Masses of Neutron Stars in X-ray Binary Systems [PDF]
Symposium - International Astronomical Union, 1981 The masses of 6 neutron stars have now been established through studies of binary X-ray and radio pulsars. All of the masses are found to be consistent with, but not necessarily constrained to, the range 1.2–1.6 M⊙. In this talk we discuss the methods and assumptions used in determining the masses of neutron stars in binary X-ray pulsar systems.

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

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

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.

Strong X-ray variability in the quiescent state of the neutron star low-mass X-ray binary EXO 1745-248 [PDF]
, 2011 The transient neutron star low-mass X-ray binary EXO 1745−248, located in the globular cluster Terzan 5, was detected during its quiescent state with Chandra in 2003.

Low-level accretion in neutron star X-ray binaries [PDF]
Monthly Notices of the Royal Astronomical Society, 2015 We search the literature for reports on the spectral properties of neutron-star low-mass X-ray binaries when they have accretion luminosities between 1E34 and 1E36 ergs/s. We found that in this luminosity range the photon index (obtained from fitting a simple absorbed power-law in the 0.5-10 keV range) increases with decreasing 0.5-10 keV X-ray ...

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

A Comparison of Millisecond Pulsar Populations between Globular Clusters and the Galactic Field
The Astrophysical Journal, 2023 We have performed a systematic study of the rotational, orbital, and X-ray properties of millisecond pulsars (MSPs) in globular clusters (GCs) and compared their nature with those of the MSPs in the Galactic field (GF).
