    Seminars

    GRD seminars happen every Thursday at 1:30pm CET.
    They are about 30mn talks, followed by an open discussion.
    Topics of the talks are mostly (but not only) related to the main research themes of the team.

    Yaël Nazé – The mysterious gamma Cas stars

    Amphi du LAM

    Long thought to be a prototype of Be stars, the first detected case of such objects, gamma Cas, was found to be actually atypical amongst them! Indeed, it emits very […]
