X-ray Variability of Active Galactic Nuclei and the Flare Model
R. W. Goosmann, B. Czerny, A. -M. Dumont +4
Short-term variability of X-ray spectra has been reported for several Active Galactic Nuclei. Significant X-ray flux variations are observed within time scales down to 10^4 -- 10^5…
X-ray Variability of AGN and the Flare Model
R. W. Goosmann, B. Czerny, A. -M. Dumont +2
Short-term variability of X-ray continuum spectra has been reported for several Active Galactic Nuclei. Significant X-ray flux variations are observed within time scales down to 10…
Far-UV FUSE spectra of peculiar magnetic cataclysmic variables
Martine Mouchet, Jean-Marc Bonnet-Bidaud, Evelyne Roueff +11
We present far-UV spectra of the three magnetic cataclysmic variables (MCVs) BY Cam, V1309 Ori and AE Aqr obtained with the FUSE satellite. These MCVs have revealed strongly unusua…
The CNO problem in magnetic cataclysmic variables
Jean-Marc Bonnet-Bidaud, Martine Mouchet
Some magnetic CVs like BY Cam are characterized by unusual CNO line ratios compared to other polars and non-solar abundances have been suggested to explain this anomaly. We present…
