Magnetic Inclination Evolution of Accreting Neutron Stars in Intermediate/Low-mass X-Ray Binaries [PDF]

open access: goldThe 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]

open access: green, 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

Bounds on Compactness for Low‐Mass X‐Ray Binary Neutron Stars from X‐Ray Burst Oscillations [PDF]

open access: bronze, 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.

Magnetic Braking with MESA Evolutionary Models in the Single Star and Low-mass X-Ray Binary Regimes [PDF]

open access: yesThe Astrophysical Journal, 2023
Magnetic braking has a prominent role in driving the evolution of close low-mass binary systems and heavily influences the rotation rates of low-mass F- and later-type stars with convective envelopes. Several possible prescriptions that describe magnetic

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]

open access: bronzeAstrophysical 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 ...

UPPER BOUNDS ONr-MODE AMPLITUDES FROM OBSERVATIONS OF LOW-MASS X-RAY BINARY NEUTRON STARS [PDF]

open access: bronze, 2013
We present upper limits on the amplitude of r-mode oscillations and gravitational-radiation-induced spin-down rates in low-mass X-ray binary neutron stars, under the assumption that the quiescent neutron star luminosity is powered by dissipation from a ...

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.

Low-Mass X-Ray Binaries with Strange Quark Stars [PDF]

open access: bronzePublications 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
