Black hole X-ray binaries LMC X–1 and X–3: observations confront spectral models
LMC X–1 LMC X–3
2014/12/24
We present a comprehensive spectral analysis of black hole X-ray binaries, LMC X–1 and X–3, based on BeppoSAX observations. We test both the multicolour disc plus power-law (MCD+PL) model and a newly ...
The Search for High-Mass X-ray Binaries in the Phoenix Dwarf Galaxy
High-Mass X-ray Binaries Phoenix Dwarf Galaxy
2012/2/23
We report on the first X-ray images of the Phoenix dwarf galaxy, taken with \emph{XMM-Newton} in July 2009. This local group dwarf galaxy shares similarities with the Small Magellanic Cloud (SMC) incl...
Oscillations of relativistic axisymmetric tori and implications for modelling kHz-QPOs in neutron-star X-ray binaries
X-rays: binaries – relativity – stars: neutron
2011/10/8
We perform a global linear perturbative analysis, and investigate the oscillation properties of relativistic, non-selfgravitating tori orbiting around neutron stars in the slow rotation limit approxim...
Revealing the physics of r-modes in low-mass X-ray binaries
Revealing the physics of r-modes in low-mass X-ray binaries
2011/10/21
We consider the astrophysical constraints on the gravitational-wave driven r-mode instability in accreting neutron stars in low-mass X-ray binaries. We use recent results on superfluid and superconduc...
Comparing the Accretion Disk Evolution of Black Hole and Neutron Star X-ray Binaries from Low to Super-Eddington Luminosity
Accretion Disk Evolution Neutron Star X-ray Binaries Super-Eddington Luminosity
2011/10/21
Low-mass X-ray binaries (LMXBs) are systems in which a low-mass companion transfers mass via Roche-lobe overflow onto a black hole (BH) or a weakly magnetized neutron star (NS). It is believed that bo...
Discovery and identification of infrared counterpart candidates of four Galactic centre low mass X-ray binaries
X-rays: binaries – infrared: stars – X-rays: individuals: XTE J1637− 498, IGRJ17379− 3747, IGR J17585− 3057, GX9+1
2011/9/30
The near infrared (nIR)/optical counterparts of low mass X-ray binaries (LMXBs) are often observationally dim and reside in high source density fields which make their identification problematic; howe...
Highly absorbed X-ray binaries in the Small Magellanic Cloud
galaxies: Small Magellanic Cloud – stars: emission–line, Be – X-rays: binaries
2011/9/29
Many of the high mass X-ray binaries (HMXRBs) discovered in recent years in our Galaxy are characterized by a high absorption, most likely intrinsic to the system, which hampers their detection at the...

Distribution High Mass X-ray Binaries Milky Way
2011/9/27
The INTEGRAL satellite, observing the sky at high energy, has quadrupled the number of supergiant X-ray Binaries known in the Galaxy and has revealed new populations of previously hidden High Mass X-r...
Nature, formation and evolution of High Mass X-ray Binaries
Nature formation evolution Mass X-ray Binaries
2011/9/27
The aim of this review is to describe the nature, formation and evolution of the three kinds of high mass X-ray binary (HMXB) population: i. systems hosting Be stars (BeHMXBs), ii. systems accreting t...
Orbital Period Determinations for Four SMC Be/X-ray Binaries
Orbital Period Determinations SMC Be/X-ray Binaries
2011/1/11
We present an optical and X-ray study of four Be/X-ray binaries located in the Small Magellanic Cloud (SMC). OGLE I-band data of up to 11 years of semi-continuous monitoring has been analysed for SMC ...
High Mass X-ray Binaries in the NIR : Orbital solutions of two highly obscured systems
High Mass X-ray Binaries；the NIR
2011/1/13
The maximum mass of a neutron star (NS) is poorly defined. Theoretical attempts to define this mass have thus far been unsuccessful. Observational results currently provide the only means of narrowing...
New Galactic High Mass X-ray Binaries discovered with INTEGRAL
High Energy Astrophysical Phenomena (astro-ph.HE)
2010/12/28
I will review the main observational properties of the new Galactic High Mass X-ray Binaries discovered by the INTEGRAL satellite in the hard energy range 17-100 keV.
