Angular momentum transport in stellar interiors
Stars lose a significant amount of angular momentum between birth and death, implying that
efficient processes transporting it from the core to the surface are active. Space …

Internal mixing of rotating stars inferred from dipole gravity modes
During most of their life, stars fuse hydrogen into helium in their cores. The mixing of
chemical elements in the radiative envelope of stars with a convective core is able to …
