  The evolution of a star is driven by the physical processes in its interior
making the theory of stellar structure and evolution the most crucial
ingredient for not only stellar evolution studies, but any field of astronomy
which relies on the yields along stellar evolution. High-precision time-series
photometric data assembled by recent space missions revealed that current
models of stellar structure and evolution show major shortcomings already in
the two earliest nuclear burning phases, impacting all subsequent phases prior
to the formation of the end-of-life remnant. This white paper focuses
specifically on the transport of chemical elements and of angular momentum in
the stellar structure and evolution models of stars born with convective core,
as revealed by their gravity-mode oscillations.
