…
The phase-dependent Infrared brightness of the extrasolar planet upsilon Andromedae b
J. Harrington, B. Hansen, S. Luszcz +5
The star upsilon Andromeda is orbited by three known planets, the innermost of which has an orbital period of 4.617 days and a mass at least 0.69 that of Jupiter. This planet is cl…
A Spitzer Infrared Radius for the Transiting Extrasolar Planet HD209458b
L. Jeremy Richardson, Joseph Harrington, Sara Seager +1
We have measured the infrared transit of the extrasolar planet HD209458b using the Spitzer Space Telescope. We observed two primary eclipse events (one partial and one complete tra…
