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

Dottorato di ricerca in fisica
TL;DR: In this paper, different strategies are proposed to modulate the intrinsic properties of sub-nm graphene nanostructures, and the results provide insights into the fundamental properties of GNNs and show promising perspectives in view of graphene-based optoelectronics and spintronics.

X-ray spectral and timing properties of the high Mass X-ray binaries GX 304-1 and Vela X-1
TL;DR: In this article, the spectroscopical and timing analysis of two accreting X-ray pulsars, namely the Be/X-ray Binary GX 304-1 and the wind-fed binary Vela X-1, is presented.

Very high energy gamma rays from the binary pulsar PSR B1259-63
TL;DR: In this article, a very high energy (VHE) γ-ray emission of the binary system PSR B1259−63 /SS 2883 was detected with a total significance above 13σ.

Pulsars: gigantic nuclei
TL;DR: In this paper, it is argued that a pulsar is very similar to an extremely big nucleus, but is a little bit different from the gigantic nucleus speculated 80 years ago by L. Landau.

Radio and X-ray burst from PSR 0950+08
TL;DR: In this paper, a burst from PSR 0950+08 was observed by two radio telescopes (separated by ~ 200 km) operating at 103 MHz, and the X-ray flux during the event compares with that during a solar Xray flare.

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.
