Spectra disentangling applied to the Hyades binary Theta^2 Tau AB: new orbit, orbital parallax and component properties

, 2010
Theta^2 Tauri is a detached and single-lined interferometric-spectroscopic binary as well as the most massive binary system of the Hyades cluster. The system revolves in an eccentric orbit with a periodicity of 140.7 days.

Electrically Binary and Ternary Convertible CMOS Inverter and Logic Gate Using Complementary Field‐Effect Transistors Based on Vertically Stacked MoS2/WSe2 n‐/p‐ Field‐Effect Transistors

Advanced Functional Materials, EarlyView.
In this work, a reconfigurable T‐CMOS inverter based on vertically stacked MoS2 and WSe2 MOSFETs with a gate‐tunable MoS2 resistor, enabling stable ternary logic, is demonstrated. The T‐CMOS inverter supports electrical switching between ternary and binary modes and is further extended to implement ternary NAND (NMIN) and NOR (NMAX) logic gates ...

Three-dimensional Orbit and Dynamical Masses of GJ 105 AC

The Astrophysical Journal
The precision of stellar models is higher than the precision at which we are able to measure the masses of most stars, with the notable exception of binaries where we can determine dynamical masses of the component stars.

High‐Density Boron Nitride Nanotube Composites via Surfactant‐Stabilized Lyotropic Liquid Crystals for Enhanced Space Radiation Shielding

Advanced Functional Materials, EarlyView.
High‐density BNNT films, enabling mechanical robustness and high space radiation shielding effectiveness, are fabricated using surfactant‐stabilized BNNT liquid crystal. Simulations indicate that a 50 g cm−2 BNNT film can reduce radiation exposure by 56% compared to zero shielding, potentially doubling the duration of astronaut missions on the lunar ...

Eclipsing Binary Stars: the Royal Road to Stellar Astrophysics [PDF]

, 2012
Russell (1948) famously described eclipses as the "royal road" to stellar astrophysics. From photometric and spectroscopic observations it is possible to measure the masses and radii (to 1% or better!), and thus surface gravities and mean densities, of ...

Modelling Thermal Halide Exchange of Perovskite Powders With and Without BMIMBF4 From an Interdiffusion Perspective

Advanced Functional Materials, EarlyView.
Halide diffusion limits the stability of hybrid halide perovskites for optoelectronic applications and thus needs to be quantified. This study presents an effective interdiffusion model to obtain time‐dependent diffusion coefficients for I− and Br− diffusion from in situ X‐ray diffraction data during the formation of a solid solution MAPbIxBr3‐x from ...

Higher‐Order Temporal Dynamics in Complementary Charge Trap Memristor for High‐Dimensional Reservoir Computing

Advanced Functional Materials, EarlyView.
A complementary charge‐trap memristor (CoCTM) featuring a unique current transient with tunable overshoot‐relaxation dynamics is introduced for high‐resolution reservoir computing. By leveraging higher‐order temporal dynamics from engineered trapping layers, the device generates multiple output states from a single input, forming rich, high‐dimensional
