Description
Summary:The detection of pulsed radio emission from the X-ray pulsar AXP 4U 0142+61 with a period of P = 8.68832935(6) s and a period derivative of = 18.713(4) × 10 −13 s/s is reported. The observations were carried out on two high-sensitivity radio telescopes of the Pushchino Radio Astronomy Observatory: the Large Phased Array at 111MHz and the DKR-1000 at 40MHz.Mean pulse profiles are presented; the measured flux density is S 111 = 30 ± 20 mJy. The estimated distance derived from the dispersion measure, 27 pc/cm 3 , is 1.4 kpc, and the integrated radio luminosity is L R = 1.5 × 10 27 erg/cm. Comparison with X-ray data shows an appreciable difference in the pulse duration (the radio pulse is about a factor of 20 more narrow) and strong variations in the flux density.
