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