Abstract

Using the observation data of Parkes 64 m radio telescope at a central frequency of 1369 MHz, the pulse nulling phenomenon of PSR J1701–3726 was analyzed. It is found that the pulse nulling phenomenon of this pulsar has quasi-periodic, and the quasi-period value approximately is 81.25P, where P is the rotation period, and the pulse nulling ratio NF (Nulling Fraction) is calculated to be 27%±0.97%. Further study on the change of relative energy in the on-pulse region over time shows that there are four different switching modes a, b, c, and d between null state and burst state, among which mode a occurs 23 times, mode b occurs 6 times, mode c occurs 5 times, and mode d occurs 79 times, indicating that there may be some randomness in state transitions.

期刊介绍: The vigorous growth of astronomical and astrophysical science in China led to an increase in papers on astrophysics which Acta Astronomica Sinica could no longer absorb. Translations of papers from two new journals the Chinese Journal of Space Science and Acta Astrophysica Sinica are added to the translation of Acta Astronomica Sinica to form the new journal Chinese Astronomy and Astrophysics. Chinese Astronomy and Astrophysics brings English translations of notable articles to astronomers and astrophysicists outside China.
