Evidence for differential rotation in PG 0122+200
Successful application of inversion methods to pulsation data
Model closely reproduces observed pulsation periods
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.
