A Probabilistic Approach to Kepler Completeness and Reliability for Exoplanet Occurrence Rates [PDF]
Astronomical Journal, 2019 Exoplanet catalogs produced by surveys suffer from a lack of completeness (not every planet is detected) and less than perfect reliability (not every planet in the catalog is a true planet), particularly near the survey’s detection limit.

Kepler-1661 b: A Neptune-sized Kepler Transiting Circumbinary Planet around a Grazing Eclipsing Binary [PDF]
Astronomical Journal, 2020 We report the discovery of a Neptune-sized ( ) transiting circumbinary planet, Kepler-1661 b, found in the Kepler photometry. The planet has a period of ∼175 days and its orbit precesses with a period of only 35 yr. The precession causes the alignment of

Measuring Transit Signal Recovery in the Kepler Pipeline. IV. Completeness of the DR25 Planet Candidate Catalog [PDF]
Astronomical Journal, 2020 In this work we empirically measure the detection efficiency of the Kepler pipeline used to create the final Kepler threshold crossing event and planet candidate catalogs, a necessary ingredient for occurrence-rate calculations using these lists.

Overview of the LAMOST-Kepler project [PDF]
Research in Astronomy and Astrophysics, 2020 The NASA Kepler mission obtained long-term high-quality photometric observations for a large number of stars in its original field of view from 2009 to 2013. To provide reliable stellar parameters in a homogeneous way, the LAMOST telescope began to carry

Dynamic Covalent Polymer Networks of Silicone Elastomers via Organoborane Lewis-Pairs. [PDF]
ChemistryDCPNs with reversible Lewis pair bonds are reported. Nitrogen‐borane adducts impart dynamic mechanical properties, such as self‐healing and recyclability, to polydimethylsiloxane elastomers. Abstract Dynamic covalent polymer networks (DCPNs) have been developed in recent years to offer distinctive mechanical properties and shape responsiveness in ...

Constraining the Densities of the Three Kepler-289 Planets with Transit Timing Variations
The Astronomical Journal, 2023 Kepler-289 is a three-planet system containing two sub-Neptunes and one cool giant planet orbiting a young, Sun-like star. All three planets exhibit transit timing variations (TTVs), with both adjacent planet pairs having orbital periods close to the 2:1
