XXXIX. Orchidaceae novae et criticae

Recurrent Novae , Classical Novae , Symbiotic Novae , and Population II

Light curve analysis of decay phase of nova outburst are summarized. Nova duration is determined by the strong wind mass-loss which depends only on the white dwarf mass. Fast novae correspond very massive white dwarfs and very slow novae correspond almost lower mass limit of white dwarfs. This relation is shown in both of classical novae and recurrent novae. Light curves are theoretically repro...

Nucleosynthesis in Classical Novae

A general review of the relevance of classical novae for the chemical evolution of the Galaxy, as well as for Galactic radioactivity is presented. A special emphasis is put on the pioneering work done by Jim Truran in this field of research. The impact of recent developments in nuclear astrophysics on nova nucleosynthesis, together with the prospects for observability of novae radioactivities w...

Presolar Grains from Novae

We report the discovery of five SiC grains and one graphite grain isolated from the Murchison carbonaceous meteorite whose major-element isotopic compositions indicate an origin in nova explosions. The grains are characterized by low C/C (4-9) and N/N (5-20) ratios, large excesses in Si (Si/Si ratios range to 2.1 times solar) and high Al/Al ratios. These isotopic signatures are theoretically pr...
