Macroscopic Treatment of Radio Emission from Cosmic Ray Air Showers based on Shower Simulations
Klaus Werner, Olaf Scholten
We present a macroscopic calculation of coherent electro-magnetic radiation from air showers initiated by ultra-high energy cosmic rays, based on currents obtained from Monte Carlo…
HIRDES - The High-Resolution Double-Echelle Spectrograph for the World Space Observatory Ultraviolet (WSO/UV)
K. Werner, J. Barnstedt, W. Gringel +10
The World Space Observatory Ultraviolet (WSO/UV) is a multi-national project grown out of the needs of the astronomical community to have future access to the UV range. WSO/UV cons…
KPD0005+5106: Hottest DO White Dwarf Much Hotter Than Assumed
K. Werner, T. Rauch, J. W. Kruk
KPD0005+5106 is the hottest known helium-rich white dwarf. We have identified NeVIII lines in UV and optical spectra and conclude that it is significantly hotter than previously th…
Elemental Abundances in PG1159 Stars
K. Werner, T. Rauch, E. Reiff +1
The hydrogen-deficiency in extremely hot post-AGB stars of spectral class PG1159 is probably caused by a (very) late helium-shell flash or a AGB final thermal pulse that consumes t…
FUV Spectroscopy of the sdOB Primary of the Eclipsing Binary System AA Dor
Johannes Fleig, Thomas Rauch, Klaus Werner +1
AA Dor is an eclipsing, close, post common-envelope binary (PCEB). We present a detailed spectral analysis of its sdOB primary star based on observations obtained with the Far Ultr…
A Macroscopic Description of Coherent Geo-Magnetic Radiation from Cosmic Ray Air Showers
O. Scholten, K. Werner, F. Rusydi
We have developed a macroscopic description of coherent electro-magnetic radiation from air showers initiated by ultra-high energy cosmic rays due to the presence of the geo-magnet…
