Relations between Timing Features and Colors in the X-Ray Binary 4U 0614+09 [PDF]

open access: yes, 2000
We study the correlations between timing and X-ray spectral properties in the low-mass X-ray binary 4U 0614+09 using a large (265 ks) data set obtained with the Rossi X-Ray Timing Explorer.

Disc–jet coupling in an atoll-type neutron star X-ray binary: 4U 1728–34 (GX 354–0) [PDF]

open access: yes, 2003
We have analysed 12 simultaneous radio (Very Large Array) and X-ray (RXTE) observations of the atoll-type X-ray binary 4U 1728-34, performed in two blocks in 2000 and 2001.

Physical parameters of the high-mass X-ray binary 4U1700-37 [PDF]

open access: yes, 2002
We present the results of a detailed non-LTE analysis of the ultraviolet and optical spectrum of the O6.5 Iaf + star HD 153919 - the mass donor in the high-mass X-ray binary 4U1700-37.

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

THE YOUNGEST KNOWN X-RAY BINARY: CIRCINUS X-1 AND ITS NATAL SUPERNOVA REMNANT [PDF]

open access: yes, 2013
Because supernova remnants are short-lived, studies of neutron star X-ray binaries within supernova remnants probe the earliest stages in the life of accreting neutron stars.

X-Ray and UV Observations of the Contact Binary KIC 9832227

open access: yesThe Astronomical Journal, 2023
We investigate the X-ray and UV emission from the contact binary star KIC 9832227, which was observed with XMM-Newton for one orbital cycle. The binary is detected with an average X-ray luminosity of 3.4 × 10 ^30 erg s ^−1 .

iShocks: X-ray binary jets with an internal shocks model [PDF]

open access: yes, 2009
In the following paper, we present an internal shocks model, iShocks, for simulating a variety of relativistic jet scenarios; these scenarios can range from a single ejection event to an almost continuous jet, and are highly user configurable.

SXP 1062, a young Be X-ray binary pulsar with long spin period - implications for the neutron star birth spin [PDF]

open access: yes, 2011
Context. The Small Magellanic Cloud (SMC) is ideally suited to investigating the recent star formation history from X-ray source population studies. It harbours a large number of Be/X-ray binaries (Be stars with an accreting neutron star as companion ...

A new radio census of neutron star X-ray binaries

open access: yesMonthly Notices of the Royal Astronomical Society, 2021
ABSTRACT We report new radio observations of a sample of 36 neutron star (NS) X-ray binaries, more than doubling the sample in the literature observed at current-day sensitivities. These sources include 13 weakly magnetized (B &lt; 1010 G) and 23 strongly magnetized (B ≥ 1010 G) NSs.
