Revealing the Spectral State Transition of the Clocked Burster, GS 1826-238, with NuSTAR StrayCats
The Astrophysical Journal, 2023 We present the long-term analysis of GS 1826-238, a neutron star X-ray binary known as the Clocked Burster , using data from NuSTAR StrayCats. StrayCats, a catalog of NuSTAR stray light data, contains data from bright, off-axis X-ray sources that have ...

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

Disk Instability in Wide Neutron Star Low‐Mass X‐Ray Binaries [PDF]
The Astrophysical Journal, 1998 Conditions for disk instability in low-mass X-ray binaries (LMXBs) have been recently considered with X-ray irradiation of the disk included. Conservative evolution was generally assumed, which, however, fails in wide LMXBs with a neutron star primary (NLMXBs).

THE CASE FOR A LOW MASS BLACK HOLE IN THE LOW MASS X-RAY BINARY V1408 AQUILAE (= 4U 1957+115) [PDF]
, 2015 There are few confirmed black holes with a mass of less ∼ 4 M ⊙ ?> and no neutron stars with masses greater than ∼ 2 M ⊙ ?> , creating a gap in the observed distribution of compact star masses.

Comparison of the H-alpha circumstellar disks in Be/X-ray binaries and Be stars [PDF]
, 2000 We present a comparative study of the circumstellar disks in Be/X-ray binaries and isolated Be stars based upon the H-alpha emission line. From this comparison it follows that the overall structure of the disks in the Be/X-ray binaries is similar to the disks of other Be stars, i.e. they are axisymmetric and rotationally supported.

Excitation of Neutron Star f-mode in Low Mass X-ray Binaries [PDF]
Journal of Physics: Conference Series, 2006 Neutron Stars (NSs) present a host of pulsation modes. Only a few of them, however, is of relevance from the gravitational wave (GW) point of view. Among the various possible modes the pulsation energy is mostly stored in the f-mode in which the fluid parameters undergo the largest changes.

Investigating the Ultracompact X-Ray Binary Candidate SLX 1735-269 with NICER and NuSTAR
The Astrophysical JournalWe present two simultaneous NICER and NuSTAR observations of the ultracompact X-ray binary (UCXB) candidate SLX 1735−269 while the source was in two different spectral states. Using various reflection modeling techniques, we find that xillverCO , a model

News on the X-ray emission from hot subdwarf stars
Open Astronomy, 2017 In latest years, the high sensitivity of the instruments on-board the XMM-Newton and Chandra satellites allowed us to explore the properties of the X-ray emission from hot subdwarf stars.

The high energy X-ray probe (HEX-P): a new window into neutron star accretion
Frontiers in Astronomy and Space Sciences, 2023 Accreting neutron stars (NSs) represent a unique laboratory for probing the physics of accretion in the presence of strong magnetic fields (B ≳ 108 G).
