Magnetism in cool stars: observations vs models

Boris Dintrans
LATT, CNRS/Toulouse University

I will first present the last observations of large-scale magnetic fields in fully and partly-convective dwarfs thanks to spectropolarimetry. Then, the main dynamo models developed so far for these stars will be reviewed, to both those  based on mean-field approachs and direct numerical simulations of MHD. Preliminary results obtained on solar twins will be also presented and discussed.
