GD358: three decades of observations for the in-depth asteroseismology of a DBV star
Agnes Bischoff-Kim, J. L. Provencal, P. A. Bradley +38
We report on the analysis of 34 years of photometric observations of the pulsating helium atmosphere white dwarf GD358. The complete data set includes archival data from 1982-2006,…
Non-LTE spectral models for the gaseous debris-disk component of Ton 345
S. Hartmann, T. Nagel, T. Rauch +1
For a fraction of single white dwarfs with debris disks, an additional gaseous disk was discovered. Both dust and gas are thought to be created by the disruption of planetary bodie…
Observations and NLTE Modeling of the Gaseous Planetary Debris Disk around Ton 345
S. Hartmann, T. Nagel, T. Rauch +1
Debris disks around single white dwarfs are thought to be the remains of planetary bodies disrupted by tidal forces. Ongoing accretion of the hereby produced dust allows to detect…
Asymmetric Line Profiles in Spectra of Gaseous Metal Disks Around Single White Dwarfs
S. Hartmann, T. Nagel, T. Rauch +1
Metal-rich debris disks were discovered around several single DAZ and DBZ white dwarfs, which may stem from disruption of smaller rocky planetesimals. In some cases, the material i…
Asymmetric Line Profiles in Spectra of Gaseous Metal Disks Around Single White Dwarfs
S. Hartmann, T. Nagel, T. Rauch +1
Around several single DAZ and DBZ white dwarfs metal-rich disks have been observed, which are mostly believed to originate from disruption of smaller rocky planetesimals. In some c…
EXOTIME: searching for planets around pulsating subdwarf B stars
Sonja Schuh, Roberto Silvotti, Ronny Lutz +27
In 2007, a companion with planetary mass was found around the pulsating subdwarf B star V391 Pegasi with the timing method, indicating that a previously undiscovered population of…
