Scientific Research

Current research interests:

Close binaries:

• Accretion onto white dwarfs, spectra
• Outbursts of dwarf novae and X-ray transient sources
• Supersoft X-ray sources

Accretion modes:

• Disk accretion or advection-dominated flow (ADAF)
• Change of the accretion mode = spectral transitions in X-ray binaries
• Evaporation of the inner accretion disk, disk truncation
• Hysteresis in lightcurves of X-ray binaries
• Re-condensation of gas from the ADF to an inner disk
