The gaseous debris disk of the white dwarf SDSS J1228+1040. HST/COS search for far-ultraviolet signatures
S. Hartmann, T. Nagel, T. Rauch +1
Gaseous and dust debris disks around white dwarfs (WDs) are formed from tidally disrupted planetary bodies. This offers an opportunity to determine the composition of exoplanetary…
Analysis of cool DO-type white dwarfs from the Sloan Digital Sky Survey Data Release 10
N. Reindl, T. Rauch, K. Werner +3
We report on the identification of 22 new cool DO-type white dwarfs (WD) detected in Data Release 10 (DR10) of the Sloan Digital Sky Survey (SDSS). Among them, we found one more me…
The chemical composition of TS 01, the most oxygen-deficient planetary nebula. AGB nucleosynthesis in a metal-poor binary star
G. Stasinska, C. Morisset, G. Tovmassian +10
The planetary nebula TS 01 (also called PN G 135.9+55.9 or SBS 1150+599A), with its record-holding low oxygen abundance and its double degenerate close binary core (period 3.9 h),…
A Dor - An Eclipsing Subdwarf - Brown Dwarf Binary
T. Rauch
AA Dor is an eclipsing, close, post common-envelope binary (PCEB) consisting of a sdOB primary star and an unseen cool companion with an extraordinary low mass. The evolution of th…
AA Dor - An Eclipsing sdOB - Brown Dwarf Binary
Thomas Rauch
AA Dor is an eclipsing, close, post common-envelope binary consisting of a sdOB primary star and an unseen secondary with an extraordinary small mass - formally a brown dwarf. The…
HST/STIS ultraviolet spectroscopy of the supersoft X-ray source RX J0439.8-6809
A. van Teeseling, B. T. Gaensicke, K. Beuermann +3
We present ultraviolet observations of the supersoft X-ray source RXJ0439.8-6809 obtained with the Hubble Space Telescope Imaging Spectrograph. The ultraviolet spectrum is a very b…
