Space Warps: I. Crowd-sourcing the Discovery of Gravitational Lenses
Philip J. Marshall, Aprajita Verma, Anupreeta More +20
We describe Space Warps, a novel gravitational lens discovery service that yields samples of high purity and completeness through crowd-sourced visual inspection. Carefully produce…
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-…
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…
Planet Four: Probing Springtime Winds on Mars by Mapping the Southern Polar CO Jet Deposits
K. -Michael Aye, Megan E. Schwamb, Ganna Portyankina +11
The springtime sublimation process of Mars' southern seasonal polar CO ice cap features dark fan-shaped deposits appearing on the top of the thawing ice sheet. The fan material…
Galaxy Zoo: Morphological Classifications for 120,000 Galaxies in HST Legacy Imaging
Kyle W. Willett, Melanie A. Galloway, Steven P. Bamford +18
We present the data release paper for the Galaxy Zoo: Hubble (GZH) project. This is the third phase in a large effort to measure reliable, detailed morphologies of galaxies by usin…
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. 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…
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: New Kepler planet candidates from analysis of quarter 2
Chris J. Lintott, Megan E. Schwamb, Thomas Barclay +17
We present new planet candidates identified in NASA Kepler quarter two public release data by volunteers engaged in the Planet Hunters citizen science project. The two candidates p…
Galaxy Zoo: Mergers - Dynamical Models of Interacting Galaxies
Anthony J. Holincheck, John F. Wallin, Kirk Borne +6
The dynamical history of most merging galaxies is not well understood. Correlations between galaxy interaction and star formation have been found in previous studies, but require t…
Space Warps II. New Gravitational Lens Candidates from the CFHTLS Discovered through Citizen Science
Anupreeta More, Aprajita Verma, Philip J. Marshall +18
We report the discovery of 29 promising (and 59 total) new lens candidates from the CFHT Legacy Survey (CFHTLS) based on about 11 million classifications performed by citizen scien…
