Query: Rotational mixing in low-mass stars : I Effect of the mu-gradients in
  main sequence and subgiant Pop I stars   We present a first set of results concerning stellar evolution of rotating
low-mass stars. Our models include fully consistent transport of angular
momentum and chemicals due to the combined action of rotation induced mixing
(according to Maeder & Zahn 1998) and element segregation. The analysis of the
effects of local variations of molecular weight due to the meridional
circulation on the transport of angular momentum and chemicals are under the
scope of this study. We apply this mechanism to low mass main sequence and
subgiant stars of population I. We show that the so-called $\mu$-currents are
of major importance in setting the shape of the rotation profile, specially
near the core. Furthermore, as shown by Talon & Charbonnel (1998) and
Charbonnel & Talon (1999) using models without $\mu$-currents, we confirm that
rotation-induced mixing in stars braked via magnetic torquing can explain the
blue side of the Li dip, as well as the low Li abundances observed in subgiants
even when $\mu$-currents are taken into account. We emphasize that $\mu$
variations are not to be neglected when treating rotation-induced mixing, and
that they could be of great importance for latter evolutionary stages.
