摘要: Abstract Based on observations obtained with the 2.5m Isaac Newton Telescope we show that characteristics of SW Sex stars can be explained by dominance a `hot-spot' like feature in accretion disk. In this region is located at distance 0.5RL1 from white-dwarf and best visible phase ϕ=0.95. The location hot-spot as deduced spectral eclipse mapping coincides formation site main emission lines. We deduce formed shock, which speculate to consequence high mass-transfer rate long spin-period non-magnetic white dwarf.
