Stars are the main form of baryon matter in the Universe. In the recent years, they are effectively studied spectroscopically and photometrically. A powerful tool for determination of fundamental stellar characteristics (temperatures, radii, gravity, chemical composition) are studies of stellar atmospheres. Also, asteroseismic investigations of stellar interiors have become possible. These characteristics give an insight into the star's evolution status, processes of its origin and further evolution, into the enrichment of the interstellar medium with products of thermonuclear synthesis under way in stellar interiors.
The advent of the new generation of large ground-based telescope, application of space-borne observing techniques, development of new methods of stellar-spectrum analysis, like those based on 3D and non-LTE modeling, opened a new era in stellar studies. In addition, observations of exoplanet transits give unprecedented new possibilities to study stellar limb darkening. The recent explosive development of observations of stellar oscillations, particularly resulting from the CoRoT and Kepler space missions, has provided completely new possibilities for using application of asteroseismic techniques to investigate the internal structure and evolution status of stars, with the potential for detailed investigations of the physics of stellar interiors. The studies of stellar variability provide information about the dynamical properties of stars. All this makes the suggested symposium "Physics of Stars" very interesting and important. We are expecting many leading researchers from different countries, engaged in various aspects of stellar physics.
The main topics to be discussed at the symposium are:
1. Observations of variable stars. Stellar pulsations. Symbiotic stars. Cataclysmic variables. Supernovae. Binary stars.
2. Physical processes in binary stars.
3. Spectroscopic, photometric, and polarimetric observations of stationary stars.
4. Modern status of stellar atmosphere and line formation modelling including convective time-dependent inhomogeneity of stellar atmospheres and departures from LTE.
5. Interpretation of stellar observations. Accuracy of the derived stellar parameters.
