| Abstract: |
We review some important pending physical problems in stellar evolution and emphasize the role played by asterosesimic investigations in shedding some light on these open questions. We successively discuss the amount of extra-mixing in core nuclear burning stars, the structure of Red Giant Branch and Red Clump stars with a special emphasis on their close link to the chemical evolution of our Galaxy, some suspected uncertainties in opacities in massive stars, the mass-loss rates in massive stars and the presence of intermediate convection zones in supergiants. We show that asteroseismology represents an important tool which, added to the other tools which are photometry, spectroscopy and interferometry, helps us draw a more precise and realistic picture of the structure and evolution of stars. |
