KEPLER: A Unified Model for Knowledge Embedding and Pre-trained Language Representation [PDF]

open access: yesTransactions 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 ...

Exoplanet Characterization by Proxy: a Transiting 2.15 R_Earth Planet Near the Habitable Zone of the Late K dwarf Kepler-61 [PDF]

open access: bronze, 2013
We present the validation and characterization of Kepler-61b: a 2.15 R_Earth planet orbiting near the inner edge of the habitable zone of a low-mass star.

Near Mean-motion Resonances in the Systems Observed by Kepler: Affected by Mass Accretion and Type I Migration [PDF]

open access: bronze, 2017
The Kepler mission has released over 4496 planetary candidates, among which 3483 planets have been confirmed as of April 2017. The statistical results of the planets show that there are two peaks around 1.5 and 2.0 in the distribution of orbital period ...

Solar-Like Oscillators in the Kepler Era: A Review

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Many late-type stars across the Milky Way exhibit observable pulsations similar to our Sun that open up a window into stellar interiors. The NASA Kepler mission, a space-based photometric telescope, measured the micro-magnitude luminosity fluctuations ...

Circumbinary Habitable Zones in the Presence of a Giant Planet

open access: yesFrontiers in Astronomy and Space Sciences, 2021
Determining habitable zones in binary star systems can be a challenging task due to the combination of perturbed planetary orbits and varying stellar irradiation conditions.

An Improved Algorithm For The Solution of Kepler‘s Equation For An Elliptical Orbit [PDF]

open access: yesEngineering and Technology Journal, 2010
In this paper, a root finding method due to iterative method is used first to thesolution of Kepler's equation for an elliptical orbit. Then the extrapolationtechnique in the form of Aitken D2 - acceleration is applied to improve theconvergence of the ...

Investigating the Variation of Selected Kepler Objects Mid-Transit Times

open access: yesJournal of Advanced Research in Natural and Applied Sciences, 2023
We derived minima times from the transit curves of star-planet systems, Kepler-412, Kepler-422, Kepler-427 ve Kepler-435 observed by Kepler space telescope, using the Kwee - van Woerden method and Gauss function fitting.

Improved parameters of seven Kepler giant companions characterized with SOPHIE and HARPS-N [PDF]

open access: yes, 2015
Radial-velocity observations of Kepler candidates obtained with the SOPHIE and HARPS-N spectrographs have permitted unveiling the nature of the five giant planets Kepler-41b, Kepler-43b, Kepler-44b, Kepler-74b, and Kepler-75b, the massive companion ...

Confirming Resonance in Three Transiting Systems

open access: yesThe Astronomical Journal, 2023
Although resonant planets have orbital periods near commensurability, resonance is also dictated by other factors, such as the planets’ eccentricities and masses, and therefore must be confirmed through a study of the system’s dynamics.
