โœฆ Synopsis

Iz quasi-analytic study on ONeMg novae is performed to examine explosive nucleosynthesis in wide range of whit,e dwarf and envelope masses.

Comparing our results n-it11 recent) observations enables us to constrain those two parameters.

-About a half of Oh served ONeMg novae may have attained high envelope masses such as N lo-' :11.,. theu obtained high burning temperatures N 3-4 x lo* Ii. Those may have produced signific~aut amount of 22Na. Leakage out of CNO material via alpha captures of 14.150 is not of import,ance in our resuhs but initially enhanced neon in the envelope must be seed nucltli for heavy element production by t,he rp-process.

Classical novae are dramatic stellar explosions with an energy release that is only overcome by supernovae and gamma-ray bursts. These unique cataclysmic events constitute a crucible where different scientific disciplines merge, including astrophysics, nuclear and atomic physics, cosmochemistry, hig
