Orbital and Spin Parameter Variations of Partial Eclipsing Low Mass X-ray Binary X 1822-371
Yi Chou, Hung-En Hsieh, Chin-Ping Hu +2
We report our measurements for orbital and spin parameters of X 1822-371 using its X-ray partial eclipsing profile and pulsar timing from data collected by the Rossi X-ray Timing E…
Characterizing Intermittency of 4-Hz Quasi-periodic Oscillation in XTE J1550-564 using Hilbert-Huang Transform
Yi-Hao Su, Yi Chou, Chin-Ping Hu +1
We present the time-frequency analysis results based on the Hilbert-Huang transform (HHT) for the evolution of a 4-Hz low-frequency quasi-periodic oscillation (LFQPO) around the bl…
Tracking the Evolution of QPO in RE J1034+396 Using the Hilbert-Huang Transform
Chin-Ping Hu, Yi Chou, Ting-Chang Yang +1
RE J1034+396, a narrow-line Seyfert-1 active galactic nucleus (AGN), is the first example of AGNs that exhibited a nearly coherent quasi-periodic oscillation (QPO) for the data col…
Superorbital Phase-Resolved Analysis of SMC X-1
Chin-Ping Hu, Yi Chou, Ting-Chang Yang +1
The high-mass X-ray binary SMC X-1 is an eclipsing binary with an orbital period of 3.89 d. This system exhibits a superorbital modulation with a period varying between ~40 d and ~…
Time-Frequency Analysis of Superorbital Modulation of X-ray Binary SMC X-1 by Hilbert-Huang Transform
Chin-Ping Hu, Yi Chou, Ming-Chya Wu +2
The high-mass X-ray binary (HMXB) SMC X-1 exhibits a superorbital modulation with a dramatically varying period ranging between ~40 d and ~60 d. This research studies the time-freq…
