Abstract

The knowledge of the internal rotation profile of stars is one of the key, yet
unsolved, problems of the Stellar Physics. Thanks to Helioseismology, it is possible
to invert the rotation profile of about 70\% deep into the Sun. This provides
a significant amount of information about both the seismic behaviour and the structure
of the star. We present here the basis of a new method, currently under development,
based on the use of the asymmetries of rotationally-split modes, as a
constraint to the rotation profile, and thus, to the representative models of the
studied star. As a practical case, we present the results of some test performed
on the $\beta$ Cephei star $\theta$ Ophiuchi.
