We report the discovery and confirmation of a transiting circumbinary planet (PH1b) around KIC 4862625, an eclipsing binary in the Kepler field. The planet was discovered by volunteers searching the first six Quarters of publicly available Kepler data as part of the Planet Hunters citizen science project. Transits of the planet across the larger and brighter of the eclipsing stars are detectable by visual inspection every ~137 days, with seven transits identified in Quarters 1-11. The physical… Expand
Kepler 453 b - The 10th Kepler transiting circumbinary planet
We present the discovery of Kepler-453 b, a 6.2 R⊕ planet in a low-eccentricity, 240.5 day orbit about an eclipsing binary. The binary itself consists of a 0.94 and 0.195 M⊙ pair of stars with anExpand
Planet Hunters Tess I: TOI 813, a subgiant hosting a transiting Saturn-sized planet on an 84-day orbit
We report on the discovery and validation of TOI 813 b (TIC55525572b), a transiting exoplanet identified by citizen scientists in data from NASA's Transiting Exoplanet Survey Satellite (TESS) and theExpand
Kepler-1647b: The Largest and Longest-period Kepler Transiting Circumbinary Planet
We report the discovery of a new Kepler transiting circumbinary planet (CBP). This latest addition to the still-small family of CBPs defies the current trend of known short-period planets orbitingExpand
No circumbinary planets transiting the tightest Kepler binaries – a possible fingerprint of a third star
The Kepler mission has yielded the discovery of eight circumbinary systems, all found around eclipsing binaries with periods greater than 7 d. This is longer than the typical eclipsing binary periodExpand
Planet Hunters. VIII. Characterization of 41 Long-Period Exoplanet Candidates from Kepler Archival Data
The census of exoplanets is incomplete for orbital distances larger than 1 AU. Here, we present 41 long-period planet candidates in 38 systems identified by Planet Hunters based on Kepler archivalExpand
TOI-1338: TESS’ First Transiting Circumbinary Planet
We report the detection of the first circumbinary planet found by TESS. The target, a known eclipsing binary, was observed in sectors 1 through 12 at 30-minute cadence and in sectors 4 through 12 atExpand
Predicting a third planet in the Kepler-47 circumbinary system
We have studied the possibility that a third circumbinary planet in the Kepler-47 planetary system be the source of the single unexplained transiting event reported during the discovery of theseExpand
Planet Hunters. V. A Confirmed Jupiter-size Planet in the Habitable Zone and 42 Planet Candidates from the Kepler Archive Data
We report the latest Planet Hunter results, including PH2 b, a Jupiter-size (R PL = 10.12 ? 0.56 R ?) planet orbiting in the habitable zone of a solar-type star. PH2 b was elevated from candidateExpand
On the abundance of circumbinary planets
Circumbinary planets are bodies that orbit both components in a binary star system. This thesis focuses on transits of these planets, which with the aid of the Kepler space telescope have recentlyExpand
Transits of Planets with Small Intervals in Circumbinary Systems
Transit times around single stars can be described well by a linear ephemeris. However, transit times in circumbinary systems are influenced both by the gravitational perturbations and the orbitalExpand


Transiting circumbinary planets Kepler-34 b and Kepler-35 b
The observed rate of circumbinary planets in this sample implies that more than ∼1% of close binary stars have giant planets in nearly coplanar orbits, yielding a Galactic population of at least several million. Expand
The Neptune-sized Circumbinary Planet Kepler-38b
We discuss the discovery and characterization of the circumbinary planet Kepler-38b. The stellar binary is single-lined, with a period of 18.8 days, and consists of a moderately evolved main-sequenceExpand
Kepler-47: A Transiting Circumbinary Multiplanet System
The detection of Kepler-47 establishes that close binary stars can host complete planetary systems, and reveals two small planets orbiting a pair of two low-mass stars. Expand
Kepler-16: A Transiting Circumbinary Planet
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. Expand
The California Planet Survey. I. Four New Giant Exoplanets
We present precise Doppler measurements of four stars obtained during the past decade at Keck Observatory by the California Planet Survey (CPS). These stars, namely, HD 34445, HD 126614, HD 13931,Expand
We present the results from a search of data from the first 33.5 days of the Kepler science mission (Quarter 1) for exoplanet transits by the Planet Hunters citizen science project. Planet HuntersExpand
Discovery of a planet orbiting a binary star system from gravitational microlensing
The properties of the recently discovered extrasolar planets were not anticipated by theoretical work on the formation of planetary systems, most models for which were developed to explain our SolarExpand
Multiplicity in transiting planet-host stars - A lucky imaging study of Kepler candidates
Context. In the exoplanetary era, the Kepler spacecraft is causing a revolution by discovering thousands of new planet candidates. However, a follow-up program is needed to reject false candidatesExpand
Planet Hunters: the first two planet candidates identified by the public using the Kepler public archive data
