    The Impact of a Fossil Magnetic Field on Dipolar Mixed-Mode Frequencies in Sub- and Red-Giant Stars

    The recent discovery of low-amplitude dipolar oscillation mixed modes in massive red giants indicates the presence of a missing physical process inside their cores. Stars more massive than ∼ 1.3 M⊙ are known to d...

    Tides and angular momentum redistribution inside low-mass stars hosting planets: a first dynamical model

    We introduce a general mathematical framework to model the internal transport of angular momentum in a star hosting a close-in planetary/stellar companion. By assuming that the tidal and rotational distortions...

    The PLATO 2.0 mission

    PLATO 2.0 has recently been selected for ESA’s M3 launch opportunity (2022/24). Providing accurate key planet parameters (radius, mass, density and age) in statistical numbers, it addresses fundamental questio...

    Interior and Exterior Clues of Solar Activity

    Two research paths are described to obtain better understanding of the origin of global solar activity. First, observations with a multichannel resonant spectrometer may reveal the dynamics of the solar core, ...

    DynaMICCS: The Sun as an Integrated Magnetic System

    After the observations of SoHO, there is a real need to pursue global solar observations from the core to the corona and to put new constraints on the dynamical processes which act inside and outside the Sun. ...

    Angular Momentum Transport in the Sun’s Radiative Zone by Gravito-Inertial Waves

    Internal gravity waves constitute an efficient process for angular momentum transport over large distances. They are now seen as an important ingredient in understanding the evolution of stellar rotation and c...
