Importance of Compton scattering to radiation spectra of isolated neutron stars
V. Suleimanov, K. Werner
Model atmospheres of isolated neutron stars with low magnetic field are calculated with Compton scattering taking into account. Models with effective temperatures 1, 3 and 5 MK, wi…
Non-LTE Models for Neutron Star Atmospheres and Supernova-Fallback Disks
K. Werner, T. Nagel, T. Rauch +1
We describe our recent progress in modeling supernova-fallback disks and neutron star (NS) atmospheres. We present a first detailed spectrum synthesis calculation of a SN-fallback…
New facts about muon production in Extended Air Shower simulations
T. Pierog, K. Werner
Whereas air shower simulations are very valuable tools for interpreting cosmic ray data, there is a long standing problem: is seems to be impossible to accommodate at the same time…
Observational constraints on the evolutionary connection between PG 1159 stars and DO white dwarfs
S. D. Huegelmeyer, S. Dreizler, K. Werner +3
The Sloan Digital Sky Survey has provided spectra of a large number of new PG 1159 stars and DO white dwarfs. This increase in known hot H-deficient compact objects significantly i…
Asteroseismological constraints on the pulsating planetary nebula nucleus (PG1159-type) RX J2117.1+3412
A. H. Córsico, L. G. Althaus, M. M. Miller Bertolami +1
We present asteroseismological inferences on RX J2117.1+3412, the hottest known pulsating PG1159 star. Our results are based on full PG1159 evolutionary models recently presented b…
FUSE Spectroscopy of the DAO-type Central Star LS V+4621: Looking for the Photosphere in the Sea of Interstellar Absorption
M. Ziegler, T. Rauch, K. Werner +2
The far-ultraviolet spectrum of the DAO White Dwarf LS V+4621, the exciting star of the possible planetary nebula Sh 2-216,is strongly contaminated by absorption features from the…
