ROSAT HRI Observations of the Crab Pulsar: An Improved Temperature upper limit for PSR 0531+21 [PDF]

, 1995
ROSAT HRI observations have been used to determine an upper limit of the Crab pulsar surface temperature from the off-pulse count rate. For a neutron star mass of 1.4 \Mo and a radius of 10 km as well as the standard distance and interstellar column ...

Stacking Fault Energy Analyses of Additively Manufactured Stainless Steel 316L and CrCoNi Medium Entropy Alloy Using In Situ Neutron Diffraction

Scientific Reports, 2020
Stacking fault energies (SFE) were determined in additively manufactured (AM) stainless steel (SS 316 L) and equiatomic CrCoNi medium-entropy alloys. AM specimens were fabricated via directed energy deposition and tensile loaded at room temperature.

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 ...

Nuclear Superfluidity and Specific Heat in the Inner Crust of Neutron Stars

, 2004
We analyse the temperature dependence of pairing correlations in the inner crust matter of neutron stars. The study is done in a finite-temperature HFB approach and by using a zero range pairing force adjusted to the pairing properties of infinite ...

The neutron moderation theory, taking into account a moderating medium temperature

Trudy Odesskogo Politehničeskogo Universiteta, 2017
In this paper, in the framework of the gas model, based on the solution of the kinematic problem of the neutron elastic scattering on the nucleus in the “L” system in the general case, that is, when prior to the scattering not only the neutron, but also ...
