Scientific paper

Various types of evolution of accreting white dwarfs are described as a function of binary parameters (i.e., composition, mass and age of the white dwarf, its companion star, and mass accretion rate), and the conditions for the precursors of exploding or collapsing white dwarfs, and their relevance to cataclysmic variables, are discussed. Particular attention is given to helium star cataclysmics which might be the precursors of some Type I supernovae or ultrashort period X-ray binaries. Finally, new evolutionary calculations using the updated nuclear reaction rates for the formation of O+Ne+Mg white dwarfs are presented, and the composition structure and their relevance to the model for neon novae are discussed.
