摘要：
We present a nucleosynthesis study of the merger of a 0.4 M-circle dot helium white dwarf with a 0.8 M-circle dot carbon-oxygen white dwarf, coupling the thermodynamic history of Smoothed Particle Hydrodynamics particles with a post-processing nucleosynthesis code. The resulting chemical abundance pattern, particularly for oxygen and fluorine, is in qualitative agreement with the observed abundances in R Coronae Borealis stars.
