On the Putative Class of B[e] X-ray Binaries
نویسندگان
چکیده
We discuss the putative class of B[e] X-ray binaries, with reference to currently identified candidate systems, focusing on CI Cam and the newly identified class of highly obscured hard X-ray sources detected by INTEGRAL. We suggest that such a class will likely consist of two types of object in which the B[e] phenomenon is (i) intrinsic to the mass donor or (ii) a result of binarity. Finally, we discuss the difficulties inherent in observing B[e] X-ray binaries and the physical motivations for their study, which include the origin of the Galactic hard X-ray emission and the propagation of jets in dense media.

Forty Years of X-Ray Binaries
In 2012 it was forty years ago that the discovery of the first X-ray binary Centaurus X-3 became known. That same year it was discovered that apart from the High-Mass X-ray Binaries (HMXBs) there are also Low-Mass X-ray Binaries (LMXBs), and that Cygnus X-1 is most probably a black hole. By 1975 also the new class of Be/X-ray binaries was discovered. After this it took 28 years before ESAs INTE...
متن کاملUltraluminous X–ray Sources in External Galaxies
We investigate models for the class of ultraluminous non–nuclear X–ray sources (ULXs) seen in a number of galaxies and probably associated with star–forming regions. Models where the X–ray emission is assumed to be isotropic run into several difficulties. In particular formation of sufficient numbers of the required ultramassive black–hole X–ray binaries is problematic, and the likely transient...

Gamma-ray binaries have been uncovered as a new class of Galactic objects in the very high energy sky (> 100 GeV). The three systems known today have hard X-ray spectra (photon index ∼1.5), extended radio emission and a high luminosity in gamma-rays. Recent monitoring campaigns of LSI +61o303 in X-rays have confirmed variability in these systems and revealed a spectral hardening with increasing...
متن کاملSupergiant Fast X-ray Transients: a New Class of High Mass X-ray Binaries Unveiled by Integral
INTEGRAL monitoring of the Galactic Plane is revealing a growing number of recurrent X-ray transients, characterised by short outbursts with very fast rise times (∼ tens of minutes) and typical durations of a few hours. Here we show that several of these transients are associated with OB supergiants and hence define a new class of massive X-ray binaries which we call Supergiant Fast X-ray Trans...

In this work, the electrocatalytic oxidation of ethanol was studied in acidic media at the wholly electrosynthesized nanocomposites: platinum and its alloys (copper and nickel) anoparticles/reduced graphene oxide on the carbon-ceramic electrode (Pt/rGO/CCE, Pt-Cu/rGO/CCE, and Pt-Ni/rGO/CCE electrocatalysts). The electrosynthesized nanocomposites were characterized by scan...
