| 1 | Subpulse Drifting of PSR J1110–5637显示文摘We report a detailed study of polarization characteristics and subpulse drifting in PSR J1110-5637 with the observations of the Parkes 64 m radio telescope at 1369 MHz.The observations revealed that the trailing component of the pulse profile has obvious subpulse drifting,while the leading component has no subpulse drifting.Using the two-dimensional fluctuation spectrum(2DFS),we detected three distinct emission modes in the trailing component(modes A,B and C).The emission in mode A is chaotic and indistinguishable,while modes B and C have obvious subpulse drifting.The vertical modulation periods P3of modes B and C are around the mean values of 12 P and 8 P,respectively.The subpulse drifting of PSR J1110-5637 will expand the pulsar sample with multiple subpulse drifting rates,and this will help future systematic studies on the physical origin of the subpulse drifting phenomenon. | S.J.Dang L.H.Shang L.Lin Q.J.Zhi R.S.Zhao C.B.Wu Z.Y.You A.J.Dong J.T.Bai X.Xu D.D.Zhang H.Yang Q.W.Lin | 2022 | Research in Astronomy and Astrophysics2022，22，6： | 0 |
