Generalized theory of shell flash and accreting white dwarfs
Abstract
Theories of shell flash are summarized and generalized from in order to attain a nonlinear, yet almost analytical, theory which treats the development of shell flash in finite amplitude. Recurrence of shell flashes is shown to be well understood as a nonlinear oscillation in a dissipative system which tends to be a limiting cycle. As a result, the strength of the peak energy generation and the recurrence time of the shell flashes are found to be related to the mass of accreting white dwarfs and the accretion rate.
