The lectures presented deal with theories on the very early universe, capable of providing the initial conditions of the Friedmann model and of generating...
Observational Constraints on Nucleosynthesis in AGB Stars
AGB stars, in particular those of carbon types, are excellent laboratories to constraint the theory of stellar structure, evolution and nucleosynthesis. Despite...
Observational constraints on s-process nucleosynthesis in massive galactic O-rich AGB stars.
Using high resolution optical spectroscopy (R˜40,000-50,000) we have derived the Li and Zr abundances of a large sample of galactic O-rich AGB stars. Our...
Observational Cosmology: caveats and open questions in the standard model
I will review some results of observational cosmology which critically cast doubt upon the foundations of the standard cosmology: 1) The redshifts of the...
