Black hole binaries and microquasars
A microquasar, the smaller version of a quasar, is a compact region surrounding a stellar black hole with a mass several times that of its companion star. The matter being pulled from the companion star forms an accretion disk around the black hole. This accretion disk may become so hot, due to friction, that it begins to emit X-rays. The disk also projects narrow streams or "jets" of subatomic particles at near-light speed, generating a strong radio wave emission. WebFeb 27, 2024 · from the black-hole X-ray binaries (BHXRBs) [3–5] and the AGNs have shown that they are mainly due to the mass accretion onto the compact object (black hole or neutron star). The accreted matter comes from a companion (donor) star which is often a nearby main sequence star [6,7]. Thus, the inflow (from the companion star) into the …

WebThe end points of each jet are characterized by radio frequency emission. Stellar X-ray binaries which have black holes and radio emissions resulting from relativistic jets are sometimes referred to as to as microquasars or radio-jet X-ray binaries (Farlex Inc. 2004) to distinguish them from other stellar X-ray binaries.
WebThe discovery of microquasars (Margon, 1994; Mirabel et al. 1992) with apparent superluminal motions (Mirabel & Rodríguez, 1994) has opened new perspectives for the astrophysics of black holes (Mirabel & Rodríguez, 1999 for a review). These scaled-down versions of quasars are believed to be powered by spinning black holes with masses of … WebThe recent observations have indicated that the superluminal jets probably are the common nature of the black hole X-ray binaries and, in part, of the neutron star binary sources. The recent development in observational techniques has made it possible to study detailed feature of jet phenomena.
WebThese diagrams were transformed in physical units with X-ray satellites responses and defined over two different energy ranges. These diagrams - the X-ray equivalent of the stellar evolution HR diagrams - aimed at reproducing and stuying the hysteresis cycles of microquasars (stellar binaries containing a black hole). Voir moins Webabout ∼ 50 sources among the ∼ 280 known X-ray binaries (Liu et al. 2000; Liu et al. 2001).
