Stellar evolution beyond the standard picture

Stellar evolution is a core discipline of modern astrophysics. It produces models used to study stars as physical objects, but also to characterize exoplanets or study the formation and evolution of galaxies and stellar associations.

Standard stellar evolution models are fully operational since the 1950's, and have been very successful despite strong assumptions as for instance spherical symmetry, absence of magnetic fields, rotation and any non-convective transport processes. These standard models allow a zero order understanding of stellar structure and evolution, but they are challenged by an increasing number of observational evidences, which has motivated the development of non-standard stellar evolution models in the past 20 years or so.

In this talk, I will review our current understanding of stellar evolution beyond the standard picture, and I will present the recent evolutions as well as those to be prepared in the light of the most recent observational constraints.
