DESCRIPTION:Solar evolutionary models are key calibrators of stellar evolut
 ion theory. The high quality of observational constraints and the fact that
  the solar mass\, radius and age are known with high accuracy and precision
  allows to use the Sun as a true laboratory of fundamental physics. Over th
 e last decades\, most solar modellers relied on a simplified framework to m
 odel the evolution of the Sun\, called the Standard Solar Model framework\,
  neglecting dynamical processes and designed for large-scale computations. 
 These models encountered widespread success (see e.g. Model S from Christen
 sen-Dalsgaard et al. 1996)\, but both helioseismic and asteroseismic data h
 ave shown the limitations of standard models. In the last months of the pre
 paration of the PLATO mission (to be launched in early 2027)\, the accuracy
  of stellar models comes as a crucial question that actually links all our 
 recent progress in asteroseismology back to one burning question: how well 
 do we know our Sun? To arrange a visit with the speaker during the visit\,
