The California-Kepler Survey. III. A Gap in the Radius Distribution of Small Planets*
- B. Fulton, E. Petigura, +10 authors L. Hirsch
- Physics
- 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… Expand
Giant Planet Occurrence in the Stellar Mass-Metallicity Plane
- J. Johnson, K. Aller, A. Howard, J. Crepp
- Physics
- 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… Expand
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… Expand
THE FREQUENCY OF HOT JUPITERS ORBITING NEARBY SOLAR-TYPE STARS*
- J. Wright, G. W. Marcy, A. Howard, J. Johnson, T. Morton, D. Fischer
- 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… Expand
Supernova SN 2011fe from an exploding carbon–oxygen white dwarf star
- P. Nugent, M. Sullivan, +36 authors D. Poznanski
- Physics, Medicine
- Nature
- 27 October 2011
Type Ia supernovae have been used empirically as ‘standard candles’ to demonstrate the acceleration of the expansion of the Universe even though fundamental details, such as the nature of their… Expand
A CORRELATION BETWEEN STELLAR ACTIVITY AND HOT JUPITER EMISSION SPECTRA
- H. Knutson, A. Howard, H. Isaacson
- Physics
- 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… Expand
PLANETARY CANDIDATES OBSERVED BY KEPLER. III. ANALYSIS OF THE FIRST 16 MONTHS OF DATA
- N. Batalha, J. Rowe, +111 authors G. S. University
- Physics
- 27 February 2012
New transiting planet candidates are identified in 16 months (2009 May-2010 September) of data from the Kepler spacecraft. Nearly 5000 periodic transit-like signals are vetted against astrophysical… Expand
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… Expand
The Exoplanet Orbit Database
- J. Wright, O. Fakhouri, +8 authors N. Piskunov
- 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… Expand
FRIENDS OF HOT JUPITERS. I. A RADIAL VELOCITY SEARCH FOR MASSIVE, LONG-PERIOD COMPANIONS TO CLOSE-IN GAS GIANT PLANETS
- H. Knutson, B. Fulton, +10 authors P. Muirhead
- Physics
- 10 December 2013
In this paper we search for distant massive companions to known transiting hot Jupiters that may have influenced the dynamical evolution of these systems. We present new radial velocity observations… Expand
