KEPLER: A Unified Model for Knowledge Embedding and Pre-trained Language Representation [PDF]
Transactions of the Association for Computational Linguistics, 2021 Pre-trained language representation models (PLMs) cannot well capture factual knowledge from text. In contrast, knowledge embedding (KE) methods can effectively represent the relational facts in knowledge graphs (KGs) with informative entity embeddings ...

An exomoon survey of 70 cool giant exoplanets and the new candidate Kepler-1708 b-i [PDF]
Nature Astronomy, 2022 Exomoons represent a crucial missing puzzle piece in our efforts to understand extrasolar planetary systems. To address this deficiency, we here describe an exomoon survey of 70 cool, giant transiting exoplanet candidates found by Kepler.

The Gaia–Kepler Stellar Properties Catalog. II. Planet Radius Demographics as a Function of Stellar Mass and Age [PDF]
Astronomical Journal, 2020 Studies of exoplanet demographics require large samples and precise constraints on exoplanet host stars. Using the homogeneous Kepler stellar properties derived using the Gaia Data Release 2 by Berger et al., we recompute Kepler planet radii and incident

Evidence for a Nondichotomous Solution to the Kepler Dichotomy: Mutual Inclinations of Kepler Planetary Systems from Transit Duration Variations [PDF]
Astronomical Journal, 2021 Early analyses of exoplanet statistics from the Kepler mission revealed that a model population of multiplanet systems with low mutual inclinations (∼1°–2°) adequately describes the multiple-transiting systems but underpredicts the number of single ...

Long-period Jovian Tilts the Orbits of Two sub-Neptunes Relative to Stellar Spin Axis in Kepler-129 [PDF]
Astronomical Journal, 2021 We present the discovery of Kepler-129 d ( Pd=7.2−0.3+0.4 yr, msinid=8.3−0.7+1.1MJup , ed=0.15−0.05+0.07 ) based on six years of radial-velocity observations from Keck/HIRES.

The California-Kepler Survey. VII. Precise Planet Radii Leveraging Gaia DR2 Reveal the Stellar Mass Dependence of the Planet Radius Gap [PDF]
Astronomical Journal, 2018 The distribution of planet sizes encodes details of planet formation and evolution. We present the most precise planet size distribution to date based on Gaia parallaxes, Kepler photometry, and spectroscopic temperatures from the California-Kepler Survey.

The California-Kepler Survey. III. A Gap in the Radius Distribution of Small Planets [PDF]
, 2017 The size of a planet is an observable property directly connected to the physics of its formation and evolution. We used precise radius measurements from the California-Kepler Survey to study the size distribution of 2025 Kepler planets in fine detail ...

Kepler-102: Masses and Compositions for a Super-Earth and Sub-Neptune Orbiting an Active Star
The Astronomical Journal, 2023 Radial velocity (RV) measurements of transiting multiplanet systems allow us to understand the densities and compositions of planets unlike those in the solar system. Kepler-102, which consists of five tightly packed transiting planets, is a particularly

On the regularization of the Kepler problem [PDF]
Journal of Symplectic Geometry, 2012 We show that for the Kepler problem the canonical Ligon-Schaaf regularization map can be understood in a straightforward manner as an adaptation of the Moser regularization. In turn this explains the hidden symmetry in a geometric way.

The Evaporation Valley in the Kepler Planets [PDF]
, 2017 A new piece of evidence supporting the photoevaporation-driven evolution model for low-mass, close-in exoplanets was recently presented by the California–Kepler Survey. The radius distribution of the Kepler planets is shown to be bimodal, with a “valley”
