Detection of Simultaneous Quasiperiodic Oscillation Triplets in 4U 1728-34 and Constraining the Neutron Star Mass and Moment of Inertia

open access: yesThe Astrophysical Journal
We report simultaneous detection of twin kHz and ∼40 Hz quasiperiodic oscillations (QPOs) in the time-resolved analysis of the AstroSat/LAXPC observation of the neutron star low-mass X-ray binary, 4U 1728-34.

Disordered Rocksalts as High‐Energy and Earth‐Abundant Li‐Ion Cathodes

open access: yesAdvanced Materials, EarlyView.
Disordered rocksalts with lithium excess (DRX) offer a new direction in Li‐ion cathode design beyond conventional Ni‐ and Co‐based materials. This review highlights the design principles, synthesis strategies, and performance optimization of DRX oxides and oxyfluorides for energy‐dense, sustainable batteries using Earth‐abundant transition metals and ...

Electrobaryonic axion: hair of neutron stars

open access: yesJournal of High Energy Physics
Axion-like particles are predicted in many physics scenarios beyond the Standard Model (SM). Their interactions with SM particles may arise from the triangle anomaly of the associated global symmetry, along with other SM global and gauge symmetries ...

Stiffening Liquid Crystal Elastomers with Liquid Crystal Inclusions

open access: yesAdvanced Materials, EarlyView.
Incorporation of low molecular weight liquid crystals (LC) into liquid crystal elastomers (LCE) leads to a significant increase in their stiffness and output work density. Such remarkable stiffening is attributed to nanoscale phase‐separation and the formation of induced‐smectic domains in polydomain and monodomain LC‐LCEs, respectively.

On the Dynamical Evolution of the Asteroid Belt in a Massive Star–Neutron Star Binary

open access: yesThe Astrophysical Journal
Some fast radio bursts (FRBs) exhibit repetitive behaviors, and their origins remain enigmatic. It has been argued that repeating FRBs could be produced by the interaction between a neutron star and an asteroid belt.

AI‐Driven Defect Engineering for Advanced Thermoelectric Materials

open access: yesAdvanced Materials, EarlyView.
This review presents how AI accelerates the design of defect‐tuned thermoelectric materials. By integrating machine learning with high‐throughput data and physics‐informed representations, it enables efficient prediction of thermoelectric performance from complex defect landscapes.

Accretion in supergiant High Mass X-ray Binaries

open access: yesEPJ Web of Conferences, 2014
Supergiant High Mass X-ray Binary systems (sgHMXBs) consist of a massive, late type, star and a neutron star. The massive stars exhibits strong, radiatively driven, stellar winds.
