Resumen:
Abstract. We investigate the internal rotation profile of the GW Vir (PG1159-type)star PG 0122+200 by employing an asteroseismological model that closely reproducesthe observed periods of this star. We adopt a forward approach and two inversion meth-ods based on the rotational splitting of the pulsation frequencies to explore the proper-ties of the rotation of PG 0122+200. We found evidence for differential rotation in thisstar.
