    • A Search for Additional Planets in Five of the Exoplanetary Systems Studied by the Nasa Epoxi Mission 

      Ballard, Sarah; Christiansen, Jessie L.; Charbonneau, David; Deming, Drake; Holman, Matthew J.; A'Hearn, Michael F.; Wellnitz, Dennis D.; Barry, Richard K.; Kuchner, Marc J.; Livengood, Timothy A.; Hewagama, Tilak; Sunshine, Jessica M.; Hampton, Don L.; Lisse, Carey M.; Seager, Sara; Veverka, Joseph F. (American Astronomical Society, 2011)
      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 

      Ballard, Sarah; Christiansen, Jessie L.; Charbonneau, David; Deming, Drake; Holman, Matthew J.; Fabrycky, Daniel; A'Hearn, Michael F.; Wellnitz, Dennis D.; Barry, Richard K.; Kuchner, Marc J.; Livengood, Timothy A.; Hewagama, Tilak; Sunshine, Jessica M.; Hampton, Don L.; Lisse, Carey M.; Seager, Sara; Veverka, Joseph F. (American Astronomical Society, 2010)
      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 ...

    • Alien Maps of an Ocean-Bearing World 

      Cowan, Nicolas B.; Agol, Eric; Meadows, Victoria S.; Robinson, Tyler; Livengood, Timothy A.; Deming, Drake; Lisse, Carey M.; A'Hearn, Michael F.; Wellnitz, Dennis D.; Seager, Sara; Charbonneau, David (Institute of Physics, 2009)
      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 ...

    • Rotational Variability of Earth's Polar Regions: Implications for Detecting Snowball Planets 

      Cowan, Nicolas B.; Robinson, Tyler; Livengood, Timothy A.; Deming, Drake; Agol, Eric; A'Hearn, Michael F.; Charbonneau, David; Lisse, Carey M.; Meadows, Victoria S.; Seager, Sara; Shields, Aomawa L.; Wellnitz, Dennis D. (American Astronomical Society, 2011)
      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 ...

    • Studying the Atmosphere of the Exoplanet Hat-p-7b Via Secondary Eclipse Measurements Withepoxi,spitzer, Andkepler 

      Christiansen, Jessie L.; Ballard, Sarah; Charbonneau, David; Madhusudhan, Nikku; Seager, Sara; Holman, Matthew J.; Wellnitz, Dennis D.; Deming, Drake; A'Hearn, Michael F.; EPOXI Team; EPOXI Team (American Astronomical Society, 2010)
      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 ...
