Abstract: Seismology of stars provides insight into the physical mechanisms takingplace in their interior, with modes of oscillation probing different layers.Low-amplitude acoustic oscillations excited by turbulent convection weredetected four decades ago in the Sun and more recently in low-massmain-sequence stars. Using data gathered by the Convection Rotation andPlanetary Transits mission, we report here on the detection of solar-likeoscillations in a massive star, V1449 Aql, which is a known large-amplitude bCephei pulsator.
