2DStars: A two-dimensional stellar evolution code.

We introduce the 2DStars code, a new two-dimensional stellar evolution code under construction to model rotating stars. Most of our current understanding of stellar interiors and evolution is based largely on one-dimensional models. In these models, complex physical processes such as convection, rotation and magnetic fields are typically described by simplified approaches which rely on free parameters. Such parametrized descriptions have little predictive power and often fail to capture the physical nature of the underlying processes responsible for discrepancies between models and observations. Given the increasing computational power and algorithmic efficiency, multi-dimensional models are now timely and crucial in order to make progress in the field of stellar astrophysics and take full advantage of the unprecedented developments in observational astronomy, notably high-resolution spectroscopy, as well as present and future spectroscopic surveys.
