The evolution of the luminosity functions in the FORS Deep Field from low to high redshift: II. The red bands
A. Gabasch, U. Hopp, G. Feulner +12
We present the redshift evolution of the restframe galaxy luminosity function (LF) in the red r', i', and z' bands as derived from the FORS Deep Field (FDF). Using the deep and hom…
Spectral analyses of DO white dwarfs and PG1159 stars from the Sloan Digital Sky Survey
S. D. Huegelmeyer, S. Dreizler, K. Werner +3
We present a model atmosphere analysis of ten new DO white dwarfs and five new PG 1159 stars discovered in the Sloan Digital Sky Survey DR1, DR2 and DR3. This is a significant incr…
Nearby star cluster formation: Probes of cosmological galaxy evolution
P. Anders, R. de Grijs, U. Fritze-v. Alvensleben
(abridged) The old Star Cluster (SC) systems surrounding any sofar investigated galaxy represent a powerful tool for the understanding of the cosmological evolution of their host g…
The Spectral Variability of Pulsating Stars: PG1159-035
T. Stahn, S. Dreizler, K. Werner
With 10m class telescopes as well as with time-tagging detectors on board of HST and FUSE, the analysis of time-resolved spectra for pulsating white dwarfs becomes feasible. We pre…
NLTE Analysis of the Ultra-short Period White-dwarf Binary RX J0806.3+1527
J. Steiper, K. Reinsch, S. Dreizler
RX J0806.3+1527 is suspected to be a double-degenerate white dwarf binary. We present first results of our NLTE analysis of its optical spectrum. The VLT/FORS1 data show a composit…
