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

TL;DR: In this paper, a set of equations which govern the nonlinear dynamics of drift-Alfven waves in an inhomogeneous relativistic electron-positron plasma with a small admixture of heavy ions is derived.

Strongly magnetized pulsars: explosive events and evolution
TL;DR: In this article, the role of magnetic fields in the evolution of neutron stars is discussed, and a unified unification scheme for different observational manifestations in which they appear is presented. But the most magnetised neutron stars exhibit an amazing assortment of explosive events, underlining the importance of their magnetic field in their lives.

TL;DR: In this paper , the Fermi-LAT Collaboration implemented a pulsar timing array using gamma rays and achieved a sensitivity close to that of the radio approaches, which set an independent upper limit on the gravitational wave background, which is subject to different noise sources.

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.
