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 article, the results from the low-frequency (40-78 MHz) extension of the first pulsar census of non-recycled pulsars carried out with the LOw-Frequency ARray (LOFAR) were presented.

Radio observations of five pulsars.
Andrew Lyne,B. J. Rickett +1 more
TL;DR: In this paper, the authors describe measurements of the positions, periods, dispersions and pulse shapes obtained at frequencies of 151 MHz, 408 MHz, and 610 MHz using a 250 foot telescope at Jodrell Bank.

Timing Gamma-ray Pulsars with the Fermi Large Area Telescope: Timing Noise and Astrometry
TL;DR: In this article, the authors constructed timing solutions for 81 gamma-ray pulsars covering more than five years of Fermi data, including radio-quiet or radio-faint pulsars which cannot be timed with other telescopes.

Can cold quark matter be solid
TL;DR: The state of cold quark matter challenges both astrophysicists and particle physicists, and even many-body physicists as mentioned in this paper, and it is conventionally suggested that BCS-like color superconductivity occurs in cold Quark matter; however, other scenarios with a ground state rather than of Fermi gas could still be possible.

Fifteen Months of Pulsar Astronomy
TL;DR: In this article, a series of pulses from CP 1919, the first pulsar, is shown in Figure 1, and one notices both the regularity of the pulses and the variation in their amplitude with time.

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.
