Alien Maps of an Ocean-Bearing World
(IOP Publishing, 2009-07)When Earth-mass extrasolar planets first become detectable, one challenge will be to determine which of these worlds harbor liquid water, a widely used criterion for habitability. Some of the first observations of these ... -
Earth as an Extrasolar Planet: Earth Model Validation Using EPOXI Earth Observations
(Mary Ann Liebert, Inc., 2011-01)The EPOXI Discovery Mission of Opportunity reused the Deep Impact flyby spacecraft to obtain spatially and temporally resolved visible photometric and moderate resolution near-infrared (NIR) spectroscopic observations of ... -
Properties of an Earth-Like Planet Orbiting a Sun-Like Star: Earth Observed by the EPOXI Mission
(Mary Ann Liebert, Inc., 2011-11)NASA's EPOXI mission observed the disc-integrated Earth and Moon to test techniques for reconnoitering extrasolar terrestrial planets, using the Deep Impact flyby spacecraft to observe Earth at the beginning and end of ... -
Rotational Variability of Earth's Polar Regions: Implications for Detecting Snowball Planets
(IOP Publishing, 2011-03)We have obtained the first time-resolved, disk-integrated observations of Earth's poles with the Deep Impact spacecraft as part of the EPOXI mission of opportunity. These data mimic what we will see when we point next-generation ... -
A Search for a Sub-Earth-Sized Companion to GJ 436 and a Novel Method to Calibrate Warm Spitzer IRAC Observations
(University of Chicago Press, The, 2010-10)We discovered evidence for a possible additional 0.75 transiting planet in the NASA EPOXI observations of the known M dwarf exoplanetary system GJ 436. Based on an ephemeris determined from the EPOXI data, we predicted a ... -
A Search for Additional Planets in Five of the Exoplanetary Systems Studied by the Nasa Epoxi Mission
(IOP Publishing, 2011-04)We present time series photometry and constraints on additional planets in five of the exoplanetary systems studied by the EPOCh (Extrasolar Planet Observation and Characterization) component of the NASA EPOXI mission: ... -
A Search for Additional Planets in the Nasa Epoxi Observations of the Exoplanet System Gj 436
(IOP Publishing, 2010-05)We present time series photometry of the M dwarf transiting exoplanet system GJ 436 obtained with the Extrasolar Planet Observation and Characterization (EPOCh) component of the NASA EPOXI mission. We conduct a search of ... -
Studying the atmosphere of the exoplanet HAT-P-7b via secondary eclipse measurements with EPOXI, Spitzer and Kepler
(Institute of Physics, 2010-01)The highly irradiated transiting exoplanet, HAT-P-7b, currently provides one of the best opportunities for studying planetary emission in the optical and infrared wavelengths. We observe six near-consecutive secondary ... -
System Parameters, Transit Times, and Secondary Eclipse Constraints of the Exoplanet Systems Hat-P-4, Tres-2, Tres-3, and Wasp-3 from the Nasa EPOXI Mission of Opportunity
(IOP Publishing, 2010-12)As part of the NASA EPOXI Mission of Opportunity, we observed seven known transiting extrasolar planet systems in order to construct time series photometry of extremely high phase coverage and precision. Here we present ...
