What determines the γ-ray luminosities of classical novae?

Monthly notices of the Royal Astronomical Society
Classical novae in the Milky Way have now been well-established as high-energy GeV γ-ray sources. In novae with main-sequence companions, this emission is believed to result from shocks internal to the nova ejecta, as a later fast wind collides with an

Classical Novae

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 ...

The classical nova outburst

International Astronomical Union Colloquium, 1986
In this review I will present and discuss both the nova outburst and the theoretical calculations related to its cause and evolution. I use the commonly accepted model for a nova: a close binary system with one member a white dwarf and the other member a larger, cooler star that fills its Roche lobe.

Interacting Winds in Classical Nova Outbursts

Astrophysics and Space Science, 1995
Classical nova outbursts occur in binary systems containing a white dwarf accretor and a Roche-lobe-filling main-sequence star. The outburst is due to a thermonuclear runaway in the accreted material on the surface of the white dwarf, and results in the ejection of up to 10-4M⊙of material at velocities of several hundred to a few thousand kilometres ...

Quenched Nitrogen-included Carbonaceous Composite (QNCC): A powerful candidate of the carriers of the UIR bands in classical novae

Proceedings of the International Astronomical Union, 2019
We have succeeded in synthesizing organics, ‘Quenched Nitrogen-included Carbonaceous Composite (QNCC)’, via plasma chemical vapor deposition (CVD) method, whose infrared spectral properties reproduce the characteristics of the unidentified infrared (UIR)
