The Progenitor Systems of Classical Novae in M31 [PDF]
The Astrophysical JournalWe present the first characterization of the statistical relationship between a large sample of novae in M31 and their progenitor stellar populations in the form of a delay time distribution.

Classical Novae at Radio Wavelengths [PDF]
The Astrophysical Journal Supplement Series, 2021 Abstract We present radio observations (1–40 GHz) for 36 classical novae, representing data from over five decades compiled from the literature, telescope archives, and our own programs. Our targets display a striking diversity in their optical parameters (e.g., spanning optical fading timescales, t 2 = 1–263 days), and

Nucleosynthesis in classical novae [PDF]
Nuclear Physics A, 2001 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 ...

, 2008 This second edition has been updated and revised and contains contributions covering important developments in this field, and reflecting on interesting insights into classical novae. The book examines thermonuclear processes, the evolution of nova systems, nova atmospheres and winds, the evolution of dust and molecules in novae, nova remnants and ...

Search for 22Na in novae supported by a novel method for measuring femtosecond nuclear lifetimes [PDF]
Nature Communications, 2023 Classical novae are thermonuclear explosions in stellar binary systems, and important sources of 26Al and 22Na. While γ rays from the decay of the former radioisotope have been observed throughout the Galaxy, 22Na remains untraceable.

The Recurrent Novae and Their Relation with Classical Novae
AIP Conference Proceedings, 2002 Recurrent novae (RNe) are a subclass of cataclysmic variables classified based on recorded observations of more than one nova outburst. They form a small, but heterogeneous group of objects, with 10 known members, that undergo classical nova‐like outbursts, with the significant differences being in the amplitude and the frequency of the outbursts.

Classical novae with CUBES [PDF]
Experimental Astronomy, 2022 Among the main science cases that have motivated the proposal of CUBES, a new high-resolution spectrograph for the Very Large Telescope at the European Southern Observatory, there is the study and the characterisation of the nucleosynthesis of beryllium.

The UBV Color Evolution of Classical and Symbiotic Novae [PDF]
Acta Polytechnica CTU Proceedings, 2015 We identified a general course of classical nova outbursts in the B − V vs. U − B diagram. It has been reported that novae show spectra similar to A–F supergiants near optical light maximum.

NUCLEAR MIXING METERS FOR CLASSICAL NOVAE [PDF]
The Astrophysical Journal, 2013 Classical novae are caused by mass transfer episodes from a main sequence star onto a white dwarf via Roche lobe overflow. This material forms an accretion disk around the white dwarf. Ultimately, a fraction of this material spirals in and piles up on the white dwarf surface under electron-degenerate conditions. The subsequently occurring thermonuclear
