On the excitation of PG1159-type pulsations.

GAUTSCHY A., ALTHAUS L.G. and SAIO H.

Abstract (from CDS):

Stability properties are presented of dipole and quadrupole nonradial oscillation modes of model stars that experienced a late helium shell flash on their way to the white-dwarf cooling domain. The computed instability domains are compared with the observed hot variable central stars of planetary nebulae and the GW Vir pulsators.
