QPOs in Cataclysmic Variables and in X-ray Binaries
Recent observations, reported by Warner and Woudt, of Dwarf Nova Oscillations (DNOs) exhibiting frequency drift, period doubling, and 1:2:3 harmonic structure, can be understood as disc oscillations that are excited by perturbations at the spin frequency of the white dwarf or of its equatorial layers. Similar quasi-periodic disc oscillations in black hole low-mass X-ray binary (LMXB) transients...
متن کاملForty 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 کاملTransient X-ray Binaries in Elliptical Galaxies
Chandra observations of elliptical galaxies have revealed large numbers of Low Mass X-ray Binaries (LMXBs) accreting at rates > 10M⊙ yr−1. One scenario which generates this Ṁ from an old stellar population is nuclear driven mass transfer onto a neutron star or black hole from a Roche lobe filling red giant. However, in our Galaxy, most of these systems accrete sporadically as transients due to ...
متن کاملTransient neutron star X{ray binaries with Simbol-X
We present a brief overview of test-bed observations on accreting neutron star binaries for the Simbol-X mission. We show that Simbol-X will provide unique observations able to disclose the physical mechanisms responsible for their high energy emission.
متن کاملThe Formation of Low–mass Transient X–ray Binaries
We consider constraints on the formation of low–mass X–ray binaries containing neutron stars (NLMXBs) arising from the presence of soft X–ray transients among these systems. For a neutron star mass M1 ≃ 1.4M⊙ at formation, we show that in short– period (∼< 1− 2 d) systems driven by angular momentum loss these constraints require the secondary at the beginning of mass transfer to have a mass 1.3...
