In this paper, we discuss a two-dimensional numerical study of isothermal high Mach number Bondi-Hoyle-Lyttleton flow around a small accretor. The flow is found to be unstable at high Mach numbers, with the instability appearing even for a larger accretor. The instability appears to be the unstable radial mode of the accretion column predicted by earlier analytic work.
Key words: accretion, accretion disks / hydrodynamics / instabilities
