To determine the mass and size of planets found around other stars or to date stellar populations in order to limit the number of cosmological models, among other things, it is essential know what goes on inside a star. The only gateway we have to that stellar interior is the study of stellar oscillations, or asteroseismology. Now, for the first time, a study led by researchers from the Institute of Astrophysics of Andalusia (IAA-CSIC) has shown the validity of this tool for the study of stars that are hotter and more massive than the sun.
