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...
متن کاملCNO ”Breakout” and Nucleosynthesis in Classical Novae
For very slow white dwarf accretors in CV’s Townsley and Bildsten (2004) found a relation between the accretion rate Ṁ and the central temperature of the white dwarf Tc. According to this relation for Ṁ less than 10 −10M⊙yr −1 Tc is much lower than 10 K. Motivated by this study we follow the thermonuclear runaway on massive white dwarfs (MWD = 1.25 − 1.40 M⊙) with Tc lower than 10 K, accreting ...
متن کاملNucleosynthesis in Classical Novae : CO vs ONe white dwarfs
Detailed nucleosynthesis in the ejecta of classical novae has been determined for a grid of hydrodynamic nova models. The reported 14 evolutionary sequences, followed from the onset of accretion up to the explosion and ejection stages, span a range of CO and ONe white dwarf masses (0.8–1.35 M⊙) and mixing levels between the accreted envelope and the underlying white dwarf core (25–75%). The syn...
متن کاملNuclear Ashes: Reviewing Thirty Years of Nucleosynthesis in Classical Novae
One of the observational evidences in support of the thermonuclear runaway model for the classical nova outburst relies on the accompanying nucleosynthesis. In this paper, we stress the relevant role played by nucleosynthesis in our understanding of the nova phenomenon by constraining models through a comparison with both the atomic abundance determinations from the ejecta and the isotopic rati...
متن کاملRecurrent 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...
