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 ...

Formation of Sco X-1 induced by anomalous magnetic braking of Ap/Bp stars
, 2017 Sco X-1 is the brightest persistent X-ray in the sky. It is generally believed that Sco X-1 is a low-mass X-ray binary containing a neutron star accreting from a low-mass donor star where mass transfer is driven by the magnetic braking. However, the mass

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

New Results for Two Optically Faint Low-Mass X-Ray Binary Systems [PDF]
, 1997 We present optical photometry of the low-mass X-ray binary systems GX 349+2 (X1702-363) and Ser X-1 (X1837+049). Extensive VRI photometry of the faint optical counterpart (V = 18.4) to GX 349+2 reveals a period of 22.5 ± 0.1 hr and a half-amplitude of 0 ...

Analytical model of compact star in low-mass X-ray binary with de Sitter spacetime [PDF]
Research in Astronomy and Astrophysics, 2018 In this article, we suggest a Sitter model in favor of compact stars in low-mass X-ray binaries. Here, we have considered the presence of a cosmological constant (on a small scale) to investigate the stellar structure.

Neutron Stars in X-ray Binaries and their Environments
, 2017 Neutron stars in X-ray binary systems are fascinating objects that display a wide range of timing and spectral phenomena in the X-rays. Not only parameters of the neutron stars, like magnetic field strength and spin period evolve in their active binary ...

On the Amplitude of Burst Oscillations in 4U 1636-54: Evidence for Nuclear Powered Pulsars [PDF]
, 1998 We present a study of 581 Hz oscillations observed during a thermonuclear X-ray burst from the low mass X-ray binary (LMXB) 4U 1636-54 with the Rossi X-ray Timing Explorer (RXTE).

Polarization properties of weakly magnetized neutron stars in low-mass X-ray binaries
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 ...

Bursts, eclipses, dips and a refined position for the luminous low-mass X-ray binary in the globular cluster Terzan 6 [PDF]
, 2003 GRS 1747-312 is a bright transient X-ray source in the globular cluster Terzan 6 with quasi-periodic outbursts approximately every 4.5 months. We carried out 2-60 keV target-of-opportunity observations during eight outbursts with the Proportional Counter
