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

The Transits of Extrasolar Planets with Moons
TL;DR: In this article, the authors proposed a method to detect exomoons through their gravitational influence on the host planet, giving rise to transit timing and duration variations (TTV and TDV).

A new statistical method for the structure of the inner crust of neutron stars
TL;DR: In this article, the structure of the low density regions of the inner crust of neutron stars using the Hartree-Fock-Bogoliubov (HFB) model was investigated.
Journal ArticleDOI
Radio Pulsars
TL;DR: In this paper, the authors report on three aspects of pulsar structure that have seen recent progress: the self-consistent theory of the magnetosphere of an oblique magnetic rotator, location, geometry, and optics of radio emission; and evolution of the angle between spin and magnetic axes.
Journal ArticleDOI
Intensity Variations of the Pulsar CP 1919
TL;DR: Inference about the origin of the variations can be drawn from measurements of intensity distributions, power spectra and cross correlations between several frequencies as mentioned in this paper, which can be used to identify the source of variations.

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.

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.
