A Light Redback Companion of PSR J1622–0315 and Irradiation Power in Spider Systems
The Astrophysical Journal, 2023 We report optical observations of the millisecond pulsar binary system PSR J1622–0315 with the Lulin 1 m telescope in Taiwan and the Lijiang 2.4 m telescope in China between 2019 and 2021.

High-Frequency Variability in Neutron-Star Low-Mass X-ray Binaries [PDF]
, 2020 Binary systems with a neutron-star primary accreting from a companion star display variability in the X-ray band on time scales ranging from years to milliseconds. With frequencies of up to ~1300 Hz, the kilohertz quasi-periodic oscillations (kHz QPOs) represent the fastest variability observed from any astronomical object.

Insight-HXMT Detections of Hard X-Ray Tails in Scorpius X-1
The Astrophysical Journal, 2023 Using the observations of the high-energy detector of the Hard X-ray Modulation Telescope (Insight-HXMT) for Scorpius X-1 from 2017 to 2020, we search for hard X-ray tails in the X-ray spectra in ∼30–200 keV. The hard X-ray tails are found throughout the

Return of 4U 1730–22 after 49 yr Silence: The Outburst Properties Observed by NICER and Insight-HXMT
The Astrophysical Journal Letters, 2022 After 49 yr of quiescence, 4U 1730–22 became active and had two outbursts in 2021 and 2022; the onset and tail of the outbursts were observed by NICER, which give us a peerless opportunity to study the state transition and its underlying mechanism.

On the kinematics of the neutron star low mass X-ray binary Cen X-4 [PDF]
Astronomy & Astrophysics, 2005 We present the first determination of the proper motion of the neutron star low mass X-ray binary {Cen X-4} measured from relative astrometry of the secondary star using optical images at different epochs. We determine the Galactic space velocity components of the system and find them to be significantly different from the mean values that characterize

Long-term Quasiperiodicity in LMXB 4U 1636–536
The Astrophysical Journal, 2023 We present the results of the low-mass X-ray binary 4U 1636–536 study. We performed a temporal analysis of all available RXTE/All-Sky Monitor, RXTE/Proportional Counter Array, Swift/Burst Alert Telescope, and MAXI data collected until the middle of 2022.
