Black Hole Accretion Disc Instability and Soft X-Ray Transients
Time dependent behaviour of the accretion discs in low-mass X-ray binaries are studied as a model for soft X-ray transients. For relevant accretion rates, the disc suffers a thermal instability leading to intermittent accretion onto the central compact object. It is shown that the effect of X-ray irradiation of the outer disc by the central disc is small in the case of black hole binaries, and so the propagation of the cooling waves is not prevented.
