The Rise of Nova V1674 Herculis

The Astrophysical Journal
Observational constraints on classical novae are heavily biased to phases near optical peak and later because of the simple fact that novae are not typically discovered until they become bright. The earliest phases of brightening, coming before discovery,

The EUVE Observations of Dwarf Novae [PDF]

International Astronomical Union Colloquium, 1996
In the standard theory of dwarf novae in outburst, the boundary layer region between the inner edge of the accretion disk and the white dwarf surface radiates primarily in the extreme ultraviolet. Using EUVE, observers have been able to obtain spectra with sufficient spectral resolution to characterize accurately the emission from several dwarf novae ...

Recent progress in understanding the eruptions of classical novae [PDF]

Dramatic progress has occurred in the last two decades in understanding the physical processes and events leading up to, and transpiring during the eruption of a classical nova.

Dwarf nova oscillations and quasi-periodic oscillations in cataclysmic variables -- VI. Spin rates, propellering, and coherence

, 2007
We examine published observations of dwarf nova oscillations (DNOs) on the rise and decline of outbursts and show that their rates of change are in reasonable agreement with those predicted from the magnetic accretion model.

Nova Outbursts on Rotating Oblate White Dwarfs [PDF]

International Astronomical Union Colloquium, 1996
Observations of spatially resolved nova shells and reconstructions from emission line profiles show that a ring/blob asymmetry in the ejecta of novae is very common (Martin 1989). The polar blobs expand more rapidly than the equatorial rings, giving the ejecta an overall prolate geometry.Observations of the formation of carbonaceous and silicate dusts ...

Dwarf Novae in the Shortest Orbital Period Regime: I. A New Short Period Dwarf Nova, OT J055717+683226

, 2009
We report the observation of a new dwarf nova, OT J055717+683226, during its first-ever recorded superoutburst in December 2006. Our observation shows that this object is an SU UMa-type dwarf nova having a very short superhump period of 76.67+/- 0.03 min

Fully Self-consistent Nova Explosion Models Reproducing Light Curves of KT Eri, V339 Del, V597 Pup, and SMC NOVA 2016-10a

The Astrophysical Journal
The rising phase toward the optical maximum of a classical nova is one of the last frontiers of nova study. Constructing free–free emission model light curves based on our fully self-consistent nova explosion models, we present several theoretical light ...
