Revisiting the Kepler field with TESS: Improved ephemerides using TESS 2min data [PDF]
, 2021 Up to date planet ephemerides are becoming increasingly important as exoplanet science moves from detecting exoplanets to characterising their architectures and atmospheres in depth. In this work ephemerides are updated for 22 Kepler planets and 4 Kepler planet candidates, constituting all Kepler planets and candidates with sufficient signal to noise ...

KEPLER: A Unified Model for Knowledge Embedding and Pre-trained Language Representation
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 ...

Radial Velocity Observations and Light Curve Noise Modeling Confirm That Kepler-91b is a Giant Planet Orbiting a Giant Star [PDF]
, 2015 Kepler-91b is a rare example of a transiting hot Jupiter around a red giant star, providing the possibility to study the formation and composition of hot Jupiters under different conditions compared to main-sequence stars.

Analysis of Hysteresis in the Regime Transition of Cocurrent Liquid–Gas Flow
steel research international, Volume 93, Issue 12, December 2022., 2022 Fluid dynamics of a cocurrent liquid–gas flow are studied by numerical simulations, and hysteresis in regime transition from bubbly to annular flow and vice versa is explained based on the variation of vortical energy in each phase and history of different enstrophy generation/destruction mechanisms.

Kepler-411: a four-planet system with an active host star [PDF]
A&A 624, A15 (2019), 2019 We present a detailed characterization of the Kepler-411 system (KOI 1781). This system was previously known to host two transiting planets: one with a period of 3 days ($R=2.4R_\oplus$; Kepler-411b) and one with a period of 7.8 days ($R=4.4R_\oplus$; Kepler-411c), as well as a transiting planetary candidate with a 58-day period ($R=3.3R_\oplus$; KOI ...

Gemini-GRACES high-quality spectra of Kepler evolved stars with transiting planets I. Detailed characterization of multi-planet systems Kepler-278 and Kepler-391 [PDF]
A&A 634, A29 (2020), 2019 (abridged) Kepler-278 and Kepler-391 are two of the three evolved stars known to date on the RGB to host multiple short-period transiting planets. Moreover, these planets are among the smallest discovered around RGB stars. Here we present a detailed stellar and planetary characterization of these remarkable systems.

The Kepler-10 planetary system revisited by HARPS-N: A hot rocky world and a solid Neptune-mass planet [PDF]
, 1998 Kepler-10b was the first rocky planet detected by the Kepler satellite and con- firmed with radial velocity follow-up observations from Keck-HIRES. The mass of the planet was measured with a precision of around 30%, which was insufficient to constrain ...

Planetary Candidates Observed by Kepler IV: Planet Sample From Q1-Q8 (22 Months) [PDF]
, 2013 We provide updates to the Kepler planet candidate sample based upon nearly two years of high-precision photometry (i.e., Q1-Q8). From an initial list of nearly 13,400 Threshold Crossing Events (TCEs), 480 new host stars are identified from their flux ...

Accounting Perspectives, Volume 21, Issue 4, Page 581-641, December 2022., 2022 ABSTRACT We investigate the structure and progress of the emergent field of social and environmental accounting (SEA) research by combining social network analysis (SNA) with a systematic literature review based on 461 papers containing 26,872 citations in total. Our approach, which to the best of our knowledge this study is the first to apply, enables
