Wide binary stars in the Galactic field : a statistical approach [PDF]

open access: yes, 2010
This thesis focuses on the statistical properties of wide binary (WB) star systems in the Galactic field. With projected separations larger than 200 AU and, consequently, having very low binding energies, WB are sensitive probes of the Galactic ...

GeS as an Emerging OTS Material: Atomic Structure and Modeling of ON/OFF Switching

open access: yesAdvanced Functional Materials, EarlyView.
The structural puzzle of glassy GeS, an advanced memory‐selector material, has finally been disentangled, revealing a patchwork of mixed tetrahedral and trigonal species. Under a high electric field, over‐ and under‐coordinated Ge and S defects, together with three‐membered rings, form an interconnected network associated with localized and extended ...

Flux Variations and Torque Reversals of Cen X-3

open access: yesThe Astrophysical Journal
Cen X-3 is an archetypical X-ray pulsar with strong flux variations and alternating torque reversals, both of which are similar to those of recently discovered pulsating ultraluminous X-ray sources.

Neuromorphic Devices for Extreme Environments: State‐Variable Reliability and Stabilization Strategies

open access: yesAdvanced Functional Materials, EarlyView.
Neuromorphic devices for extreme environments are interpreted through the physical states that store and process information. Radiation, temperature extremes, and vacuum can perturb vacancies, filaments, trapped charges, polarization, interfaces, and readout signals.

Evidence for a Cyclotron Absorption Line and Spectral Transition in EXO 2030+375 during the 2021 Giant Outburst

open access: yesThe Astrophysical Journal
Based on Insight-HXMT observations of EXO 2030+375 during its 2021 giant outburst, we report the analysis of pulse variations and the broadband X-ray spectrum, and find the presence of a potential cyclotron resonant scattering feature (CRSF) with the ...

High-mass X-ray binaries and OB runaway stars

open access: yes, 2004
High-mass X-ray binaries (HMXBs) represent an important phase in the evolution of massive binary systems and provide fundamental information on the properties of the OB-star primaries and their compact secondaries (neutron star, black hole).

A Particle‐Level Dual‐Polymer Interphase for Coupled Interfacial and Contact Stabilization of Zinc Metal Powder Anodes in Aqueous Zinc‐Ion Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A particle‐level dual‐polymer interphase of carboxymethyl cellulose (CMC) and poly(acrylic acid) (PAA) stabilizes zinc metal powder anodes by coupling CMC‐mediated water regulation with PAA‐derived Zn2+ affinity. This synergy suppresses hydrogen evolution, corrosion, and byproduct accumulation while preserving electrode‐level electrical contact ...

Finding periods in the high mass x-ray binary stars of the magellanic clouds [PDF]

open access: yes, 2010
High Mass X-Ray Binary Stars (HMXBs) are stars that contain one early-type main sequence or giant star and one of a black hole, neutron star or white dwarf. HMXBs in the Large Magellanic Cloud (LMC) and the Small Magellanic Cloud (SMC) are instructive to

X-rays from quiescent low-mass X-ray binary transients

open access: yes, 2000
International audienceI argue that it is very unlikely that X- rays from quiescent black-hole low-mass X-ray binary transients are emitted by coronae of companion stars.
