Why Do Black--Hole X-ray Binaries Tend to Be Transient? [PDF]

open access: yes, 1999
Black hole X-ray binaries are transient probably because their discs are subject to the same thermal-viscous instability which is present in dwarf nova binary systems.

Beam Pattern Evolution of Accreting X-Ray Pulsar 1A 0535+262 during Its 2020 Giant Outburst

open access: yesThe Astrophysical Journal, 2023
We report on pulse profile decomposition analysis of bright transient X-ray pulsar 1A 0535+262 using broadband Insight-HXMT observations during a giant outburst of the source in 2020.

Back to Business: SLX 1746–331 after 13 Years of Silence

open access: yesThe Astrophysical Journal, 2023
The black hole candidate system SLX 1746–331 was back to business in 2023, after a long silence of roughly 13 years. An outburst was observed thoroughly by Insight-HXMT and NICER.

Generation of X-Ray Fluctuations in X-Ray Binaries [PDF]

open access: yesInternational Astronomical Union Colloquium, 1996
AbstractShort-term aperiodic fluctuations with 1/f-like power spectral density (PSD), where f is the frequency, are characteristics of X-ray radiation from X-ray binaries. To investigate a mechanism creating fluctuations, we construct a cellular-automaton model for accretion disks based on the concept of self organized criticality (SOC). In this model,

X-RAY POLARIZATION FROM HIGH-MASS X-RAY BINARIES [PDF]

open access: yesThe Astrophysical Journal, 2015
X-ray astronomy allows study of objects which may be associated with compact objects, i.e. neutron stars or black holes, and also may contain strong magnetic fields. Such objects are categorically non-spherical, and likely non-circular when projected on the sky.

A Dragon Out of Breath? Monitoring High-velocity Outflows from the High-mass Gamma-Ray Binary LS 2883/PSR B1259–63 During the 2017–2021 Binary Cycle

open access: yesThe Astrophysical Journal, 2023
Observations of the high-mass gamma-ray binary LS 2883/PSR B1259–63 with the Chandra X-ray Observatory during the 2011–2014 and 2014–2017 binary cycles have shown X-ray-emitting clumps, presumably ejected from the binary during periastron passages. These

Populating the Galaxy with low-mass X-ray binaries [PDF]

open access: yes, 2006
We perform binary population synthesis calculations to investigate the incidence of low-mass X-ray binaries and their birth rate in the Galaxy. We use a binary evolution algorithm that models all the relevant processes including tidal circularization and

The eclipsing X-ray pulsar X-7 in M33 [PDF]

open access: yes, 1998
Using our extensive ROSAT X-ray observations of M33, we confirm a 3.45 day eclipse period for the Einstein source X-7 (Larson & Schulman, 1997) and discover evidence for a 0.31-s pulse period.
