The awakening of a classical nova from hibernation [PDF]
Nature, 2016 Cataclysmic variable stars (CVs) are close binary systems consisting of a white dwarf (primary) that is accreting matter from a low-mass companion star (secondary). From time to time such systems undergo large-amplitude brightenings. The most spectacular eruptions, over $10^4$ times in brightness, occur in classical novae and are caused by a ...

Numerical modelling of the classical nova outburst [PDF]
International Astronomical Union Colloquium, 1988 AbstractWe describe a mechanism that promises to explain how classical nova outbursts take place on white dwarfs of 1 M⊙ or less and for accretion rates of 4 × 10−10 M⊙ yr−1 or greater.

Suppression of Shock X-Ray Emission in Novae from Turbulent Mixing with Cool Gas
The Astrophysical JournalShock interaction in classical novae occurs when a fast outflow from the white dwarf ≳1000 km s ^−1 collides with a slower, cooler shell of gas released earlier in the outburst.

Spectra of V1405 Cas at the Very Beginning Indicate a Low-mass ONeMg White Dwarf Progenitor
The Astrophysical Journal, 2023 The lowest possible mass of ONeMg white dwarfs (WDs) has not been clarified despite its importance in the formation and evolution of WDs. We tackle this issue by studying the properties of V1405 Cas (Nova Cassiopeiae 2021), which is an outlier given a ...

Recurrent Nova V2487 Oph Had Superflares in 1941 and 1942 with Radiant Energies of 1042.5±1.6 erg
The Astrophysical JournalV2487 Ophiuchi (V2487 Oph) is a recurrent nova with classical nova eruptions in 1900 and 1998, and it is also the most extreme known superflare star. These superflares are roughly hour-long flares with amplitudes and optical energies reaching up to 1.10 ...

Outstanding problems in nuclear astrophysics: recent progress at TRIUMF
AIP Advances, 2014 Recent experimental and theoretical efforts at TRIUMF on nuclear reactions relevant to big bang nucleosynthesis, quiescent stellar fusion, classical novae, and Type I X-ray bursts are described.

The Astrophysical JournalRecurrent nova U Scorpii (U Sco) is one of the prototypes for a Type Ia supernova progenitor. The logic is that the white dwarf is near the Chandrasekhar mass and gas is accumulating onto its surface at a near-maximal accretion rate, so it will soon ...

Ultraviolet observations of classical novae in outburst [PDF]
International Astronomical Union Colloquium, 1990 More than a dozen classical novae in outburst have been observed with the International Ultraviolet Explorer since its launch in 1978. These data represent a crucial breakthrough in understanding several aspects of the classical novae phenomenon including nucleosynthesis, the energetics of the explosion, the dynamics of the mass ejection, and the ...
