Andrei M. Beloborodov CITA There are three classical modes of gas accretion: wind-fed, spherical, and disk. I will illustrate the three modes with the mass transfer in high-mass X-ray binaries. Then I will describe a new regime of mini-disk accretion. Observed X-ray sources associated with black holes are likely to accrete in this regime. Switching from one accretion mode to another can cause the observed spectral transitions.
