X-ray Binaries Research Group

The X-ray Binaries group is active in research in Galactic X-Ray Astronomy, in the fields of binary systems containing a neutron star or a black hole accreting mass from a companion.

Our interests are in the processes that produce X-ray emission and of the geometry, size and physical conditions in the emission regions, particularly in accretion disc coronae and on the surface of the neutron star, as well as the fundamental physics taking place in sources of widely varying luminosities, including the launching of jets. These aspects are still poorly understood. This work has been carried out using the satellite observatories: Exosat, Rosat, Asca, BeppoSAX, Rossi-XTE, XMM-Newton, Chandra, Suzaku and Swift.

The Sky seen in X-rays is filled with binary systems containing neutron stars, black holes and white dwarfs together with X-ray bursters, pulsars, supernova remnants and active galactic nuclei.

The X-ray Binaries are among the brightest sources in the Sky. They consist of a neutron star or black hole in binary orbit with a normal star, in which matter is being transferred gravitationally from the companion star to the compact object releasing huge amount of energy in the X-ray band.
