Abstract

A quasi-analytic study on ONeMg novae is performed to examine explosive nucleosynthesis in wide range of white dwarf and envelope masses. Comparing our results with recent observations enables us to constrain those two parameters. About a half of observed ONeMg novae may have attained high envelope masses such as ∼ 10-4 M, then obtained high burning temperatures ∼ 3-4 x 108 K. Those may have produced significant amount of 22Na. Leakage out of CNO material via alpha captures of 14,15O is not of importance in our results but initially enhanced neon in the envelope must be seed nuclei for heavy element production by the rp-process.
