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…
Planet Hunters X: Searching for Nearby Neighbors of 75 Planet and Eclipsing Binary Candidates from the K2 Kepler Extended Mission
Joseph R. Schmitt, Andrei Tokovinin, Ji Wang +22
We present high-resolution observations of a sample of 75 K2 targets from Campaigns 1-3 using speckle interferometry on the Southern Astrophysical Research (SOAR) telescope and ada…
Planet Hunters X. KIC 8462852 - Where's the Flux?
T. S. Boyajian, D. M. LaCourse, S. A. Rappaport +46
Over the duration of the Kepler mission, KIC8462852 was observed to undergo irregularly shaped, aperiodic dips in flux of up to \%. The dipping activity can last for betwe…
The Red Radio Ring: a gravitationally lensed hyperluminous infrared radio galaxy at z=2.553 discovered through citizen science
J. E. Geach, A. More, A. Verma +49
We report the discovery of a gravitationally lensed hyperluminous infrared galaxy (L_IR~10^13 L_sun) with strong radio emission (L_1.4GHz~10^25 W/Hz) at z=2.553. The source was ide…
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. 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…
The History and Environment of a Faded Quasar: Hubble Space Telescope observations of Hanny's Voorwerp and IC 2497
William C. Keel, Chris J. Lintott, Kevin Schawinski +6
We present Hubble Space Telescope imaging and spectroscopy for the extended high-ionization cloud known as Hanny's Voorwerp, near the spiral galaxy IC 2497. WFC3 images show comple…
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: 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…
The Galaxy Zoo survey for giant AGN-ionized clouds: past and present black-hole accretion events
William C. Keel, S. Drew Chojnowski, Vardha N. Bennert +8
Some active galactic nuclei (AGN) are surrounded by extended emission-line regions (EELRs), which trace both the illumination pattern of escaping radiation and its history over the…
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…
