Superorbital Phase Evolution and Identification of New Anomalous Low State Candidates for Her X-1
Yi Chou, Jun-Lei Wu
The 35-day superorbital modulation of the X-ray binary Her X-1 was systematically investigated using a 35-year multi-instrument X-ray observational baseline. We developed a Rank-Se…
Superorbital Phase Evolution and a Soft-Hard X-ray Phase Shift in LMC X-4
Yi Chou
The superorbital period of LMC X-4 is among the most stable known in Roche-lobe overflow, high-mass X-ray binaries. We analyzed 33 years of monitoring data from the Compton Gamma R…
Updated Orbital Ephemeris and Detection of Superhump Modulation in X-ray Band for the Ultra-Compact Low Mass X-ray Binary 4U 1820-30
Yi Chou, Yao-Wun Jhang
The 4U 1820-30 is a ultra-compact low mass X-ray binary (LMXB) near the center of the globular cluster NGC 6624. Its negative orbital period derivative, observed from the phase evo…
Detection of Millihertz Quasi-Periodic Oscillations in the X-Ray Binary 1RXS J180408.9342058
Kaho Tse, Duncan K. Galloway, Yi Chou +2
Millihertz quasi-periodic oscillations (mHz QPOs) observed in neutron-star low-mass X-ray binaries (NS LMXBs) are generally explained as marginally stable thermonuclear burning on…
Updated Spin and Orbital Parameters and Energy Dependent Pulse Behaviors of the Accreting Millisecond X-ray Pulsar IGR J175912342
Kaho Tse, Yi Chou, Hung-En Hsieh
We present our works in updating the spin and orbital parameters for the newly discovered accreting millisecond X-ray pulsar (AMXP) IGR J175912342 through pulsar timing and anal…
Phase-resolved analyses of mHz quasi-periodic oscillations in 4U 1636-53 using Hilbert-Huang transform
Hung-En Hsieh, Yi Chou
We present phase-resolved spectroscopies based on Hilbert-Huang transform (HHT) for millihertz quasi-periodic oscillations (mHz QPOs) in 4U 1636-536. This ~8 mHz QPO can be detecte…
