Polarization properties of weakly magnetized neutron stars in low-mass X-ray binaries [PDF]
Monthly Notices of the Royal Astronomical Society, 2022 ABSTRACT X-ray polarimetry missions like Imaging X-ray Polarimetry Explorer will be able to measure for the first time the polarization properties of accreting, weakly magnetized neutron stars in low-mass X-ray binaries. In this work, we present simulations of the expected X-ray polarized signal, including the coronal emission for ...

Accretion Disk Boundary Layers around Neutron Stars: X‐Ray Production in Low‐Mass X‐Ray Binaries [PDF]
The Astrophysical Journal, 2001 We present solutions for the structure of the boundary layer where the accretion disk meets the neutron star, which is expected to be the dominant source of high-energy radiation in low-mass X-ray binaries which contain weakly magnetized accreting neutron stars.

X-Ray and Radio Polarimetry of the Neutron Star Low-mass X-Ray Binary 4U 1728–34
The Astrophysical JournalWe report the first X-ray and radio polarimetric results of the neutron star (NS) low-mass X-raydis binary atoll-source 4U 1728−34 using the Imaging X-ray Polarimetry Explorer (IXPE) and Australia Telescope Compact Array.

A New Comptonization Model for Weakly Magnetized, Accreting Neutron Stars in Low-Mass X-Ray Binaries [PDF]
The Astrophysical Journal, 2008 We developed a new model for the X-ray spectral fitting \xspec package which takes into account the effects of both thermal and dynamical (i.e. bulk) Comptonization. The model consists of two components: one is the direct blackbody-like emission due to seed photons which are not subjected to effective Compton scattering, while the other one is a ...

Spectral Energy Distributions of Southern Binary X-Ray Sources
The Astrophysical Journal Supplement Series, 2023 The rapid variability of X-ray binaries (XRBs) produces a wide range of X-ray states that are linked to activity across the electromagnetic spectrum. It is particularly challenging to study a sample of sources large enough to include all types in their ...

An Optically Discovered Outburst from XTE J1859+226
The Astrophysical Journal, 2023 Using the Zwicky Transient Facility, in 2021 February we identified the first known outburst of the black hole X-ray transient XTE J1859+226 since its discovery in 1999. The outburst was visible at X-ray, UV, and optical wavelengths for less than 20 days,

Donors of Persistent Neutron-Star Low-Mass X-Ray Binaries [PDF]
Publications of the Astronomical Society of the Pacific, 2012 Properties of X-ray luminosities in low-mass X-ray binaries (LMXBs) mainly depend on donors. We have carried out a detailed study of donors in persistent neutron-star LMXBs (PLMXBs) by means of a population synthesis code. PLMXBs with different donors have different formation channels.

PSR J1953+1844 Probably Being the Descendant of an Ultracompact X-Ray Binary
The Astrophysical Journal Letters, 2023 PSR J1953+1844 (i.e., M71E) is a millisecond pulsar in a 53 minute binary orbit discovered by the Five-hundred-meter Aperture Spherical radio Telescope. The mass function from pulsar timing is 2.3 × 10 ^−7 M _⊙ .
