"The mass-accreting pulsating components of Algols"

I will give a review on the present status of ivestigations of attracting
group of mass-accreting pulsating components of Algols, so called oEA stars.
I will show results of recent 3-D hydrodynamic  simulations of the mass-transfer
in these systems and discuss a new methods of studies of interacting binary
systems with pulsating mass-accreting components.
