| Abstract: |
This is a very brief report on an ongoing program aimed at mapping the
internal rotation profiles of stars through asteroseismology. Three
years ago, we developed and applied successfully a new technique to the
pulsating GW Vir white dwarf PG 1159–035, and were able to infer that
it rotates very slowly and rigidly over some 99% of its mass. We
applied the same approach to the three other GW Vir pulsators with
available rotational splitting data, and found similar results. We
discuss the implications of these findings on the question of the
angular momentum of white dwarfs resulting from single star evolution. |
