Observation of a Rapidly Pulsating Radio Source
TLDR
In this article, the first report of a curious class of astronomical radio sources, distinguished by their rapid and extremely regular pulsations, was made by Hewish et al. They are now understood to be rapidly rotating, magnetized neutron stars, or pulsars.Abstract:
Unusual signals from pulsating radio sources have been recorded at the Mullard Radio Astronomy Observatory The radiation seems to come from local objects within the galaxy, and may be associated with oscillations of white dwarf or neutron stars 1968 saw the first report of a curious class of astronomical radio sources, distinguished by their rapid and extremely regular pulsations Hewish et al associated them with unusually stable oscillations in compact stars They are now understood to be rapidly rotating, magnetized neutron stars, or pulsarsread more

Density dependencies of interaction strengths and their influences on nuclear matter and neutron stars in relativistic mean field theory
TL;DR: In this article, the density dependencies of various effective interaction strengths in the relativistic mean field are studied and carefully compared for nuclear matter and neutron stars, and the influences of different density dependencies are presented and discussed on mean field potentials, saturation properties, equations of state, maximum masses, and corresponding radii for neutron stars.

Neutron stars in a class of nonlinear relativistic models
TL;DR: In this paper, a class of relativistic models for nuclear matter and neutron stars which exhibits a parametrization, through mathematical constants, of the nonlinear meson-baryon couplings is introduced.

Pulsar Search at the Molonglo Radio Observatory
TL;DR: In this article, seven new pulsars are reported from the Molonglo radio observatory, and some conclusions about the distribution of pulsars in the galaxy can be drawn about the evolution of the galaxy.

Atomic calculation for the atmospheres of strongly-magnetized neutron stars
Kaya Mori,Charles J. Hailey +1 more
TL;DR: In this paper, the Hartree equation was minimized by treating exchange terms and higher Landau states by perturbation methods, which has the effect of reducing the computation time significantly.

Separation of pulsar signals from noise using supervised machine learning algorithms
TL;DR: An Artificial Neural Network Multi-Layer Perceptron (ANN MLP), Adaboost, Gradient Boosting Classifier (GBC), and XGBoost, for the separation of pulsars from radio frequency interference and other sources of noise is evaluated, using a dataset obtained from the post-processing of a pulsar search pipeline.

Interplanetary Scintillation of Small Diameter Radio Sources
TL;DR: In this article, the authors used the black-body equations to calculate the increased radiation appropriate to the observed brightness increase in the star over a 1,000 A.u. band-width at 5,400 A.U.

TL;DR: In this article, the authors discuss the association of solar cosmic rays with flare association, solar particle acceleration, recurrence and low energy solar particle events, and discuss the effects of solar particle particle acceleration.

Possible magnetospheric phenomena associated with neutron stars
TL;DR: In this paper, it was shown that the importance of the early cooling by emission of neutrinos from the Urca process has been underestimated in the foregoing investigations, and the calculations of Miss Tsuruta indicate that a neutron star will rapidly cool to 3 or 4 × 106 °K, but that after 105 years its surface temperature will still be about 2 × 106°K.
