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.

New Results for Two Optically Faint Low-Mass X-Ray Binary Systems [PDF]
, 1997 We present optical photometry of the low-mass X-ray binary systems GX 349+2 (X1702-363) and Ser X-1 (X1837+049). Extensive VRI photometry of the faint optical counterpart (V = 18.4) to GX 349+2 reveals a period of 22.5 ± 0.1 hr and a half-amplitude of 0 ...

A 2.15 hr ORBITAL PERIOD FOR THE LOW-MASS X-RAY BINARY XB 1832-330 IN THE GLOBULAR CLUSTER NGC 6652 [PDF]
, 2012 We present a candidate orbital period for the low-mass X-ray binary (LMXB) XB 1832-330 in the globular cluster NGC 6652 using a 6.5 hr Gemini South observation of the optical counterpart of the system.

Analytical model of compact star in low-mass X-ray binary with de Sitter spacetime [PDF]
Research in Astronomy and Astrophysics, 2018 In this article, we suggest a Sitter model in favor of compact stars in low-mass X-ray binaries. Here, we have considered the presence of a cosmological constant (on a small scale) to investigate the stellar structure.

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.

The globular cluster mass/low mass X-ray binary correlation: implications for kick velocity distributions from supernovae [PDF]
, 2006 Optical and X-ray studies of six nearby galaxies show that the probability a globular cluster will be an X-ray source is consistent with being linearly proportional to its mass.

The IXPE View of Neutron Star Low-Mass X-ray Binaries
GalaxiesLow-mass X-ray binaries hosting weakly magnetized neutron stars (NS-LMXBs) are among the brightest sources in the X-ray sky. Since 2021, the Imaging X-ray Polarimetry Explorer (IXPE) has provided new measurements of the X-ray polarization of these sources.
