New age‐estimate data and implications for marine isotope stage 7 and 5e sea levels in Fenland, eastern England

Journal of Quaternary Science, EarlyView.
ABSTRACT Only one last interglacial relative sea‐level indicator point (SLIP) has been recognised for Fenland, eastern England, and the nearest penultimate interglacial SLIP is located on the north Norfolk coast. Such limited information restricts the regional input to, and hence the relevance of, global reconstructions of late Middle and Late ...

Mapping the Galactic Disk with the LAMOST and Gaia Red Clump Sample. VIII. Mapping the Kinematics of the Galactic Disk Using Mono-age and Mono-abundance Stellar Populations

The Astrophysical Journal
We present a comprehensive study of the kinematic properties of the different Galactic disk populations, as defined by the chemical abundance ratios and stellar ages, across a large disk volume (4.5 ≤ R ≤ 15.0 kpc and ∣ Z ∣ ≤ 3.0 kpc), by using the ...

Highly Durable and Uniform Structural Coloration via Spray‐Coated Organic Mie Resonators Randomly Distributed in Three Dimensions

Laser &Photonics Reviews, EarlyView.
This study demonstrates uniform, durable non‐iridescent structural coloration using polystyrene nanoparticles randomly embedded in a thick sodium silicate with absorptive additives. By suppressing the effects of the structure factor and multiple scattering, this approach achieves uniform coloration from the backscattering.

Accurate, Precise, and Physically Self-consistent Ages and Metallicities for 400,000 Solar Neighborhood Subgiant Branch Stars

The Astrophysical Journal
Age is the most difficult fundamental stellar parameter to infer for isolated stars. While isochrone-based ages are in general imprecise for both main-sequence dwarfs and red giants, precise isochrone-based ages can be obtained for stars on the subgiant ...

Metallicity and α-abundance for 48 Million Stars in Low-extinction Regions in the Milky Way

The Astrophysical Journal
We estimate ([M/H], [ α /M]) for 48 million giants and dwarfs in low-dust extinction regions from the Gaia DR3 XP spectra by using tree-based machine learning models trained on APOGEE DR17 and a metal-poor star sample from Li et al.

Aster tongrenensis (Asteraceae), a remarkable new species from Guizhou, China

Nordic Journal of Botany, EarlyView.
Aster tongrenensis (Asteraceae), a remarkable new species from Guizhou, China, is here described, illustrated and compared with related taxa based on integrated evidence from morphology, micromorphology and molecular phylogeny. Morphological and micromorphological observations indicate that A. tongrenensis is most similar to A.
