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. RNe
play an important role as one of the suspected progenitor systems of Type Ia supernovae (SNe) which are used as primary distance indicators in cosmology. Thus, it is important to investigate
the nature of central binary systems of CNe and RNe to determine the relation between the parameters of the central system and outburst type and finally ascertain the population of objects that might ultimately be candidates for Type la SNe explosions. In this talk, I will present the preliminary investigation looking for characteristics that may distinguish CNe from RNe central systems and the selection of initial targets for detailed study.
