NeW generAtion Dynamic ASteroseismology (NoWADAyS)

Stars that are born with convective core (massive stars, hereafter) play an important role in dynamical and chemical evolution of galaxies. Despite the importance of massive stars, their models of interior structure and evolution (ISE) remain uncalibrated with precise observations and contain many shortcomings. The NoWADAyS project exploits synergies between binarity and asteroseismology to reveal major uncertainties in the ISE models of massive stars and to provide observational feedback to the corresponding theories. Unlike the majority of astrophysical techniques that focus on the study of outermost layers of stars, asteroseismology studies stellar quakes whose properties are set by the physics inside stars. The entire lifecycle and, hence, the interior structure of a star at any moment in time are largely determined by its initial mass, which makes the mass a key parameter to measure in astrophysics. Binary stars, the two objects born together and spending their lifes as a couple, offer a unique opportunity of measuring precise stellar masses in a model-indepedent way from binary dynamics. NoWADAyS is a data-driven project that combines the strengths of the two research fields and will lead to a breakthrough in our understanding of inner workings and evolution of massive stars.
