| 摘要 | We present the phase-connected timing solutions of all five pulsars in globular cluster M3 (NGC 5272), namely PSRs M3A to F (PSRs J1342+2822A to F), with the exception of PSR M3C, from FAST archival data. In these timing solutions, those of PSRs M3E and F are obtained for the first time. We find that PSRs M3E and F have low-mass companions and are in circular orbits with periods of 7.1 and 3.0 days, respectively. For PSR M3C, we have not detected its signal in all 41 observations. We found no X-ray counterparts for these pulsars in archival Chandra images in the band of 0.2-20 keV. From the autocorrelation function analysis of M3A and M3B's dynamic spectra, the scintillation timescale ranges from 7.0 +/- 0.3 to 60.0 +/- 0.6 minutes, and the scintillation bandwidth ranges from 4.6 +/- 0.2 to 57.1 +/- 1.1 MHz. The measured scintillation bandwidths from the dynamic spectra indicate strong scintillation, and the scattering medium is anisotropic. From the secondary spectra, we captured a scintillation arc only for PSR M3B with a curvature of 649 +/- 23 m-1 mHz-2. |
