A dearth of small particles in the transiting material around the white dwarf WD 1145+017
S. Xu, S. Rappaport, R. van Lieshout +35
White dwarf WD 1145+017 is orbited by several clouds of dust, possibly emanating from actively disintegrating bodies. These dust clouds reveal themselves through deep, broad, and e…
Exterior Companions to Hot Jupiters Orbiting Cool Stars are Coplanar
Juliette C. Becker, Andrew Vanderburg, Fred C. Adams +2
The existence of hot Jupiters has challenged theories of planetary formation since the first extrasolar planets were detected. Giant planets are generally believed to form far from…
The discovery and mass measurement of a new ultra-short-period planet: EPIC~228732031b
Fei Dai, Joshua N. Winn, Davide Gandolfi +51
We report the discovery of a new ultra-short-period planet and summarize the properties of all such planets for which the mass and radius have been measured. The new planet, EPIC~2…
Precise Masses in the WASP-47 System
Andrew Vanderburg, Juliette C. Becker, Lars A. Buchhave +32
We present precise radial velocity observations of WASP-47, a star known to host a hot Jupiter, a distant Jovian companion, and, uniquely, two additional transiting planets in shor…
Zodiacal Exoplanets in Time (ZEIT) V: A Uniform Search for Transiting Planets in Young Clusters Observed by K2
Aaron C. Rizzuto, Andrew W. Mann, Andrew Vanderburg +2
Detection of transiting exoplanets around young stars is more difficult than for older systems due to increased stellar variability. Nine young open cluster planets have been found…
Three statistically validated K2 transiting warm Jupiter exoplanets confirmed as low-mass stars
Avi Shporer, George Zhou, Andrew Vanderburg +11
We have identified three K2 transiting star-planet systems, K2-51 (EPIC 202900527), K2-67 (EPIC 206155547), and K2-76 (EPIC 206432863), as stellar binaries with low-mass stellar se…
K2-114b and K2-115b: Two Transiting Warm Jupiters
Avi Shporer, George Zhou, Benjamin J. Fulton +22
We report the first results from a search for transiting warm Jupiter exoplanets - gas giant planets receiving stellar irradiation below about erg s cm, equiva…
Zodiacal Exoplanets in Time (ZEIT) VI: a three-planet system in the Hyades cluster including an Earth-sized planet
Andrew W. Mann, Andrew Vanderburg, Aaron C. Rizzuto +11
Planets in young clusters are powerful probes of the evolution of planetary systems. Here we report the discovery of three planets transiting K2-136 (EPIC 247589423), a late K dwar…
A System of Three Super Earths Transiting the Late K-Dwarf GJ 9827 at Thirty Parsecs
Joseph E. Rodriguez, Andrew Vanderburg, Jason D. Eastman +5
We report the discovery of three small transiting planets orbiting GJ 9827, a bright (K = 7.2) nearby late K-type dwarf star. GJ 9827 hosts a super E…
Likely Transiting Exocomets Detected by Kepler
S. Rappaport, A. Vanderburg, T. Jacobs +8
We present the first good evidence for exocomet transits of a host star in continuum light in data from the Kepler mission. The Kepler star in question, KIC 3542116, is of spectral…
Three's Company: An additional non-transiting super-Earth in the bright HD 3167 system, and masses for all three planets
Jessie L. Christiansen, Andrew Vanderburg, Jennifer Burt +55
HD 3167 is a bright (V = 8.9), nearby K0 star observed by the NASA K2 mission (EPIC 220383386), hosting two small, short-period transiting planets. Here we present the results of a…
Seeing double with K2: Testing re-inflation with two remarkably similar planets around red giant branch stars
Samuel K. Grunblatt, Daniel Huber, Eric Gaidos +15
Despite more than 20 years since the discovery of the first gas giant planet with an anomalously large radius, the mechanism for planet inflation remains unknown. Here, we report t…
WD 1202-024: The Shortest-Period Pre-Cataclysmic Variable
S. Rappaport, A. Vanderburg, L. Nelson +8
Among the 28,000 targeted stars in K2 Field 10 is the white dwarf WD 1202-024 (EPIC 201283111), first noted in the SDSS survey (SDSS 120515.80-024222.7). We have found that this ho…
K2-106, a system containing a metal-rich planet and a planet of lower density
E. W. Guenther, O. Barragan, F. Dai +42
Planets in the mass range from 2 to 15 MEarth are very diverse. Some of them have low densities, while others are very dense. By measuring the masses and radii, the mean densities,…
Weighing in on the masses of retired A stars with asteroseismology: K2 observations of the exoplanet-host star HD 212771
Tiago L. Campante, Dimitri Veras, Thomas S. H. North +12
Doppler-based planet surveys point to an increasing occurrence rate of giant planets with stellar mass. Such surveys rely on evolved stars for a sample of intermediate-mass stars (…
Characterizing K2 Candidate Planetary Systems Orbiting Low-Mass Stars II: Planetary Systems Observed During Campaigns 1-7
Courtney D. Dressing, Andrew Vanderburg, Joshua E. Schlieder +14
We recently used near-infrared spectroscopy to improve the characterization of 76 low-mass stars around which K2 had detected 79 candidate transiting planets. Thirty of these world…
The Kepler-19 system: a thick-envelope super-Earth with two Neptune-mass companions characterized using Radial Velocities and Transit Timing Variations
Luca Malavolta, Luca Borsato, Valentina Granata +36
We report a detailed characterization of the Kepler-19 system. This star was previously known to host a transiting planet with a period of 9.29 days, a radius of 2.2 R and…
