Recurrent novae (RNe) are novae with multiple recorded outbursts powered by a thermonuclear runaway. This on the surface of the white dwarf in a close binary system in which a late type main-sequence or giant secondary star is filling its Roche lobe and play and transferring material onto the white dwarf. They resemble classical novae (CNe) outburst in severakaspects and by definition ; certain of CNe will join the class of RNe when a second major outburst is recorded.
