X-ray Emission from Psr 0355+54
We have obtained a 20 ks observation of PSR 0355+54 using the ROSAT PSPC. The pulsar is detected with a count rate of 4:2(1:3) 10 ?3 s ?1 above the background. While the 70 source counts are insuucient for spectral tting, we have derived source parameters for speciic cases of power law as well as blackbody spectra. For a Crab-like spectrum (photon index = 2) we nd L x (0:1 ? 2:4 keV) = 1:0 10 3...
متن کاملThe Pulsed Soft X–ray Emission from Psr 0656+14
We present the results of a spectral and timing analysis of PSR 0656+14 based on the complete set of ROSAT observations carried out with the PSPC instrument in 1991 and 1992. The present analysis confirms the thermal origin of the bulk of the emission in the soft X-ray band (Finley et al. 1992). In addition, we find strong evidence of a harder component, described equally well with a blackbody ...
متن کاملDetection of Pulsed X-ray Emission from Psr B1706−44
We report the first detection of pulsed X-ray emission from the young, energetic radio and gammaray pulsar PSR B1706−44. In a 47 ks observation with the High Resolution Camera on-board the Chandra X-ray Observatory we find a pulsed signal at a frequency consistent with the radio ephemeris, f = 9.7588081± 0.0000027 Hz (at epoch 51585.34104 MJD). The broad, single-peaked pulse profile has a pulse...
متن کاملX - ray Emission Properties of the Old Pulsar PSR B 2224 + 65
Using archival Chandra data we studied the X-ray emission properties of PSR B2224+65 and its environment. Albeit limited by photon statistics the spectral analysis suggests that the bulk of the emission from PSR B2224+65 is non-thermal. Fitting a power-law to the observed energy spectrum yields a photon index of Γ = 1.58 +0.43 −0.33. The possible origin of the non-thermal pulsar emission is dis...
