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

Detection of 25 new rotating radio transients at 111 MHz
TL;DR: In this paper, the authors present 34 transients detected at meter wavelengths in their daily monitoring at declinations −9° ≤ δ ≤ +42°, and confirm the detection of 7 RRATs based on early observations.
Recursive Estimation of Spacecraft Position Using X-ray Pulsar Time of Arrival Measurements
TL;DR: In this paper, a description of blending pulsar-derived range measurements within a Kalman filter for Earth-orbiting spacecraft navigation is presented, and several examples at different orbital altitudes are presented to determine the expected navigation performance using recursive measurements obtained from models of pulsed X-ray signals.

Wind accretion: Theory and observations
TL;DR: In this paper, a review of wind accretion in high-mass X-ray binaries is presented, focusing on different regimes of quasi-spherical accretion onto the neutron star (NS): the supersonic (Bondi) accretion, which takes place when the captured matter cools down rapidly and falls supersonically towards the NS magnetosphere, and subsonic (settling), which occurs when plasma remains hot until it meets the magnetospheric boundary.

The physics of dense hadronic matter and compact stars
TL;DR: In this article, the properties of hadronic phases of dense matter in compact stars are described and the effects of symmetry energy, onset of hyperons and meson condensation on stellar configurations are demonstrated on specific examples.

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.
