Long-term Periodicities of Cataclysmic Variables with Synoptic Surveys
Michael Ting-Chang Yang, Yi Chou, Chow-Choong Ngeow +12
A systematic study on the long-term periodicities of known Galactic cataclysmic variables (CVs) was conducted. Among 1580 known CVs, 344 sources were matched and extracted from the…
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…
