Feeding Neutron Stars in High-Mass X-ray Binaries [PDF]
Proceedings of the International Astronomical Union, 2012 AbstractWe suggest that the Be/X-ray binary SXP 1062 and the supergiant fast X-ray transient AX J1841.0-0536 belong to accreting magnetars and anti-magnetars, respectively.

High-mass X-ray Binaries and OB-runaway Stars [PDF]
International Astronomical Union Colloquium, 2001 AbstractHigh-mass X-ray binaries (HMXBs) represent an important phase in the evolution of massive binary systems and provide fundamental information on the properties of the OB-star primaries and their compact secondaries (neutron star, black hole). Recent observations indicate that the neutron stars in some of these systems (Vela X-1, 4U 1700-37) are ...

Massive Stars and their Compact Remnants in High-mass X-ray Binaries
, 2005 In a high-mass X-ray binary (HMXB) a massive star interacts with a neutron-star or black-hole companion in various ways. The gravitational interaction enables the measurement of fundamental parameters such as the mass of both binary components, providing important constraints on the evolutionary history of the system, the equation of state of matter at

Modeling High Mass X-ray Binaries to Double Neutron Stars through Common Envelope Evolution [PDF]
The Astrophysical JournalAbstract We present detailed evolutionary simulations of wide binary systems with high-mass (8–20 M ⊙) donor stars and a 1.4 M ⊙ neutron star. Mass transfer in such binaries is dynamically unstable, and common envelope (CE) evolution is followed. We use a recently developed prescription to deal with CE

Rotation of the Mass Donors in High-mass X-ray Binaries and Symbiotic Stars
Acta Polytechnica CTU Proceedings, 2015 Our aim is to investigate the tidal interaction in High-mass X-ray Binaries and Symbiotic stars in order to determine in which objects the rotation of the mass donors is synchronized or pseudosynchronized with the orbital motion of the compact companion.

Exploration of spin-down rate of neutron stars in high-mass X-ray binaries [PDF]
Monthly Notices of the Royal Astronomical Society, 2016 We use the evolutionary population synthesis method to investigate the statistical properties of the wind-fed neutron star (NS) compact ($P_{\rm orb}<10$ days) high-mass X-ray binaries (HMXBs) in our Galaxy, based on different spin-down models. We find that the spin-down rate in the supersonic propeller phase given \textbf{by assuming that the ...

Early neutron star evolution in high-mass X-ray binaries [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT The application of standard accretion theory to observations of X-ray binaries provides valuable insights into neutron star (NS) properties, such as their spin period and magnetic field. However, most studies concentrate on relatively old systems, where the NS is in its late propeller, accretor, or nearly spin equilibrium phase.

High Resolution and Broad Band Spectra of Low Mass X-ray Binaries: a Comparison between Black Holes and Neutron Stars [PDF]
Chinese Journal of Astronomy and Astrophysics, 2006 A common question about compact objects in high energy astrophysics is whether it is possible to distinguish black hole from neutron star systems with some other property that is not the mass of the compact object. Up to now a few characteristics have been found which are typical of neutron stars (like quasi periodic oscillations at kHz frequencies or ...

MEASUREMENT OF THE RADIUS OF NEUTRON STARS WITH HIGH SIGNAL-TO-NOISE QUIESCENT LOW-MASS X-RAY BINARIES IN GLOBULAR CLUSTERS [PDF]
The Astrophysical Journal, 2013 This paper presents the measurement of the neutron star (NS) radius using the thermal spectra from quiescent low-mass X-ray binaries (qLMXBs) inside globular clusters (GCs). Recent observations of NSs have presented evidence that cold ultra dense matter -- present in the core of NSs -- is best described by "normal matter" equations of state (EoSs ...
