Mg line profiles for cool WD and their application in the UV
(2018-07)
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
(2018-07)
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
(2018-07)
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
(2018-07)
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 ...
