Modeling Kepler transit light curves as false positives: Rejection of blend scenarios for Kepler-9, and validation of Kepler-9d, a super-Earth-size planet in a multiple system
Guillermo Torres, François Fressin, Natalie M. Batalha +26
Light curves from the Kepler Mission contain valuable information on the nature of the phenomena producing the transit-like signals. To assist in exploring the possibility that the…
Photometric Variability in Kepler Target Stars. II. An Overview of Amplitude, Periodicity, and Rotation in First Quarter Data
Gibor Basri, Lucianne M. Walkowicz, Natalie Batalha +10
We provide an overview of stellar variability in the first quarter of data from the Kepler mission. The intent of this paper is to examine the entire sample of over 150,000 target…
White-light flares on cool stars in the Kepler Quarter 1 Data
Lucianne M. Walkowicz, Gibor Basri, Natalie Batalha +11
We present the results of a search for white light flares on the ~23,000 cool dwarfs in the Kepler Quarter 1 long cadence data. We have identified 373 flaring stars, some of which…
Characteristics of Kepler Planetary Candidates Based on the First Data Set: The Majority are Found to be Neptune-Size and Smaller
William J. Borucki
In the spring of 2009, the Kepler Mission commenced high-precision photometry on nearly 156,000 stars to determine the frequency and characteristics of small exoplanets, conduct a…
Kepler Eclipsing Binary Stars. I. Catalog and Principal Characterization of 1879 Eclipsing Binaries in the First Data Release
Andrej Prsa, Natalie M. Batalha, Robert W. Slawson +12
The Kepler space mission is devoted to finding Earth-size planets in habitable zones orbiting other stars. Its large, 105-deg field-of-view features over 156,000 stars that are obs…
Five Kepler target stars that show multiple transiting exoplanet candidates
Jason H. Steffen, Natalie M. Batalha, William J. Borucki +27
We present and discuss five candidate exoplanetary systems identified with the Kepler spacecraft. These five systems show transits from multiple exoplanet candidates. Should these…
Kepler Observations of Transiting Hot Compact Objects
Jason F. Rowe, William J. Borucki, David Koch +18
Kepler photometry has revealed two unusual transiting companions orbiting an early A-star and a late B-star. In both cases the occultation of the companion is deeper than the trans…
Kepler Mission Design, Realized Photometric Performance, and Early Science
David G. Koch, William J. Borucki, Gibor Basri +44
The Kepler Mission, launched on Mar 6, 2009 was designed with the explicit capability to detect Earth-size planets in the habitable zone of solar-like stars using the transit photo…
Discovery of the Transiting Planet Kepler-5b
David G. Koch, William J. Borucki, Jason F. Rowe +18
We present 44 days of high duty cycle, ultra precise photometry of the 13th magnitude star Kepler-5 (KIC 8191672, Teff=6300 K, logg=4.1), which exhibits periodic transits with a de…
Kepler-4b: Hot Neptune-Like Planet of a G0 Star Near Main-Sequence Turnoff
William J. Borucki, Davig G. Koch, Timothy M. Brown +16
Early time-series photometry from NASA's Kepler spacecraft has revealed a planet transiting the star we term Kepler-4, at RA = 19h02m27.68s, Dec = +50:08:08.7. The planet has an or…
Kepler Science Operations
Michael R. Haas, Natalie M. Batalha, Steve T. Bryson +13
Kepler's primary mission is a search for earth-size exoplanets in the habitable zone of late-type stars using the transit method. To effectively accomplish this mission, Kepler orb…
Discovery and Rossiter-McLaughlin Effect of Exoplanet Kepler-8b
Jon M. Jenkins, William J. Borucki, David G. Koch +50
We report the discovery and the Rossiter-McLaughlin effect of Kepler-8b, a transiting planet identified by the NASA Kepler Mission. Kepler photometry and Keck-HIRES radial velociti…
Photometric Variability in Kepler Target Stars: The Sun Among Stars -- A First Look
Gibor Basri, Lucianne M. Walkowicz, Natalie Batalha +10
The Kepler mission provides an exciting opportunity to study the lightcurves of stars with unprecedented precision and continuity of coverage. This is the first look at a large sam…
Pre-Spectroscopic False Positive Elimination of Kepler Planet Candidates
N. M. Batalha, J. F. Rowe, R. L. Gilliland +11
Ten days of commissioning data (Quarter 0) and thirty-three days of science data (Quarter 1) yield instrumental flux timeseries of ~150,000 stars that were combed for transit event…
The Kepler Follow-up Observation Program
Thomas N. Gautier, Natalie M. Batalha, William J. Borucki +14
The Kepler Mission was launched on March 6, 2009 to perform a photometric survey of more than 100,000 dwarf stars to search for terrestrial-size planets with the transit technique.…
Selection, Prioritization, and Characteristics of Kepler Target Stars
N. M. Batalha, W. J. Borucki, D. G. Koch +8
The Kepler Mission began its 3.5-year photometric monitoring campaign in May 2009 on a select group of approximately 150,000 stars. The stars were chosen from the ~half million in…
