Recurrent Novae
Recurrent novae are thought to arise in the same way as classical novae, through a white dwarf in a close binary system accreting a surface layer of hydrogen from a main sequence companion.
Recurrent Nova
A recurrent nova is a which has been observed to have multiple outbursts. In the case of recurrent novae and , a shell of ejected matter can be detected spectroscopically, while exhibit no such behavior.

Recurrent Novae
These are similar to novae with a change in magnitude of 7 - 16 and a period of outburst of up to about 200 days. They show two or more outburst over recorded observations.

Recurrent novae like RS Ophiuchi (those with periods on the order of decades) are rare. Astronomers theorize however that most, if not all novae are recurrent, albeit on time scales ranging from 1,000 to 100,000 years.Seeds, Michael A.

recurrent nova - (n.)
A star known to flare up in nova outbursts more than once.
RS Ophiuchi is a recurrent nova, produced by a white dwarf and a red giant in close orbit, approximately 5,000 light-years distant.
The object, U Scorpii, is a recurrent nova that was predicted to outburst during a two-year window beginning in spring 2008.
Close on the heels of "R" is "T," a wonderful "recurrent nova" that erupted from 10th magnitude to second in 1866, then in 1946 blasted out to third, in both cases falling back to below naked-eye vision within days.
This would be referred to as a recurrent nova. I guess a recurrent nova is sort of like a repeat offender - they just can't help themselves and keep doing the same thing over and over.
Optical astronomers have also recognized 'recurrent novae' (eruptive behaviors in-between classical and dwarf novae), and 'nova-like systems'(stars that have similar spectra to other types of CVs in the visual light, but have not been seen to erupt).
RS Ophiuchi is part of a class called recurrent novae, whose brightness increase at irregular intervals by hundreds of times in a period of just a few days. It is thought to be at the brink of becoming a type-1a supernova.[2] ...
The process repeats resulting in recurrent X-ray bursts. The mechanisms that produce X-ray bursts and recurrent novae are similar. Recurrent novae form when a white dwarf accretes a surface layer of H that undergoes explosive burning.
Joy and Swings (1945) reported FeVII in one recurrent nova. The 6087 line of [FeVII] is always seen in emission in symbiotic stars. It should, however, be remarked that often one sees [FeII] and [FeVII] without the intermediate species.
RS Ophiuchi is a type of star called a recurrent nova. These strange objects stay dim for long periods of time, and then suddenly brighten. The brightest star is called Ras Alhague, and is the head of the serpent bearer.
Every 20 years or so, it gathers sufficient material to explode with enough intensity to be seen from Earth with the naked eye. The so-called recurrent nova event has now flared up six times in 108 years.
Here you will learn about simple recurrent novas and Type I supernovas. I'll show you where to find some multiple star systems, show you where some nova have been seen, and along the way you'll learn some more stars and constellations.
