Mg line profiles for cool WD and their application in the UV
Since last decade there have been great advances and extremely exciting results in the search and interpretation for cool DZ white dwarfs. In the formation of their spectra, the far wings of alkaline earth metals like ...
Improved and Tested: A New Generation of Cool White Dwarf Atmosphere Models
The photosphere of cool, helium-rich white dwarfs is notoriously tricky to model due to its fluid-like density. Using modern ab initio calculations, we have developed a new generation of atmosphere models that include ...
An Analysis of the Circumstellar Absorption of WD 1145+017
WD 1145+017 is a white dwarf that has an actively disintegrating object in orbit and also uniquely displays circumstellar gas absorption. We present a preliminary analysis of the circumstellar absorption features present ...
A New Look at Magnetic White Dwarfs
We present a homogeneous photometric analysis of a large sample of magnetic DA white dwarfs as well as selected results from a spectrophotometric analysis of magnetic carbon-dominated atmosphere white dwarfs. We find ...
