    Testing stellar evolutionary theory with asteroseismology and/in binary stars
    The theory of stellar evolution is well developed over the past decades, and in particular the predictions of one dimensional numerical models have passed basic...

    The age decay of stellar magnetic activity in MS field solar-type stars
    The age decay of two indicators of the stellar magnetic activity (λ2800 Mg II emission flux and λ10830 He I equivalent width) have been studied for field solar...

    The Carbon Star DY Persei May Be a Cool R Coronae Borealis Variable
    Optical and near-IR photometry suggests that the carbon star DY Persei exhibits fadings similar to those of R Coronae Borealis (RCB) variables. Photometric...

    The complex Milky Way history
    In this seminar I will focus on how the avalanche of new data changes our views on how our Galaxy formed and evolved. Precise astrometric, spectroscopic...

    The early nucleosynthesis of O and Fe
    The new observational O/Fe vs Fe/H relationship in halo dwarfs is analyzed in terms of a model of chemical evolution for the solar neighborhood. The role of...

    The evolution of a supernova remnant in a strongly magnetized interstellar medium
    Several aspects of the evolution of an SNR into a low-beta ISM are investigated. The presence of a strong magnetic field in the unperturbed ISM is found to have...
