A small nuclear-reaction network, individual alpha-capture reactions, and an expanding coordinate system are used to improve the two-dimensional hydrodynamic calculations of the core helium flash by Cole and Deupree (1980). The nuclear modifications allow the inclusion of neon photodisintegration, which limits the peak flash temperature to about two billion degrees, while the expanding coordinate system permits the flash to be followed for about 50 sec after the start of the violent runaway. The radial velocity time history at the expanding, outer boundary of the two-dimensional calculations is then used as an inner boundary condition for a one-dimensional hydrodynamic calculation of the envelope to determine whether mass loss occurs. It is found that the model, with an initial total mass of one solar mass, leaves a 0.65-solar mass remnant.
