Detection and characterization of an ultra-dense sub-Neptune planet orbiting the Sun-like star HD 119130
R. Luque, G. Nowak, E. Pallé +51
We present the discovery and characterization of a new transiting planet from Campaign 17 of the Kepler extended mission K2. HD 119130 b is a warm sub-Neptune on a 17-d orbit aroun…
Constraining the orbit of the planet-hosting binary Boötis: Clues about planetary formation and migration
A. B. Justesen, S. Albrecht
The formation of planets in compact or highly eccentric binaries and the migration of hot Jupiters are two outstanding problems in planet formation. The hot Jupiter Boo Ab orbi…
K2-140b and K2-180b - Characterization of a hot Jupiter and a mini-Neptune from the K2 mission
J. Korth, Sz. Csizmadia, D. Gandolfi +40
We report the independent discovery and characterization of two K2 planets: K2-180b, a mini-Neptune-size planet in an 8.9-day orbit transiting a V = 12.6 mag, metal-poor ([Fe/H] =$…
EPIC 203868608: A low-mass quadruple star system in the Upper Scorpius OB association
Ji Wang, Trevor J. David, Lynne Hillenbrand +3
Young multiple star systems provide excellent testing grounds for theories of star formation and evolution. EPIC 203868608 was previously studied~\citep{David2016} as a triple star…
K2-264: A transiting multi-planet system in the Praesepe open cluster
John H. Livingston, Fei Dai, Teruyuki Hirano +31
Planet host stars with well-constrained ages provide a rare window to the time domain of planet formation and evolution. The NASA K2 mission has enabled the discovery of the vast m…
Detection and Doppler monitoring of EPIC 246471491, a system of four transiting planets smaller than Neptune
E. Palle, G. Nowak, R. Luque +43
The Kepler extended mission, also known as K2, has provided the community with a wealth of planetary candidates that orbit stars typically much brighter than the targets of the ori…
K2-295 b and K2-237 b: two transiting hot Jupiters
A. M. S. Smith, Sz. Csizmadia, D. Gandolfi +32
We report the discovery from K2 of two transiting hot Jupiter systems. K2-295 (observed in Campaign 8) is a K5 dwarf which hosts a planet slightly smaller than Jupiter, orbiting wi…
The orbital eccentricity of small planet systems
Vincent Van Eylen, Simon Albrecht, Xu Huang +8
We determine the orbital eccentricities of individual small Kepler planets, through a combination of asteroseismology and transit light-curve analysis. We are able to constrain the…
Kepler Object of Interest Network II. Photodynamical modelling of Kepler-9 over 8 years of transit observations
J. Freudenthal, C. von Essen, S. Dreizler +14
The Kepler Object of Interest Network (KOINet) is a multi-site network of telescopes around the globe organised to follow up transiting planet candidate KOIs with large transit tim…
44 Validated Planets from K2 Campaign 10
John H. Livingston, Michael Endl, Fei Dai +31
We present 44 validated planets from the 10 observing campaign of the NASA mission, as well as high resolution spectroscopy and speckle imaging follow-up observa…
K2-260 b: a hot Jupiter transiting an F star, and K2-261 b: a warm Saturn around a bright G star
M. C. Johnson, F. Dai, A. B. Justesen +45
We present the discovery and confirmation of two new transiting giant planets from the Kepler extended mission K2. K2-260 b is a hot Jupiter transiting a F6V star in K2 Fi…
EPIC 219217635: A Doubly Eclipsing Quadruple System Containing an Evolved Binary
T. Borkovits, S. Albrecht, S. Rappaport +14
We have discovered a doubly eclipsing, bound, quadruple star system in the field of K2 Campaign 7. EPIC 219217635 is a stellar image with that contains an eclipsing bin…
Na I and H absorption features in the atmosphere of MASCARA-2b/KELT-20b
N. Casasayas-Barris, E. Palle, F. Yan +9
We have used the HARPS-North high resolution spectrograph (=115 000) at TNG to observe one transit of the highly irradiated planet MASCARA-2b/KELT-20b. Using only one…
HD 89345: a bright oscillating star hosting a transiting warm Saturn-sized planet observed by K2
V. Van Eylen, F. Dai, S. Mathur +40
We report the discovery and characterization of HD 89345b (K2-234b; EPIC 248777106b), a Saturn-sized planet orbiting a slightly evolved star. HD 89345 is a bright star ( m…
Super-Earth of 8 Mearth in a 2.2-day orbit around the K5V star K2-216
C. M. Persson, M. Fridlund, O. Barragán +35
The KESPRINT consortium identified K2-216 as a planetary candidate host star in the K2 space mission Campaign 8 field with a transiting super-Earth. The planet has recently been va…
Stellar obliquities and magnetic activities of Planet-Hosting Stars and Eclipsing Binaries based on Transit Chord Correlation
Fei Dai, Joshua N. Winn, Zachory Berta-Thompson +2
The light curve of an eclipsing system shows anomalies whenever the eclipsing body passes in front of active regions on the eclipsed star. In some cases, the pattern of anomalies c…
