- Physics, GeologyScience
- 19 February 2010
The planetary findings derived from the first six weeks of observations with the Kepler mission are summarized, which include the detection of five new exoplanets, which confirm the existence of planets with densities substantially lower than those predicted for gas giant planets.
SDSS-III: MASSIVE SPECTROSCOPIC SURVEYS OF THE DISTANT UNIVERSE, THE MILKY WAY, AND EXTRA-SOLAR PLANETARY SYSTEMS

- 2 February 2011
About one-third of the ∼1200 transiting planet candidates detected in the first four months of Kepler data are members of multiple candidate systems. There are 115 target stars with two candidate…
CHARACTERISTICS OF PLANETARY CANDIDATES OBSERVED BY KEPLER. II. ANALYSIS OF THE FIRST FOUR MONTHS OF DATA

- Physics, Geology
- 2 February 2011
On 2011 February 1 the Kepler mission released data for 156,453 stars observed from the beginning of the science observations on 2009 May 2 through September 16. There are 1235 planetary candidates…

- Physics, GeologyNature
- 1 February 2011
Kepler spacecraft observations of a single Sun-like star are reported that reveal six transiting planets, five with orbital periods between 10 and 47 days and a sixth planet with a longer period, among the smallest for which mass and size have both been measured.
PLANET OCCURRENCE WITHIN 0.25 AU OF SOLAR-TYPE STARS FROM KEPLER
We report the distribution of planets as a function of planet radius, orbital period, and stellar effective temperature for orbital periods less than 50 days around solar-type (GK) stars. These…
Structure and Evolution of Nearby Stars with Planets. II. Physical Properties of ~1000 Cool Stars from the SPOCS Catalog
- G. Takeda, E. Ford, A. Sills, F. Rasio, D. Fischer, J. Valenti
- Physics, Geology
- 11 July 2006
We derive detailed theoretical models for 1074 nearby stars from the SPOCS (Spectroscopic Properties of Cool Stars) Catalog. The California and Carnegie Planet Search has obtained high-quality (R ≃…
KEPLER'S FIRST ROCKY PLANET: KEPLER-10b
- N. Batalha, W. Borucki, A. Gould
- Physics, Geology
- 3 February 2011
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…
Kepler-16: A Transiting Circumbinary Planet
- L. Doyle, J. Carter, D. Fischer
- Physics, GeologyScience
- 15 September 2011
The detection of a planet whose orbit surrounds a pair of low-mass stars, comparable to Saturn in mass and size and on a nearly circular 229-day orbit around its two parent stars, suggests that the planet formed within a circumbinary disk.
Improving the Efficiency of Markov Chain Monte Carlo for Analyzing the Orbits of Extrasolar Planets
- E. Ford
- Physics, Geology
- 29 December 2005
Precise radial velocity measurements have led to the discovery of ~170 extrasolar planetary systems. Understanding the uncertainties in the orbital solutions will become increasingly important as the…
