A superoutburst of the dwarf nova EK Trianguli Austalis

Description

Simultaneous UV and optical spectrophotometry were obtained during several stages of a superoutburst of EK TrA. The observed spectra are compared with steady disc models, built both of blackbodies or Kurucz stellar atmospheres and with optically thin contributions. Atmosphere models predict much lower mass transfer rates than blackbody models. Assuming a quasi-steady disc, the size of the optically thick portion decreases between the peak and decline of the superoutburst. (author)
