The Recurrent Novae and Their Relation with Classical Novae

AIP Conference Proceedings, 2002
Recurrent novae (RNe) are a subclass of cataclysmic variables classified based on recorded observations of more than one nova outburst. They form a small, but heterogeneous group of objects, with 10 known members, that undergo classical nova‐like outbursts, with the significant differences being in the amplitude and the frequency of the outbursts.

A Recurrent Nova

Nature, 1946
ON-February 10 the variable star T Coronae Borealis, normally of magnitude 9, was seen to have blazed up to magnitude 3. This star had a typical nova outburst in 1866, when it was the first nova to be examined spectroscopically. Unlike other novae, its spectrum after fading was of late type with strong absorption bands of titanium oxide.

The Evolutionary Significance of Recurrent Novae

International Astronomical Union Colloquium, 1979
Within the past few years, it has become increasingly apparent that common novae and dwarf novae must owe their origin to binary systems of much larger initial separation than they now have (Paczynski 1976; Ritter 1975, 1976; Webbink 1975). This was demanded by the realization that the white dwarfs in these binaries are generally quite massive (see for

Studies of Classical and Recurrent Novae

Publications of the Astronomical Society of the Pacific, 1992
Novae belong to the cataclysmic-variable class of objects. These objects are interacting binary star systems consisting of a Roche-lobe filling secondary, on or near the main sequence, losing hydrogen-rich material through the inner-Lagrangian point onto an accretion disk that surrounds the primary, which, in most cases, is a white dwarf.
