A Statistical Study on the Low-Frequency QPO Amplitude Spectrum and Amplitude in GRS 1915+105
Shu-Ping Yan, Guo-Qiang Ding, Na Wang +2
A statistical study was made on both the energy dependence of the low-frequency quasi-periodic oscillation (QPO) amplitude (LFQPO amplitude spectrum) and the LFQPO amplitude from a…
The evolution of inner disk radius with orbital phase in Circinus X-1
Yanan Wang, Guoqiang Ding, Chunping Huang
Using RXTE observations, we investigate the evolution of inner disk radius R_in of Cir X-1 during two cycles and find obvious orbital modulation. We argue that the modulation is at…
Phase-Resolved Timing Analysis of GRS 1915+105 in Its ρ State
Shu-Ping Yan, Na Wang, Guo-Qiang Ding +1
We made a phase-resolved timing analysis of GRS 1915+105 in its ρ state and obtained detailed ρ cycle evolutions of the frequency, the amplitude and the coherence of low-frequency…
Determining the neutron star surface magnetic field strength of two Z sources
Guoqiang Ding, Chunping Huang, Yanan Wang
From the extreme position of disk motion, we infer the neutron star (NS) surface magnetic field strength B_0 of Z-source GX 17+2 and Cyg X-2. The inferred B_0 of GX 17+2 and Cyg X-…
