Classical Novae Masquerading as Dwarf Novae? Outburst Properties of Cataclysmic Variables with ASAS-SN [PDF]
Astrophysical Journal, 2021 The unprecedented sky coverage and observing cadence of the All-Sky Automated Survey for SuperNovae (ASAS-SN) has resulted in the discovery and continued monitoring of a large sample of Galactic transients.

New Insights into Classical Novae [PDF]
Annual Review of Astronomy and Astrophysics, 2020 We survey our understanding of classical novae—nonterminal, thermonuclear eruptions on the surfaces of white dwarfs in binary systems. The recent and unexpected discovery of GeV gamma rays from Galactic novae has highlighted the complexity of novae and ...

Gamma-Ray Light Curves and Spectra of Classical Novae [PDF]
Monthly notices of the Royal Astronomical Society, 2021 The nucleosynthesis in classical novae, in particular that of radioactive isotopes, is directly measurable by its γ-ray signature. Despite decades of observations, MeV γ-rays from novae have never been detected – neither individually at the time of the

Explaining Prolonged Fluctuations in Light Curves of Classical Novae via Modeling [PDF]
Monthly notices of the Royal Astronomical Society, 2022 Fluctuations during a prolonged maximum have been observed in several nova eruptions, although it is not clear, and can not be deduced directly from observations, if the phenomenon is an actual physical reaction to some mechanism originating in the ...

The onset of jets in classical novae [PDF]
Monthly notices of the Royal Astronomical Society, 2021 We present two further classical novae, V906 Car and V5668 Sgr, which show jets and accretion disc spectral signatures in their H α complexes throughout the first 1000 d following their eruptions.

Discovery of 13 New Orbital Periods for Classical Novae [PDF]
, 2021 I report new orbital periods (P) for 13 classical novae, based on light curves from TESS, AAVSO, and other public archives. These new nova periods now constitute nearly one-seventh of all known nova periods.

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 ...

Uncertainties in the 18F(p,alpha)15O reaction rate in classical novae [PDF]
, 2021 Context. Direct observation of γ-ray emission from the decay of F ejected in classical nova outbursts remains a major focus of the nuclear astrophysics community. However, modeling the abundance of ejected F, and thus the predicted detectability distance
