A Lack of Radio Emission from Neutron Star Low‐Mass X‐Ray Binaries [PDF]

open access: yesThe 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.

High-Frequency Variability in Neutron-Star Low-Mass X-ray Binaries [PDF]

open access: yes, 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.

On the kinematics of the neutron star low mass X-ray binary Cen X-4 [PDF]

open access: yesAstronomy & 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

The IXPE View of Neutron Star Low-Mass X-ray Binaries

open access: yesGalaxies
Low-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.

Disk Instability in Wide Neutron Star Low‐Mass X‐Ray Binaries [PDF]

open access: yesThe Astrophysical Journal, 1998
Conditions for disk instability in low-mass X-ray binaries (LMXBs) have been recently considered with X-ray irradiation of the disk included. Conservative evolution was generally assumed, which, however, fails in wide LMXBs with a neutron star primary (NLMXBs).
