Kepler Planet-Detection Mission: Introduction and First Results
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.
Accurate masses and radii of normal stars: modern results and applications
This article presents and discusses a critical compilation of accurate, fundamental determinations of stellar masses and radii. We have identified 95 detached binary systems containing 190 stars (94…
THE FALSE POSITIVE RATE OF KEPLER AND THE OCCURRENCE OF PLANETS
The Kepler mission is uniquely suited to study the frequencies of extrasolar planets. This goal requires knowledge of the incidence of false positives such as eclipsing binaries in the background of…
Characteristics of planetary candidates observed by Kepler, II: Analysis of the first four months of data
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…
On the Use of Empirical Bolometric Corrections for Stars
- G. Torres
- 23 August 2010
When making use of tabulations of empirical bolometric corrections for stars (BC V ), a commonly overlooked fact is that while the zero point is arbitrary, the bolometric magnitude of the Sun (M…
A closely packed system of low-mass, low-density planets transiting Kepler-11
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.
Detection of Thermal Emission from an Extrasolar Planet
We present Spitzer Space Telescope infrared photometric time series of the transiting extrasolar planet system TrES-1. The data span a predicted time of secondary eclipse, corresponding to 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…
Improved Parameters for Extrasolar Transiting Planets
We present refined values for the physical parameters of transiting exoplanets, based on a self-consistent and uniform analysis of transit light curves and the observable properties of the host…
HD 80606 b, a planet on an extremely elongated orbit
We report the detection of a planetary companion orbiting the solar-type star HD 80606, the brighter component of a wide binary with a projected separation of about 2000 AU. Using high-signal…
