Astronomy & AstrophysicsMillisecond pulsars (MSPs) are laboratories for stellar evolution, strong gravity, and ultra-dense matter. Although MSPs are thought to originate in low-mass X-ray binaries (LMXBs), approximately 27% do not have a binary companion, and others are found ...

The secondary stars in cataclysmic variables and low-mass X-ray binaries [PDF]
Monthly Notices of the Royal Astronomical Society, 1998 We critically re-examine the available data on the spectral types, masses and radii of the secondary stars in cataclysmic variables (CVs) and low-mass X-ray binaries (LMXBs), using the new catalogue of Ritter & Kolb (1998) as a starting point. We find there are 55 reliable spectral type determinations and only 14 reliable mass determinations of CV ...

Compact Stars in low-mass X-ray binaries
, 2014 We propose a model for compact stars in low-mass X-ray binaries(LMXBs) namely KS 1731-260, EXO 1745-248 and 4U 1608-52. Here we investigate the physical phenomena of a compact star in the LMXBs. Using our model, we have calculated central density, surface density, mass(M) and red-shift for the above mentioned compact stars, which is very much ...

Quark stars in Low-Mass X-ray Binaries: for and against
, 2000 It has been suggested that both X-ray bursters and millisecond radio pulsars may be strange (quark) stars, rather than neutron stars. Confirming (or rejecting) this suggestion may require knowing what role strong-field effects of general relativity play in the accretion flow of the compact X-ray source in low-mass X-ray binaries (LMXBs). We discuss the

X-Ray Polarization Study of the Neutron Star Low-mass X-Ray Binary GX 349+2
The Astrophysical JournalWe report the first X-ray polarimetric results of the neutron star (NS) low-mass X-ray binary Z-source GX 349+2 using the Imaging X-ray Polarimetry Explorer (IXPE). We discovered that the X-ray source was polarized at a polarization degree of PD = 1.1% ±

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.

Search for intermittent X-ray pulsations from neutron stars in low-mass X-ray binaries [PDF]
Publications of the Astronomical Society of Australia, 2021 AbstractWe present the results of our extensive binary orbital motion corrected pulsation search for 13 low-mass X-ray binaries. These selected sources exhibit burst oscillations in X-rays with frequencies ranging from 45 to 1 122 Hz and have a binary orbital period varying from 2.1 to 18.9 h.

Chemical abundances of secondary stars in low mass X-ray binaries [PDF]
Proceedings of the International Astronomical Union, 2006 AbstractLow mass X-ray binaries (LMXBs) offer us an unique opportunity to study the formation processes of compact objects. Secondary stars orbiting around either a black hole or a neutron star could have captured a significant amount of the ejected matter in the supernova explosions that most likely originated the compact objects.

Spin evolution of neutron stars in transient low-mass X-ray binaries [PDF]
Monthly Notices of the Royal Astronomical SocietyABSTRACT Millisecond pulsar + helium white dwarf (MSP + He WD) binaries are thought to have descended from neutron star low-mass X-ray binaries (NS LMXBs). The NSs accreted from the progenitors of the WDs and their spin periods were accordingly accelerated to the equilibrium periods of order milliseconds.
