A Relativistic Double Neutron Star Binary PSR J1846-0513

Publikováno v: The Astrophysical Journal Letters, Vol 964, Iss 1, p L7 (2024)

We report the timing analysis of PSR J1846−0513, a pulsar discovered by the Five-hundred-meter Aperture Spherical radio Telescope (FAST) in Commensal Radio Astronomy FAST Survey. The pulsar possesses a spin period of 23.36 ms and a spin-down rate (

Publikováno v: The Astrophysical Journal, Vol 965, Iss 1, p 25 (2024)

How pulsars radiate is a long-standing problem. Detailed polarization measurements of individual pulses shed light on currently unknown emission processes. Recently, based on supersensitive observations, dwarf pulses have been recognized as weak narr

PSR J2150+3427 is a 0.654 s pulsar discovered by the Commensal Radio Astronomy FAST Survey. From the follow-up observations, we find that the pulsar is in a highly eccentric orbit ( e = 0.601) with an orbital period of 10.592 days and a projected sem

Results of 12 Years of Pulsar Timing at Nanshan -- I

Autor: J. P. Yuan, Na Wang, R. N. Manchester, F. F. Kou, J. B. Wang, S. J. Dang, Z. Y. Liu, George Hobbs, L.-J. Li

We have used the Nanshan 25-m Radio Telescope at Xinjiang Astronomical Observatory to obtain timing observations of 87 pulsars from 2002 July to 2014 March. Using the "Cholesky" timing analysis method we have determined positions and proper motions f

Publikováno v: Science China Physics, Mechanics & Astronomy. 62

Rotating radio transients (RRATs) are peculiar astronomical objects whose emission mechanism remains under investigation. In this paper, we present observations of three RRATs, J1538+2345, J1854+0306 and J1913+1330, observed with the Five-hundred-met
