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.
Long-Term Stability of Planets in Binary Systems
A simple question of celestial mechanics is investigated: in what regions of phase space near a binary system can planets persist for long times? The planets are taken to be test particles moving in
The Pan-STARRS1 Surveys
Pan-STARRS1 has carried out a set of distinct synoptic imaging sky surveys including the $3\pi$ Steradian Survey and the Medium Deep Survey in 5 bands ($grizy_{P1}$). The mean 5$\sigma$ point source
Architecture and Dynamics of Kepler's Candidate Multiple Transiting Planet Systems
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
A super-Earth transiting a nearby low-mass star
Observations of the transiting planet GJ’1214b are reported, finding that the planetary mass and radius are consistent with a composition of primarily water enshrouded by a hydrogen–helium envelope that is only 0.05% of the mass of the planet.
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
The Size Distribution of Trans-Neptunian Bodies*
We search 0.02 deg 2 of the invariable plane for trans-Neptunian objects (TNOs) 25 AU or more distant using the Advanced Camera for Surveys (ACS) aboard the Hubble Space Telescope. With 22 ks per
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.
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
