Sensitivity of the Neutron Star Equation of State Inferences to Mass and Radius Measurements

Dmitry D. Ofengeim, Peter S. Shternin, Tsvi Piran

We examine how inferences of the neutron-star equation of state depend on mass and radius observations. We update previous results with recent measurements combined with theoretica…

Neutrino pair bremsstrahlung due to electromagnetic collisions in neutron star cores revisited

P. S. Shternin

We reconsider the problem of neutrino pair bremsstrahlung emission originating from the electromagnetic collisions of charged particles in nucleonic () neutron star cores. Tw…

Verification of Cas A neutron star cooling rate using Chandra HRC-S observations

Jiaqi Zhao, Craig O. Heinke, Peter S. Shternin +3

The young neutron star (NS) in the Cassiopeia A (Cas A) supernova remnant is a fascinating test for theories of NS cooling. Chandra observations have indicated that its surface tem…

A three-parameter characterization of neutron stars' mass-radius relation and equation of state

Dmitry D. Ofengeim, Peter S. Shternin, Tsvi Piran

Numerous models of neutron star (NS) equation of state (EoS) exist based on different superdense-matter physics approaches. Nevertheless, some NS properties show universal (EoS-ind…

Constraints on neutron star superfluidity from the cooling neutron star in Cassiopeia A using all Chandra ACIS-S observations

Peter S. Shternin, Dmitry D. Ofengeim, Craig O. Heinke +1

Analysis of Chandra observations of the neutron star (NS) in the centre of the Cassiopeia A supernova remnant taken in the subarray (FAINT) mode of the ACIS detector performed by P…

Transport coefficients of magnetized neutron star cores

Peter Shternin, Dmitry Ofengeim

We review the calculations of the kinetic coefficients (thermal conductivity, shear viscosity, momentum transfer rates) of the neutron star core matter within the framework of the…
