The Impact of Nova Outbursts on the Chemical Abundance of the Interstellar Medium
《Research in Astronomy and Astrophysics》2024年第10期116-129,共14页Guoli He Chunhua Zhu Guoliang Lü Lin Li Sufen Guo Helei Liu Jun Gao 
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...
