Probing the internal rotation of pre-white dwarf stars with asteroseismology: the case of PG 0122+200
(Royal Astronomical Society, 2011-12)
We put asteroseismological constraints on the internal rotation profile of the GW Vir (PG1159-type) star PG 0122+200. To this end we employ a state-of-the-art asteroseismological model for this star and assess the expected ...
The period and amplitude changes in the coolest GW Virginis variable star (PG 1159-type) PG 0122+200
(Edp Sciences, 2011-04)
Context. The PG 1159 pre-white dwarf stars experiment a rapidly cooling phase with a time scale of a few 106 years. Theoretical models predict that the neutrinos produced in their core should play a dominant role in the ...
