Discovery of the neutron star spin and orbital period from the Be/X-ray binary IGR J05414-6858 in the LMC
Discovery neutron star spin orbital the Be/X-ray binary IGR J05414-6858 the LMC

The number of known Be/X-ray binaries in the Large Magellanic Cloud is small compared to the observed population of the Galaxy or the Small Magellanic Cloud. The discovery of a system in outburst prov...
Modelling interaction of relativistic and non-relativistic winds in binary system PSR B1259-63/SS2883 - II. Impact of magnetization and anisotropy of the pulsar wind
HD – shock waves - pulsars: binaries
2011/10/19
In this paper, we present a numerical study of the properties of the flow produced by the collision of a magnetized anisotropic pulsar wind with its environment in binary system. We compare the impact...
RXTE Observations of the Low-Mass X-Ray Binary 4U 1608-522 in Upper-Banana State
RXTE Observations Low-Mass X-Ray Binary 4U 1608-522 Upper-Banana State
2011/10/11
To investigate the physics of mass accretion onto weakly-magnetized neutron stars, 95 archival RXTE datasets of an atoll source 4U 1608-522, acquired over 1996-2004 in so-called upper-banana state, we...

Discovery of GRB clusters allows us to determine coordinates and characteristics of their sources. The objects radiating GRBs are reliably identified with black hole binaries, including the Galactic b...
Discovery of a broad O VIII Ly alpha line in the ultra-compact X-ray binary 4U 1543-624

2010/11/15
We report the discovery of a broad emission feature at ∼ 0.7 keV in the spectra of the ultracompact X-ray binary 4U 1543-624, obtained with the high-resolution spectrographs of the
XMM-Newton a...
A Very Close Binary Black Hole in a Giant Elliptical Galaxy 3C 66B and its Black Hole Merger
Black Hole Giant Elliptical Galaxy 3C 66B Black Hole Merger
2010/11/15
In recent years the possibility of measuring the temporal change of radial and transverse position of sources in the sky in real time have become conceivable thanks to the thoroughly improved techniqu...
Estimation of compact binary coalescense rates from short gamma-ray burst redshift measurements
compact binary coalescense rates short gamma-ray
2010/11/12
Short gamma-ray bursts are believed to originate from the merger of two compact objects. If this scenario is correct, these bursts will be accompanied by the emission of strong gravitational waves, de...
Constraints of a pulsation frequency on stellar parameters in the eclipsing spectroscopic binary system: V577 Oph

2010/11/15
We present a preliminary spectroscopic analysis of the binary system V577Oph, observed during the summer of 2007 on the 2.6m NOT telescope on La Palma. We have obtained time series spectroscopic obser...
