Radio-quiet neutron star 1E 1207.4-5209: a possible strong Gravitational-wave source
B. P. Gong
There are four puzzles on 1E 1207.4-5209: (1) the characteristic age of the pulsar is much higher than the estimated age of the supernova remnant; (2) the magnetic field inferred f…
On the nature of the radio quiet X-ray neutron star 1E 1207.4-5209
Biping Gong, G. F. Bignami
The strange timing property of X-ray pulsar 1E 1207.4-5209 can be explained by the hypothesis that it is a member of an ultra-compact binary system. This paper confronts the ultra-…
The precession of orbital plane and the significant variabilities of binary pulsars
Biping Gong
There are two kinds of expressions on the precession of orbital plane of a binary pulsar system, which are given by Barker $&$ O'Connell (1975) and Apostolatos et al. (1994), Kidde…
Secular variability, geodetic precession and moment of inertia of binary pulsars
B. P. Gong
More and more binary pulsars show significant secular variations, in which the measured projected semi-major axis, , and the first derivative of orbital period, $\do…
