Classical novae: Properties between outbursts [PDF]

open access: yesInternational Astronomical Union Colloquium, 1990
With the recent publication of Classical Novae, edited by Bode and Evans, there is no need for me to give a list of novae or their overall characteristics. Furthermore, probably the most interesting developments in the past few years in studies of novae during quiescence have been in those areas (magnetic systems, long term brightness variations) which

Classical Novae Masquerading as Dwarf Novae? Outburst Properties of Cataclysmic Variables with ASAS-SN

open access: yes, 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.

Evolutionary Period Changes for 52 Cataclysmic Variables, and the Failure for the Most-fundamental Prediction of the Magnetic Braking Model

open access: yesThe Astrophysical Journal
The evolution of cataclysmic variables (CVs) is driven by period changes ( $\dot{P}$ ), for which the long-venerable consensus is the magnetic braking model (MBM).

Gamma Rays from Classical Novae [PDF]

open access: yes, 1997
NASA at the University of Chicago, provided support for a program of theoretical research into the nature of the thermonuclear outbursts of the classical novae and their implications for gamma ray astronomy.

The 30P(p, γ)31S reaction in classical novae: progress and prospects

open access: yesAIP Advances, 2014
The unknown thermonuclear rate of the 30P(p, γ)31S reaction at classical-nova temperatures currently prohibits the accurate modeling of nova nucleosynthesis in the A ⩾ 30 region.

Fermi-LAT gamma-ray detections of classical novae V1369 Centauri 2013 and V5668 Sagittarii 2015

open access: yes, 2016
We report the Fermi Large Area Telescope (LAT) detections of high-energy (>100 MeV) γ-ray emission from two recent optically bright classical novae, V1369 Centauri 2013 and V5668 Sagittarii 2015.

Optical studies of classical novae in outburst [PDF]

open access: yesInternational Astronomical Union Colloquium, 1990
AbstractA nova is followed optically from preoutburst to postoutburst appearance. Photospheric and atmospheric observational data are explained qualitatively through the energy budget, apparent in super-Eddington, Eddington, and sub-Eddington states, and the particle fluxes, according to their role in Grotrian’s model.

Classical Novae – Before and After Outburst [PDF]

open access: yesInternational Astronomical Union Colloquium, 1988
Classical nova (CN) and dwarf nova (DN) systems have the same binary components (a low-mass main sequence star and a white dwarf) and the same orbital periods. An important question that therefore arises is: are these systems really different ? (and if so, what is the fundamental difference ?) or, are these the same systems, metamorphosing from one ...
