Stellar Variability: The key chart for understanding the stellar and galaxies Evolution

It has been known for centuries that stellar variability is very huge in scale. As stars evolve some pulsation on time scale ranging from second to years, other stars vary irregularly. Study of each particular type of stellar variation can shed light on the structure and life history of stars.

Stellar variability play an important role in understanding the basic physical processes and provides powerful tool to probe the stellar structure and evolution. Stellar variability are crucial for understanding the history and evolution of our local solar system, our Universe and galaxies.

Our aim to gather top scientists and discuss still open issues in modeling and try to solve discrepancies between theory and observations, concerning the physics needed to describe their structure and evolution

The meeting also will review the most recent space missions and their achievements in observations and theory.

At the end we can put some further plans that attract the young generation, and develop a strategy for the future.
