UV and FUV spectroscopy of the hybrid PG 1159-type central star NGC 7094
M. Ziegler, T. Rauch, E. Reiff +3
Previous studies aiming at the iron-abundance determination in three PG 1159 stars (K 1-16, PG 1159-035, NGC 7094) and a [WC]-PG 1159 transition star (Abell 78) have revealed that…
Search For Iron, Nickel, and Fluorine in PG1159 Stars
E. Reiff, T. Rauch, K. Werner +2
A possible origin of the iron-deficiency in PG1159 stars could be neutron captures on Fe nuclei. A nickel overabundance would corroborate this idea. Consequently we are looking for…
A new period determination for the close PG1159 binary SDSSJ212531.92-010745.9
S. Schuh, I. Traulsen, T. Nagel +6
Methods to measure masses of PG1159 stars in order to test evolutionary scenarios are currently based on spectroscopic masses or asteroseismological mass determinations. One recent…
Elemental Abundances in PG1159 Stars
K. Werner, T. Rauch, E. Reiff +1
The hydrogen-deficiency in extremely hot post-AGB stars of spectral class PG1159 is probably caused by a (very) late helium-shell flash or a AGB final thermal pulse that consumes t…
High-resolution ultraviolet spectroscopy of PG1159-035 with HST and FUSE
D. Jahn, T. Rauch, E. Reiff +3
PG1159-035 is the prototype of the PG1159 spectral class which consists of extremely hot hydrogen-deficient (pre-) white dwarfs. It is also the prototype of the GW Vir variables, w…
AGB star intershell abundances inferred from analyses of extremely hot H-deficient post-AGB stars
K. Werner, D. Jahn, T. Rauch +3
The hydrogen-deficiency in extremely hot post-AGB stars of spectral class PG1159 is probably caused by a (very) late helium-shell flash or a AGB final thermal pulse that consumes t…
