Accretion processes in astrophysics

WSO-UV  is a powerful tool for stellar physics, study of accretion discs and of other manifestations of activity of stars and compact objects.

Of special interest is the physics of close binaries. At a certain stage of its evolution, the mass exchange begins between the components.. Complex processes of interaction between the accretion disk and the central star determine the development of powerful stellar flares (explosions) and other energetic processes accompanied by strong UV radiation.

In the figures the examples of complex structure of gasdynamic flows in close binary stars are shown (3D models): young binary system - left figure, the polar with  complex magnetic field - right figure .
