Period changes in six contact binaries: WZ And, V803 Aql, DF Hya, PY Lyr, FZ Ori, and AH Tau

, 2008
Six contact binaries lacking a period analysis have been chosen to search for the presence of a third body. The O-C diagrams of these binaries were analyzed with the least-squares method by using all available times of minima.

A Comparative Analysis of Plasmonic and Dielectric Metasurface Sensing Platforms Powered by Bound States in the Continuum

Advanced Functional Materials, EarlyView.
This work reveals a fundamental trade‐off between plasmonic and dielectric metasurfaces for molecular sensing. A clear performance crossover is identified: dielectric metasurfaces excel in air, while plasmonic metasurfaces dominate in lossy solvents. These results establish design rules for infrared metasurface sensors and enable optimized performance ...

Emergent Magnetic Structures at the 2D Limit of the Altermagnet MnTe

Advanced Functional Materials, EarlyView.
Renewed interest in MnTe has emerged due to its intriguing altermagnetism, a newly identified form of magnetism distinct from conventional ferro‐, antiferro‐, or paramagnetism. By combining magnetic X‐ray absorption spectroscopy, scanning tunnelling microscopy, and first‐principles theory, this study reveals that thinning MnTe to the 2D limit ...
