Constraints on axion-like particles and nucleon pairing in dense matter from the hot neutron star in HESS J1731-347 [PDF]

Physical Review C, 2018
If the thermal evolution of the hot young neutron star in the supernova remnant HESS J1731-347 is driven by neutrino emission, it provides a stringent constraint on the coupling of light (mass $\ll 10$ keV) axion-like particles to neutrons.

The entrainment matrix of a superfluid neutron-proton mixture at a finite temperature [PDF]

, 2005
The entrainment matrix (also termed the Andreev-Bashkin matrix or the mass-density matrix) for a neutron-proton mixture is derived at a finite temperature in a neutron star core. The calculation is performed in the frame of the Landau Fermi-liquid theory

Temperature-dependent pulsations of superfluid neutron stars [PDF]

Monthly Notices of the Royal Astronomical Society, 2006
We examine radial oscillations of superfluid neutron stars at finite internal temperatures. For this purpose we generalize the description of relativistic superfluid hydrodynamics to the case of superfluid mixtures. We show that in a neutron star at hydrostatic and beta-equilibrium the red-shifted temperature gradient is smoothed out by neutron ...

Cooling of the Cassiopeia A neutron star and the effect of diffusive nuclear burning

, 2019
The study of how neutron stars cool over time can provide invaluable insights into fundamental physics such as the nuclear equation of state and superconductivity and superfluidity.

Rapidly solidified highly alloyed Ni-based superalloy powders for multi-application: The faster the cooling, the softer?

Materials & Design
An investigation was conducted on gas atomised (GA) highly alloyed Ni-based superalloy powders utilised in diverse processes including additive manufacturing (AM), wide gap brazing (WGB) and hot isostatic pressing (HIP).

Incommensurate Crystallization of Neutron Matter in Neutron Stars

East European Journal of Physics, 2020
The composition of the neutron stars from its surface region, outer-core, inner-core, and to its center is still being investigated. One can only surmise on the properties of neutron stars from the spectroscopic data that may be available from time to ...

Time-Resolved Neutron Bragg-Edge Imaging: A Case Study by Observing Martensitic Phase Formation in Low Temperature Transformation (LTT) Steel during GTAW

Applied Sciences, 2021
Polychromatic and wavelength-selective neutron transmission radiography were applied during bead-on-plate welding on 5 mm thick sheets on the face side of martensitic low transformation temperature (LTT) steel plates using gas tungsten arc welding (GTAW).

Temperature dependence of elastic and plastic deformation behavior of a refractory high-entropy alloy

Science Advances, 2020
The present work discovers the unique deformation behavior of a refractory high-entropy alloy at elevated temperatures. Single-phase solid-solution refractory high-entropy alloys (HEAs) show remarkable mechanical properties, such as their high yield ...
