Radio Polarization of the Young High - Magnetic - Field Pulsar Psr

We have investigated the radio polarization properties of PSR J1119−6127, a recently discovered young radio pulsar with a large magnetic field. Using pulsar-gated radio imaging data taken at a center frequency of 2496 MHz with the Australia Telescope Compact Array, we have determined a rotation measure for the pulsar of +842± 23 rad m. These data, combined with archival polarimetry data taken a...

Optical spectroscopy of the radio pulsar PSR B 0656 + 14

We have obtained the spectrum of a middleaged PSR B0656+14 in the 4300-9000Å range with the ESO/VLT/FORS2. Preliminary results show that at 4600-7000Å the spectrum is almost featureless and flat with a spectral index αν≃-0.2 that undergoes a change to a positive value at longer wavelengths. Combining with available multiwavelength data suggests two wide, red and blue, flux depressions whose fre...

Psr J0045{7319: a Dual-line Binary Radio Pulsar

Binary radio pulsars are superb tools for mapping binary orbits, because of the precision of the pulse timing method (e.g Taylor & Weisberg 1989). To date, all orbital parameters for binary pulsars have been derived from observations of the pulsar alone. We present the rst observations of the radial velocity variations due to the binary motion of a companion to a radio pulsar. Our results demon...

Psr J1847−0130: a Radio Pulsar with Magnetar Spin Characteristics

We report the discovery of PSR J1847−0130, a radio pulsar with a 6.7-s spin period, in the Parkes multibeam survey of the Galactic plane. The slowdown rate for the pulsar, 1.3 × 10 s s, is high and implies a surface dipole magnetic field strength of 9.4 × 10 G. This inferred dipolar magnetic field strength is the highest by far among all known radio pulsars and over twice the “quantum critical ...

Rosat Observations of the Radio and Gamma-ray Pulsar Psr 1706-44 Rosat Observations of the Radio and Gamma-ray Pulsar Psr 1706-44

We report on the detection of PSR 1706-44 in two ROSAT-PSPC observations. The recorded source counts are unpulsed with a 2 pulsed fraction upper limit of 18%. Spectral analysis did not distinguish between black-body and power law models; however, we argue that the lack of pulsations and the similarity in the pulsar's spin parameters to those of the Vela pulsar favour a power law model dN=dE / E...
