Truly eccentric - I. Revisiting eight single-eccentric planetary systems

, 2019
We examine eight known single-eccentric planetary systems in light of recently released large data archives and new analysis techniques. For four of these systems (HD 7449, HD 65216, HD 89744, HD 92788) we find evidence for additional long-period ...

Inferring stellar metallicity and elemental abundances from kinematic and spectroscopic data using machine learning

Astronomy & Astrophysics
Context. Elemental abundances of FGK stars can be derived routinely from high-resolution optical spectra, but this remains considerably more difficult for cooler stars.

Wood‐Derived Nanocellulose‐Biocarbon Fresnel‐Zone Plate Lenses for Sub‐THz Frequency Applications

Advanced Materials Technologies, EarlyView.
Wood‐derived nanocellulose and lignin‐based biocarbon were combined to fabricate fully bio‐based Fresnel zone plate (FZP) lenses for sub‐terahertz frequencies. These sustainable FZP lenses exhibit low dielectric loss and high directivity, achieving performance comparable to that of metallic references, and remain functional under environmental stress ...

Ariel stellar characterisation

Astronomy & Astrophysics
Context. The characterisation of exoplanetary systems depends on the accurate determination of host star parameters. The Ariel mission will probe the atmospheres of a statistically significant sample of exoplanets, and so requires a precise ...

3D‐Printed Dual‐Doped Ag2Se‐Based Thermoelectric Films With Enhanced Thermal Stability

Advanced Materials Technologies, EarlyView.
Sb–Se dual doping enhances the thermal stability of Ag2Se‐based thermoelectric systems. The compositionally tuned nano‐ink is printed into flexible films by direct ink writing (DIW), retaining improved thermoelectric properties after annealing up to 400°C.

Multilayer Biobased Poly(ethylene furanoate)/Graphene Oxide Nanofibrous Membranes With Directional Water Transport for Efficient Microplastics Filtration

Advanced Materials Technologies, EarlyView.
A self‐assembled multilayer biobased PEF/GO nanofibrous membrane was developed by electrospinning for efficient PLA microplastics (MPs) filtration. The membrane combines superhydrophilicity, directional water transport, mechanical robustness, and a synergistic size‐exclusion interception and electrostatic repulsion MPs separation mechanism, enabling ...
