Planet Hunters. VIII. Characterization of 41 Long-Period Exoplanet Candidates from Kepler Archival Data
Ji Wang, Debra A. Fischer, Thomas Barclay +30
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…
Building massive compact planetesimal disks from the accretion of pebbles
John Moriarty, Debra Fischer
We present a model in which planetesimal disks are built from the combination of planetesimal formation and accretion of radially drifting pebbles onto existing planetesimals. In t…
Planet Hunters VII. Discovery of a New Low-Mass, Low-Density Planet (PH3 c) Orbiting Kepler-289 with Mass Measurements of Two Additional Planets (PH3 b and d)
Joseph R. Schmitt, Eric Agol, Katherine M. Deck +18
We report the discovery of one newly confirmed planet ( days, ) and mass determinations of two previously validated Kepler planets, Kepler-…
Influence of Stellar Multiplicity On Planet Formation. II. Planets Are Less Common in Multiple-Star Systems with Separations Smaller than 1500 AU
Ji Wang, Debra A. Fischer, Ji-Wei Xie +1
Almost half of the stellar systems in the solar neighborhood are made up of multiple stars. In multiple-star systems, planet formation is under the dynamical influence of stellar c…
Chemistry in an Evolving Protoplanetary Disk: Effects on Terrestrial Planet Composition
John Moriarty, Nikku Madhusudhan, Debra Fischer
The composition of planets is largely determined by the chemical and dynamical evolution of the disk during planetesimal formation and growth. To predict the diversity of exoplanet…
Revealing A Universal Planet-Metallicity Correlation For Planets of Different Sizes Around Solar-Type Stars
Ji Wang, Debra A. Fischer
The metallicity of exoplanet systems serves as a critical diagnostic of planet formation mechanisms. Previous studies have demonstrated the planet-metallicity correlation for large…
Planet Hunters. VI: An Independent Characterization of KOI-351 and Several Long Period Planet Candidates from the Kepler Archival Data
Joseph R. Schmitt, Ji Wang, Debra A. Fischer +29
We report the discovery of 14 new transiting planet candidates in the Kepler field from the Planet Hunters citizen science program. None of these candidates overlapped with Kepler…
Influence of Stellar Multiplicity On Planet Formation. I. Evidence of Suppressed Planet Formation Due to Stellar Companions Within 20 AU and Validation of Four Planets From the Kepler Multiple Planet Candidates
Ji Wang, Ji-Wei Xie, Thomas Barclay +1
The planet occurrence rate for multiple stars is important in two aspects. First, almost half of stellar systems in the solar neighborhood are multiple systems. Second, the compari…
Planet Hunters. V. A Confirmed Jupiter-Size Planet in the Habitable Zone and 42 Planet Candidates from the Kepler Archive Data
Ji Wang, Debra A. Fischer, Thomas Barclay +18
We report the latest Planet Hunter results, including PH2 b, a Jupiter-size (R_PL = 10.12 \pm 0.56 R_E) planet orbiting in the habitable zone of a solar-type star. PH2 b was elevat…
Planet Hunters: A Transiting Circumbinary Planet in a Quadruple Star System
Megan E. Schwamb, Jerome A. Orosz, Joshua A. Carter +17
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 volunt…
Planet Hunters: Assessing the Kepler Inventory of Short Period Planets
Megan E. Schwamb, Chris J. Lintott, Debra A. Fischer +7
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 Hunters: The First Two Planet Candidates Identified by the Public using the Kepler Public Archive Data
Debra Fischer, Megan Schwamb, Kevin Schawinski +28
Planet Hunters is a new citizen science project, designed to engage the public in an exoplanet search using NASA Kepler public release data. In the first month after launch, users…
