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.

New periodic variable stars coincident with ROSAT sources discovered using SuperWASP [PDF]
, 2007 We present optical lightcurves of 428 periodic variable stars coincident with ROSAT X-ray sources, detected using the first run of the SuperWASP photometric survey. Only 68 of these were previously recognised as periodic variables.

Three Additional Quiescent Low-Mass X-Ray Binary Candidates in 47 Tucanae [PDF]
, 2004 We identify through their X-ray spectra one certain (W37) and two probable (W17 and X4) quiescent low-mass X-ray binaries (qLMXBs) containing neutron stars in a long Chandra X-ray exposure of the globular cluster 47 Tucanae, in addition to the two ...

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.

Infrared identification of hard X-ray sources in the Galaxy [PDF]
, 2016 The nature of the low- to intermediate-luminosity (LX ∼ 1032–34 erg s−1) source population revealed in hard band (2–10 keV) X-ray surveys of the Galactic plane is poorly understood.

A Lack of Radio Emission from Neutron Star Low‐Mass X‐Ray Binaries [PDF]
The Astrophysical Journal, 2005 We report strict upper limits to the radio luminosities of three neutron star low-mass X-ray binaries obtained with the Very Large Array while they were in hard X-ray states as observed with the Rossi X-ray Timing Explorer: 1E 1724-307, 4U 1812-12, and SLX 1735-269.

Reflection and Timing Study of the Transient Black Hole X-Ray Binary MAXI J1803-298 with NuSTAR
The Astrophysical Journal, 2023 The transient black hole X-ray binary MAXI J1803−298 was discovered on 2021 May 1, as it went into outburst from a quiescent state. As the source rose in flux it showed periodic absorption dips and fit the timing and spectral characteristics of a hard ...

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.
