Light curve analysis of the hybrid sdB pulsators HS0702+6043 and HS2201+2610
R. Lutz, S. Schuh, R. Silvotti +6
We present the detection of low-amplitude, long-period g-modes in two individual sdBV stars which are known to be p-mode pulsators. Only few of these hybrid objects, showing both p…
Investigation of transit-selected exoplanet candidates from the MACHO survey
S. D. Huegelmeyer, S. Dreizler, D. Homeier +1
Context: Planets outside our solar system transiting their host star, i. e. those with an orbital inclination near 90 degree, are of special interest to derive physical properties…
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…
Spectral analyses of 16 DAO white dwarfs from the Sloan Digital Sky Survey
S. D. Huegelmeyer, S. Dreizler, T. Rauch +1
We present a spectral analysis of 16 DAO white dwarfs from the Sloan Digital Sky Survey Data Release 4. With our NLTE H+He model grid, we derived photospheric parameters for these…
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…
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…
