Abstract: |
We present a nucleosynthesis study of the merger of a 0.4 M☉
helium white dwarf with a 0.8 M☉ 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. |
