Accretion Disk Wind of Hercules X-1 during the Short High State
The Astrophysical Journal, 2023 Hercules X-1 is a nearly edge-on X-ray binary with a warped, precessing accretion disk, which manifests through a 35-day cycle of alternating High and Low flux states.

The globular cluster mass/low mass X-ray binary correlation: implications for kick velocity distributions from supernovae [PDF]
, 2006 Optical and X-ray studies of six nearby galaxies show that the probability a globular cluster will be an X-ray source is consistent with being linearly proportional to its mass.

Formation of Ultracompact X-Ray Binaries in Dense Star Clusters [PDF]
The Astrophysical Journal, 2005 Bright, ultracompact X-ray binaries observed in dense star clusters, such as Galactic globular clusters, must have formed relatively recently, since their lifetimes as persistent bright sources are short (e.g., ~10^8 yr above 10^36 erg/s for a 1.4 Msun neutron star accreting from a degenerate helium companion with an initial mass of ~0.2 Msun ...

Advanced Engineering Materials, EarlyView.Incorporating nanosized silver into titanium for antimicrobial materials exploits the metastable miscibility gap between silver and titanium. Silver nanoparticles are synthesized via pulsed laser ablation in liquid. Silver addition refines the microstructure, increases hardness by 30%, and reduces Staphylococcus capitis microbial adhesion by 70%, with ...

Discovery of a New Phase-transient Cyclotron Line in A0535+26: Constraints on the Accretion Geometry
The Astrophysical JournalIn 2020 November, A0535+26 underwent one of its brightest outbursts, reaching nearly 12 Crab in X-ray flux. Observed by Insight-HXMT, NuSTAR, NICER, and AstroSat, this event provided valuable insights into Be/X-ray binaries.

Insight-HXMT Views Her X-1: Probing the Dependence of the Cyclotron Line Energy on Flux and Time
The Astrophysical Journal, 2023 Recent observations of Her X-1 with NuSTAR (as well as with INTEGRAL, Swift, and Astrosat) have provided evidence that the nearly 20 yr-long decay of the cyclotron line energy since ∼1994 has ended and that a stable value has replaced the decay.

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

Three Additional Quiescent Low-Mass X-Ray Binary Candidates in 47 Tucanae [PDF]
, 2004 We identify through their X-ray spectra one certain (W37) and two probable (W17 and X4) quiescent low-mass X-ray binaries (qLMXBs) containing neutron stars in a long Chandra X-ray exposure of the globular cluster 47 Tucanae, in addition to the two ...
