Magnetic Inclination Evolution of Accreting Neutron Stars in Intermediate/Low-mass X-Ray Binaries [PDF]
The Astrophysical Journal, 2023 The magnetic inclination angle χ , namely the angle between the spin and magnetic axes of a neutron star, plays a vital role in its observational characteristics. However, there are few systematic investigations of its long-term evolution, especially for

Accreting Neutron Stars in Low-Mass X-Ray Binary Systems [PDF]
, 2008 Using the Rossi X-ray Timing Explorer (RossiXTE ), astronomers have discovered that disk-accreting neutron stars with weak magnetic fields produce three distinct types of high-frequency X-ray oscillations. These oscillations are powered by release of the

Low-Mass X-Ray Binaries with Strange Quark Stars [PDF]
Publications of the Astronomical Society of the Pacific, 2012 Strange quark stars (SSs) may originate from accreting neutron stars (NSs) in low-mass X-ray binaries (LMXBs). Assuming that conversion of NS matter to SSs occurs when the core density of accreting NS reaches to the density of quark deconfinement, $\sim 5 _0$, where $ _0\sim 2.7\times 10^{14}$g cm$^{-3}$ is nuclear saturation density, we investigate

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 ...

Quasi-Periodic Oscillations from Low-mass X-Ray Binaries with Neutron Stars [PDF]
AIP Conference Proceedings, 2004 Before the launch of the Rossi X-ray Timing Explorer (RXTE) it was recognized that neutron star accretion disks could extend inward to very near the neutron star surface, and thus be governed by millisecond timescales. Previous missions lacked the sensitivity to detect them. The kilohertz quasi-periodic oscillations (QPO) that RXTE discovered are often,

Bounds on Compactness for Low‐Mass X‐Ray Binary Neutron Stars from X‐Ray Burst Oscillations [PDF]
, 2002 We have modeled X-ray burst oscillations observed with the Rossi X-Ray Timing Explorer from two low-mass X-ray binaries (LMXB): 4U 1636-53 with a frequency of 580 Hz and 4U 1728-34 at a frequency of 363 Hz.

Compact Stars in low-mass X-ray binaries [PDF]
, 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 ...

The Equation of State and Some Key Parameters of Neutron Stars: Constraints from GW170817, the Nuclear Data, and the Low-mass X-Ray Binary Data [PDF]
Astrophysical Journal, 2019 In this work we parameterize the equation of state of dense neutron star (NS) matter with four pressure parameters of and then set the combined constraints with the data of GW170817 and the data of six low-mass X-ray binaries (LMXBs) with thermonuclear ...

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.

Quiescent thermal emission from neutron stars in low-mass X-ray binaries [PDF]
Astronomy & Astrophysics, 2015 Context. We monitored the quiescent thermal emission from neutron stars in low-mass X-ray binaries after active periods of intense activity in X-rays (outbursts). Aims. The theoretical modeling of the thermal relaxation of the neutron star crust may be used to establish constraints on the crust composition and transport properties, depending on the ...
