The PNN and PG 1159 connection.
KAWALER S.D.
Abstract (from CDS):
WET observations of PG 1159 and PG 2131 have given us detailed data on these stars, which are presumed to be the descendants of planetary nebula central stars and the ancestors of ordinary white dwarfs. Networked observations of the pulsating central stars by WET and by Howard Bond's collaboration are puzzling, but may provide closure in the modeling of the late stages of normal stellar evolution.
