Are radio pulsars strange stars ? [PDF]
Astronomy & Astrophysics, 2001 A remarkably precise observational relation for pulse core component widths of radio pulsars is used to derive stringent limits on pulsar radii, strongly indicating that pulsars are strange stars rather than neutron stars. This is achieved by inclusion of general relativistic effects due to the pulsar mass on the size of the emission region needed to ...

LUMINOSITIES OF RADIO PULSARS [PDF]
International Journal of Modern Physics D, 2013 Luminosity is an intrinsic property of radio pulsars related to the properties of the magnetospheric plasma and the beam geometry, and inversely proportional to the observing frequency. In traditional models, luminosity has been considered as a function of the spin parameters of pulsars.

The specifics of pulsar radio emission
Open Astronomy, 2022 A characteristic property of pulsars is pulsed periodic radio emission, which has a high stability of periods. Despite the high stability of the emission periods of pulsars, monitoring the time of arrival of pulses (timing) shows the presence of ...

Radio-quiet and radio-loud pulsars: similar in Gamma-rays but different in X-rays [PDF]
, 2015 We present new Chandra and XMM-Newton observations of a sample of eight radio-quiet Gamma-ray pulsars detected by the Fermi Large Area Telescope. For all eight pulsars we identify the X-ray counterpart, based on the X-ray source localization and the best

Radio pulsars in Terzan 5 [PDF]
Monthly Notices of the Royal Astronomical Society, 2000 We report on searches of the globular cluster Terzan 5 for low luminosity and accelerated radio pulsars using the 64-m Parkes radio telescope. One new millisecond pulsar, designated PSR J1748-2446C, was discovered, having a period of 8.44ms. Timing measurements using the 76-m Lovell radio telescope at Jodrell Bank show that it is a solitary pulsar and ...

Radio Quiet Pulsars with Ultra-Strong Magnetic Fields [PDF]
, 1998 The notable absence of radio pulsars having measured magnetic dipole surface field strengths above $B_0\sim 3\times 10^{13}$ Gauss naturally raises the question of whether this forms an upper limit to pulsar magnetization.

High magnetic field pulsars and magnetars: a unified picture [PDF]
, 2000 We propose a unified picture of high magnetic field radio pulsars and magnetars by arguing that they are all rotating high-field neutron stars, but have different orientations of their magnetic axes with respective to their rotation axes.

A Survey of 56 Mid-latitude EGRET Error Boxes for Radio Pulsars [PDF]
, 2006 We have conducted a radio pulsar survey of 56 unidentified gamma-ray sources from the 3rd EGRET catalog which are at intermediate Galactic latitudes (5 deg. < |b| < 73 deg.).

Wide radio beams from gamma-ray pulsars
, 2010 We investigate the radio and gamma-ray beaming properties of normal and millisecond pulsars by selecting two samples from the known populations. The first, Sample G, contains pulsars which are detectable in blind searches of gamma-ray data from the Fermi
