    Periodic mass-loss episodes due to an oscillation mode with variable amplitude in the hot supergiant HD 50064
    Aims: We aim to interpret the photometric and spectroscopic variability of the luminous blue variable supergiant HD 50064 (V = 8.21). Methods: CoRoT space...

    Photometric detection of internal gravity waves in upper main-sequence stars. I. Methodology and application to CoRoT targets
    Context. Main sequence stars with a convective core are predicted to stochastically excite internal gravity waves (IGWs), which effectively transport angular...
