On Possible Oxygen/Neon White Dwarfs: H1504+65 and the White Dwarf Donors in Ultracompact X-ray Binaries
K. Werner, N. J. Hammer, T. Nagel +2
We discuss the possibility to detect O/Ne white dwarfs by evidence for Ne overabundances. The hottest known WD, H1504+65, could be the only single WD for which we might be able to…
Modeling of Oxygen-Neon Dominated Accretion Disks in Ultracompact X-ray Binaries: 4U1626-67
K. Werner, T. Nagel, S. Dreizler +1
We report on first results of computing synthetic spectra from H/He-poor accretion disks in ultracompact LMXBs. We aim at the determination of the chemical composition of the very…
Model Photospheres with Accelerated Lambda Iteration
K. Werner, J. L. Deetjen, S. Dreizler +3
We address the classical stellar-atmosphere problem and describe our method of numerical solution in detail. The problem consists of the solution of the radiation transfer equation…
Stellar Atmosphere and Accretion Disk Models for the Hot Component in Symbiotic Stars
K. Werner, J. L. Deetjen, S. Dreizler +2
We describe our NLTE codes which allow the computation of synthetic spectra of hot stars and accretion disks. They can be combined to compute ionizing fluxes from the hot component…
