Abstract: Outburst in two classes of interacting binary systems, the symbiotic stars (SSs) and the cataclysmic variables (CVs), show a number of similarities in spite of their very different orbital periods. Typical periods for SSs are of the order of years, whereas for CVs they are only a few hours. Both systems undergo unpredictable outbursts characterized by brightening in the optical by 1–3 mag and 7–15 mag for SSs and CVs, respectively. By modeling the multiwavelength SED of selected examples from both groups of interacting binaries, I determine their basic physical parameters at a given time during the outburst evolution. In this way I show that the principal difference between outbursts of these objects is their energy, whereas the ionization structure of their ejecta is quite similar. This suggests that the mechanism for mass ejection by the white dwarfs in these systems is also similar.
