Observational constraints on the evolutionary connection between PG 1159 stars and DO white dwarfs
S. D. Huegelmeyer, S. Dreizler, K. Werner +3
The Sloan Digital Sky Survey has provided spectra of a large number of new PG 1159 stars and DO white dwarfs. This increase in known hot H-deficient compact objects significantly i…
Hot DB White Dwarfs from the Sloan Digital Sky Survey
Daniel J. Eisenstein, James Liebert, Detlev Koester +12
We present ugriz photometry and optical spectroscopy for 28 DB and DO white dwarfs with temperatures between 28,000K and 45,000K. About 10 of these are particularly well-observed;…
Spectral analyses of eighteen hot H-deficient (pre-) white dwarfs from the Sloan Digital Sky Survey Data Release 4
S. D. Huegelmeyer, S. Dreizler, D. Homeier +4
Context: The Sloan Digital Sky Survey Data Release 4 has provided spectra of several new PG 1159 stars and DO white dwarfs. This increase in known hot H-deficient compact objects s…
