The California-Kepler Survey. III. A Gap in the Radius Distribution of Small Planets*
- B. Fulton, E. Petigura, L. Hirsch
- Physics, Geology
- 30 March 2017
The size of a planet is an observable property directly connected to the physics of its formation and evolution. We used precise radius measurements from the California-Kepler Survey to study the…
Characteristics of planetary candidates observed by Kepler, II: Analysis of the first four months of data
- W. Borucki, D. Koch, L. Walkowicz
- 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…
Giant Planet Occurrence in the Stellar Mass-Metallicity Plane
- J. Johnson, K. Aller, A. Howard, J. Crepp
- Physics, Geology
- 18 May 2010
Correlations between stellar properties and the occurrence rate of exoplanets can be used to inform the target selection of future planet-search efforts and provide valuable clues about the…
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…
THE FREQUENCY OF HOT JUPITERS ORBITING NEARBY SOLAR-TYPE STARS*
- J. Wright, G. Marcy, A. Howard, J. Johnson, T. Morton, D. Fischer
- Geology, Physics
- 10 May 2012
We determine the fraction of F, G, and K dwarfs in the solar neighborhood hosting hot Jupiters as measured by the California Planet Survey from the Lick and Keck planet searches. We find the rate to…
Transiting Exoplanet Survey Satellite (TESS)
- G. Ricker, J. Winn, J. Villasenor
- Physics, GeologyAstronomical Telescopes and Instrumentation
- 1 May 2009
The Transiting Exoplanet Survey Satellite (TESS ) will search for planets transiting bright and nearby stars. TESS has been selected by NASA for launch in 2017 as an Astrophysics Explorer mission.…
Supernova SN 2011fe from an exploding carbon–oxygen white dwarf star

TLDR
A CORRELATION BETWEEN STELLAR ACTIVITY AND HOT JUPITER EMISSION SPECTRA
- H. Knutson, A. Howard, H. Isaacson
- Physics, Geology
- 15 April 2010
We present evidence for a correlation between the observed properties of hot Jupiter emission spectra and the activity levels of the host stars measured using Ca II H & K emission lines. We find that…
The Exoplanet Orbit Database
- Jason T. Wright, O. Fakhouri, N. Piskunov
- Geology, Physics
- 27 December 2010
We present a database of well-determined orbital parameters of exoplanets, and their host stars’ properties. This database comprises spectroscopic orbital elements measured for 427 planets orbiting…
THE MASS OF KOI-94d AND A RELATION FOR PLANET RADIUS, MASS, AND INCIDENT FLUX*
We measure the mass of a modestly irradiated giant planet, KOI-94d. We wish to determine whether this planet, which is in a 22 day orbit and receives 2700 times as much incident flux as Jupiter, is…
