| 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. |
