  • Kramon, Eric; Posner, Daniel N. (John Hopkins University Press, 2011-04)
    On 4 August 2010, Kenyans voted to adopt a new constitution, culminating a process that began as part of a resolution to the violent conflict that followed the December 2007 elections. By reducing executive power, devolving ...
  • Seager, Sara (IOP Publishing, 2011-09)
    We present the discovery of a hot Jupiter transiting an F star in a close visual (0[" over .]3 sky projected angular separation) binary system. The dilution of the host star's light by the nearly equal magnitude stellar ...
  • Demory, Brice-Olivier (IOP Publishing, 2011-11)
    We report the discovery of Kepler-15b (KOI-128), a new transiting exoplanet detected by NASA's Kepler mission. The transit signal with a period of 4.94 days was detected in the quarter 1 (Q1) Kepler photometry. For the ...
  • Winn, Joshua Nathan (American Association for the Advancement of Science (AAAS), 2011-09)
    We report the detection of a planet whose orbit surrounds a pair of low-mass stars. Data from the Kepler spacecraft reveal transits of the planet across both stars, in addition to the mutual eclipses of the stars, giving ...
  • Seager, Sara; Demory, Brice-Olivier; Winn, Joshua Nathan (Institute of Physics Publishing, 2011-11)
    We report the detection of three transiting planets around a Sun-like star, which we designate Kepler-18. The transit signals were detected in photometric data from the Kepler satellite, and were confirmed to arise from ...
  • Rogers, Leslie Anne; Seager, Sara (IOP Publishing, 2012-03)
    We present the discovery of the Kepler-20 planetary system, which we initially identified through the detection of five distinct periodic transit signals in the Kepler light curve of the host star 2MASS J19104752+4220194. ...
  • Demory, Brice-Olivier; Carter, Joshua Adam (IOP Publishing, 2012-01)
    A search of the time-series photometry from NASA's Kepler spacecraft reveals a transiting planet candidate orbiting the 11th magnitude G5 dwarf KIC 10593626 with a period of 290 days. The characteristics of the host star ...
  • Deck, Katherine M.; Rogers, Leslie A.; Winn, Joshua Nathan (American Association for the Advancement of Science (AAAS), 2012-06)
    In the solar system, the planets’ compositions vary with orbital distance, with rocky planets in close orbits and lower-density gas giants in wider orbits. The detection of close-in giant planets around other stars was the ...
  • Orosz, Jerome A.; Welsh, William F.; Carter, Joshua Adam; Fabrycky, Daniel C.; Cochran, William D.; Endl, Michael; Ford, Eric B.; Haghighipour, Nader; MacQueen, Phillip J.; Mazeh, Tsevi; Sanchis Ojeda, Roberto; Short, Donald R.; Torres, Guillermo; Agol, Eric; Buchhave, Lars A.; Doyle, Laurance R.; Isaacson, Howard; Lissauer, Jack J.; Marcy, Geoffrey W.; Shporer, Avi; Windmiller, Gur; Barclay, Thomas; Boss, Alan P.; Clarke, Bruce D.; Fortney, Jonathan; Geary, John C.; Holman, Matthew J.; Huber, Daniel; Jenkins, Jon M.; Kinemuchi, Karen; Kruse, Ethan; Ragozzine, Darin; Sasselov, Dimitar; Still, Martin; Tenenbaum, Peter; Uddin, Kamal; Winn, Joshua Nathan; Koch, David G.; Borucki, William J. (American Association for the Advancement of Science (AAAS), 2012-08)
    We report the detection of Kepler-47, a system consisting of two planets orbiting around an eclipsing pair of stars. The inner and outer planets have radii 3.0 and 4.6 times that of Earth, respectively. The binary star ...
  • Sanchis Ojeda, Roberto; Winn, Joshua Nathan (American Association for the Advancement of Science (AAAS), 2013-05)
    We present the detection of five planets—Kepler-62b, c, d, e, and f—of size 1.31, 0.54, 1.95, 1.61 and 1.41 Earth radii (R[subscript ⊕]), orbiting a K2V star at periods of 5.7, 12.4, 18.2, 122.4, and 267.3 days, respectively. ...
  • Marcy, Geoffrey W.; Howard, Andrew W.; Isaacson, Howard; Johnson, John Asher; Torres, Guillermo; Albrecht, Simon H.; Campante, T. L.; Chaplin, William J.; Davies, Guy R.; Lund, Mikkel N.; Carter, Joshua Adam; Dawson, Rebekah I.; Buchhave, Lars A.; Everett, Mark E.; Fischer, Debra A.; Geary, John C.; Gilliland, Ronald L.; Horch, Elliott P.; Howell, Steve B.; Latham, David W.; Sanchis Ojeda, Roberto; Winn, Joshua Nathan (IOP Publishing, 2013-09)
    We present the discovery and characterization of a giant planet orbiting the young Sun-like star Kepler-63 (KOI-63, m [subscript Kp] = 11.6, T [subscript eff] = 5576 K, M [star] = 0.98 M [subscript ☉]). The planet transits ...
  • Prsa, Andrej; Batalha, Natalie M.; Slawson, Robert W.; Doyle, Laurance R.; Welsh, William F.; Orosz, Jerome A.; Seager, Sara; Rucker, Michael; Mjaseth, Kimberly; Engle, Scott G.; Conroy, Kyle; Jenkins, Jon; Caldwell, Douglas A.; Koch, David; Borucki, William J. (IOP Publishing, 2011-02)
    The Kepler space mission is devoted to finding Earth-size planets orbiting other stars in their habitable zones. Its large, 105 deg[superscript 2] field of view features over 156,000 stars that are observed continuously ...
  • Seager, Sara (IOP Publishing, 2011-02)
    NASA's Kepler Mission uses transit photometry to determine the frequency of Earth-size planets in or near the habitable zone of Sun-like stars. The mission reached a milestone toward meeting that goal: the discovery of its ...
  • Keten, Sinan; Buehler, Markus J. (American Physical Society, 2009-03)
    A Reply to the Comment by Dmitrii E. Makarov.
  • Noguchi, Yasushi; Nishikata, Natsumi; Shikata, Nahoko; Kimura, Yoshiko; Aleman, Jose O.; Young, Jamey D.; Koyama, Naoto; Kelleher, Joanne Keene; Takahashi, Michio; Stephanopoulos, Gregory (Public Library of Science, 2010-08)
    Background Although dietary ketogenic essential amino acid (KAA) content modifies accumulation of hepatic lipids, the molecular interactions between KAAs and lipid metabolism are yet to be fully elucidated. Methodolo ...
  • Little, Danny Greg; Miller, Robert C. (Springer Netherlands, 2008-10)
    Keyword programming is a novel technique for reducing the need to remember details of programming language syntax and APIs, by translating a small number of unordered keywords provided by the user into a valid expression. ...
  • Kronheimer, P. B.; Mrowka, Tomasz S. (Springer-Verlag, 2011-11)
    We prove that a knot is the unknot if and only if its reduced Khovanov cohomology has rank 1. The proof has two steps. We show first that there is a spectral sequence beginning with the reduced Khovanov cohomology and ...
  • Samuels, Richard J. (Lynne Rienner Publishers, 2010-10)
    Introduction: History is filled with political abductions, incidents in which individuals are kidnapped and held hostage by hostile groups or states to gain leverage or legitimacy for their cause.1 Such episodes have been ...
