SOUL: Stellar evOlution in fUll gLory: rotation, magnetism, oscillations, outflows, tides, and binarity

The long-term Methusalem project SOUL is situated in the field of astrophysics. Its global aim is the development of novel three-dimensional (3D) models for close binary and star-planet systems. We will develop computational tools to simulate the evolution of such systems, from birth to death. Our 3D evolutionary models will be unique in that they will maintain consistency between the physical and chemical ingredients of the stellar interiors, atmospheres, and outflows. Additionally, our models will have asteroseismically calibrated rotation and magnetic field profiles inside the stars, while also considering tidal interactions between the two components. The outflows and mass and angular momentum exchange of the models will meet observations of the highest precision. Our open-source SOUL deliverables will have major impact for the whole of astrophysics, including gravitational wave physics and exoplanet research.
