                         ionized Bondi accretion on to a massive object in the specific 
                         context of accretion on to a young stellar object. We first derive 
                         a new analytic expression for a steady-state two-temperature 
                         solution that predicts the existence of compact and hypercompact H 
                         II regions. We then show that this solution is only marginally 
                         stable if ionization is treated self-consistently. This leads to a 
                         recurring collapse of the H II region over time. We derive a 
                         semi-analytic model to explain this instability, and test it using 
                         spatially converged 1D radiation hydrodynamical simulations. We 
                         discuss the implications of the 1D instability on 3D radiation 
                         hydrodynamics simulations of supersonic accreting flows.",
