    The Magnetic Nature of Our Sun
    This talk will give an overview of our understanding of the Sun in the 1960's, the major discoveries since then, and the main questions that need to be answered...

    The phase function for stellar acoustic oscillations. I - Theory
    The influence of the upper layers of a star on p-mode frequencies can be described asymptotically by means of a phase function, which depends essentially only...

    The phase function for stellar acoustic oscillations. II - Effects of filtering
    Frequencies of solar acoustic oscillations can be analyzed asymptotically in terms of a function determined by the sound speed in the bulk of the sun and a...

    Towards Long-Term Solar Irradiance Modelling: Network Contrasts from Magneto-Convection Simulations
    Solar irradiance changes on a wide range of time scales and is a key driver of the Earth's climate where secular variability in particular is relevant. This is...
