The High-mass X-Ray Binary Luminosity Functions of Dwarf Galaxies

open access: yesThe Astrophysical Journal
Drawing from the Chandra archive and using a carefully selected set of nearby dwarf galaxies, we present a calibrated high-mass X-ray binary (HMXB) luminosity function in the low-mass galaxy regime and search for an already hinted at dependence on ...

Simultaneously Engineering the Amorphous Phase and Branch Morphology of High‐Entropy Alloy Nanomaterials for Enhanced Ethylene Glycol Oxidation

open access: yesAdvanced Materials, EarlyView.
Amorphous PdCuNiCoFe high‐entropy alloy nanobranches were developed through a versatile wet‐chemical synthetic strategy enabling simultaneous control of composition, phase, and morphology. The resulting amorphous PdCuNiCoFe nanobranches exhibit outstanding electrocatalytic performances for ethylene glycol oxidation (EGOR), delivering high selectivity ...

Stellar Wind Parameters of Massive Stars in Accretion-Powered High-Mass X-Ray Binary Pulsars

open access: yesGalaxies
The process of mass exchange between the components of High-Mass X-ray Binary (HMXB) systems with neutron stars undergoing wind-fed accretion is discussed. The X-ray luminosity of these systems allows us to evaluate the mass capture rate by the neutron star from the stellar wind of its massive companion and set limits on the relative velocity between ...

Modeling High Mass X-Ray Binaries to Double Neutron Stars through Common Envelope Evolution

open access: yesThe Astrophysical Journal
Abstract We present detailed evolutionary simulations of wide binary systems with high-mass (8–20 M ⊙) donor stars and a 1.4 M ⊙ neutron star. Mass transfer in such binaries is dynamically unstable, and common envelope (CE) evolution is followed. We use a recently developed prescription to deal with CE

Ultrathin Li Metal Anodes: Quantitative Design Principles and Manufacturability Across Liquid and Solid‐State Batteries

open access: yesAdvanced Materials, EarlyView.
Ultrathin lithium metal anodes (≤15 µm) offer a promising route to high‐energy‐density batteries due to their high capacity and low potential. This review presents design principles for ultrathin Li, evaluates fabrication strategies, and discusses challenges in liquid and solid‐state cells.
