K2-111: an old system with two planets in near-resonance
This paper reports on the detailed characterization of the K2-111 planetary system with K2, WASP, and ASAS-SN photometry, as well as high-resolution...
K2-140b and K2-180b - Characterization of a hot Jupiter and a mini-Neptune from the K2 mission
We report the independent discovery and characterization of two K2 planets: K2-180b, a mini-Neptune-sized planet in an 8.9-d orbit transiting a V = 12.6 mag...
K2-141 b. A 5-M⊕ super-Earth transiting a K7 V star every 6.7 h
We report on the discovery of K2-141 b (EPIC 246393474 b), an ultra-short-period super-Earth on a 6.7 h orbit transiting an active K7 V star based on data from...
K2-155: A Bright Metal-poor M Dwarf with Three Transiting Super-Earths
We report on the discovery of three transiting super-Earths around K2-155 (EPIC 210897587), a relatively bright early M dwarf (V = 12.81 mag) observed during...
K2-264: a transiting multiplanet system in the Praesepe open cluster
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...
K2-280 b - a low density warm sub-Saturn around a mildly evolved star
We present an independent discovery and detailed characterization of K2-280 b, a transiting low density warm sub-Saturn in a 19.9-d moderately eccentric orbit...
Kepler Object of Interest Network. I. First results combining ground- and space-based observations of Kepler systems with transit timing variations
During its four years of photometric observations, the Kepler space telescope detected thousands of exoplanets and exoplanet candidates. One of Kepler's...
Kepler Object of Interest Network. II. Photodynamical modelling of Kepler-9 over 8 years of transit observations
Context. The Kepler Object of Interest Network (KOINet) is a multi-site network of telescopes around the globe organised to follow up transiting planet...
Observations of very low-mass stars with Kepler represent an excellent opportunity to search for planetary transits and to characterize optical photometric...
