摘要:Classical novae are dramatic stellar explosions that take place in the accreted envelopes of white
dwarfs in close binary systems. These unique cataclysmic events constitute a crucible where
different scientific disciplines merge, including astrophysics, nuclear and atomic physics,
cosmochemistry, high-energy physics or computer science. In this paper, we will focus on the
nucleosynthesis accompanying such explosions. Theoretical predictions will be compared with
the elemental abundances inferred from observations of the nova ejecta as well as with the
isotopic abundance ratios measured in meteoritic grains. Special emphasis will be given to the
interplay between nova outbursts and the Galactic abundance pattern. Results from recent
simulations of nova explosions in cataclysmic primordial binaries will be also outlined. Finally,
we will stress the key role played by nuclear physics in our understanding of these explosive
phenomena by means of recent experiments and a thorough account of the impact of nuclear
uncertainties. Hints on possible key nuclear physics experiments will be given.
