    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...

    Observational Evidence for a Galaxy Overdensity/Protocluster at z=6.5
    We present the results of our search near the end of the Reionization Epoch for faint galaxies around two close, massive Lyman-α emitters (LAEs) at redshift 6.5...

    Observational evidence for stellar-mass black holes
    Radial velocity studies of X-ray binaries still provide the most solid evidence for the existence of stellar-mass black holes. We currently have 20 confirmed...

    Observational Evidence for the "Hot Wall" Effect in Small Magnetic Flux Concentrations
    Introduction: When lacking polarimetric observations, the Bright Points (BPs) visible in the G-band at 430 nm are commonly used as tracers for magnetic fields...
