Detecting Planetary Oblateness in the Era of JWST: A Case Study of Kepler-167e

The Astronomical Journal
Planets may be rotationally flattened, and their oblateness thus provides useful information on their formation and evolution. Here, we develop a new algorithm that can compute the transit light curve due to an oblate planet very efficiently and use it ...

Macau as Method: Recombinant Urbanism in Post‐Socialist China

Asia Pacific Viewpoint, EarlyView.
ABSTRACT In ‘Asia as Method’, Chen Kuan‐Hsing argues for the value of an indigenous inter‐Asian approach to analysing the effects of European imperialism on the countries and citizens of Asia. This article mobilises both Chen's inter‐Asian referencing strategy and the city‐state of Macau to explore Macau's role in China's engagements with global ...

Quantifying the Relationship Between Climatic Conditions and Personal Financial and Health Well‐Being

Oxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT We address an important research gap by quantifying the association between weather conditions (sunshine, rainfall, temperature anomalies) and individual financial, mental and physical health self‐assessments. We compile a unique dataset of >400,000$$ >\mathrm{400,000} $$ observations (1991–2018) by matching individual‐level data (covering 380

A JWST Transit of a Jupiter Analog. I. Constraints on the Oblateness of Kepler-167 e

The Astronomical Journal
In 2024 October, JWST observed a transit of Kepler-167 e, a Jupiter-analog planet on a 1000+ day orbit. These observations, recorded over a long baseline of nearly 60 hr, were designed to search for signatures of planetary oblateness and/or exomoons ...

Cretaceous Spatiotemporal Variations in Tectonic Shortening Directions in the Longmen Shan Tectonic Belt and Geodynamic Implications: Constraints From AMS Fabrics and Crustal Rotation in the Western Sichuan Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract As a major tectonic boundary along the eastern margin of the Tibetan Plateau, the Longmen Shan tectonic belt (LMSTB) underwent pronounced crustal shortening and thickening during the Cretaceous. However, the spatiotemporal evolution of Cretaceous shortening and the boundary's response to far‐field tectonic forcing remain incompletely resolved.

A General, Differentiable Transit Model for Ellipsoidal Occulters: Derivation, Application, and Forecast of Planetary Oblateness and Obliquity Constraints with JWST

The Astrophysical Journal
Increasingly precise space-based photometry uncovers higher-order effects in transits, eclipses, and phase curves that can be used to characterize exoplanets in novel ways.

Insights on Lightning‐Induced Remanent Magnetization From High‐Current Impulse Experiments

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Lightning strikes generate intense transient magnetic fields capable of inducing strong and complex remanent magnetizations in rocks, potentially overprinting their original paleomagnetic record. To investigate the mechanisms and outcomes of lightning‐induced remanent magnetization, we conducted controlled high‐current impulse experiments on ...

Magnetic properties of geraisites, the first tektite strewn field identified in Brazil

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1163-1178, July 2026.
Abstract Geraisites are a newly recognized class of tektite from Brazil. They occur as centimeter‐sized, elongated to subspherical bodies scattered across surface gravel and shallow subsurface layers within a ~90‐km‐long strewn field extending between the municipalities of São João do Paraíso and Curral de Dentro, near the border between the states of ...

Tracing Hailstone Development: Isotopic Evidence and Microphysical Variability in Texas Supercell Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Two supercell thunderstorms that occurred in Del Rio and Burkburnett, Texas in the spring of 2020 produced greater than 5 cm diameter hailstones. Fourteen hailstones, eight from Del Rio and six from Burkburnett, were cut in half along the maximum principal axis. Half the hailstone was dissected at 0.5 cm increments, providing 198 subsamples of

Beyond Point Masses. III. Detecting Haumea’s Nonspherical Gravitational Field

The Planetary Science Journal
The dwarf planet Haumea is one of the most compelling trans-Neptunian objects to study, hosting two small, dynamically interacting satellites, a family of nearby spectrally unique objects, and a ring system. Haumea itself is extremely oblate due to its 3.
