Discovery of photospheric CaX emission lines in the far-UV spectrum of the hottest known white dwarf (KPD0005+5106)
K. Werner, T. Rauch, J. W. Kruk
For the first time, we have identified photospheric emission lines in the far-UV spectrum of a white dwarf. They were discovered in the Far Ultraviolet Spectroscopic Explorer spect…
Project Lyman
Stephan R. McCandliss, Jeffrey W. Kruk, William P. Blair +20
We explore the design of a space mission, Project Lyman, which has the goal of quantifying the ionization history of the universe from the present epoch to a redshift of z ~ 3. Obs…
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…
