Matter at high density and low temperature is expected to be a color superconductor, which
is a degenerate Fermi gas of quarks with a condensate of Cooper pairs near the Fermi …

Magnetars are a special type of neutron stars, considered to have extreme dipole magnetic
fields reaching∼ 1 0 11 T. The magnetar 4U 0142+ 61, one of the prototypes of this class …

The Suzaku data for the highly variable magnetar 1E 1547.0− 5408, obtained during the
2009 January activity, were reanalyzed. The 2.07 s pulsation, detected in the 15–40 keV …

We present an analysis of the timing observations on 27 radio pulsars, collected at
Hartebeesthoek Radio Astronomy Observatory (HartRAO), with time spans ranging …

A quantitative analysis of radio pulsar timing noise is presented. Our analysis employs the
recently reported strong correlation (with correlation coefficient r= 0.95) between the …

In order to study precession and interstellar magnetic field variations, we measured the
polarized position angle of 81 pulsars at several-month intervals for four years. We show that …

Quasi-regular timing observations obtained, using the 26 m Hartebeesthoek Radio
Astronomy Observatory radiotelescope near center frequencies of 1.668 and 2.272 GHz …

We present a study of the shear modulus of the crystalline color superconducting phase of
quark matter, showing that this phase of dense, but not asymptotically dense, quark matter …

Aims. We propose a model for rotating current patterns within radiopulsar polar cap
accelerators which has observational consequences that mimic those which have been …
