| Abstract | Nova outbursts are the results of thermonuclear runaways, which occur when sufficient material accretes on the surfaces of white dwarfs (WDs). Using the MESA code, we construct a detailed grid for carbon-oxygen and oxygen-neon-magnesium novae. By employing population synthesis methods, we conduct a statistical analysis of the distribution of novae in the Milky Way. In our models, on average, a typical nova system may undergo about 8000 eruptions and the Galactic nova rate is similar to 130 yr(-1). The C, N, and O elements in nova ejecta are strongly affected by the mixing degree between WD core and accreted material. Our results show that the average value of C-12/C-13 in nova ejecta is about an order of magnitude lower than that on the surface of a red giant, that for O-16/O-17 is about 5 times lower, and that for N-14/N-15 is about 1.5 times lower. The annual yields of C-13 , N-15, and O-17 from nova ejection are larger than those from AGB stars. This indicates that compared to a red giant, nova eruptions are a more important source of the odd-numbered nuclear elements of C-13 , N-15, and O-17 in the Galactic interstellar medium. |
