New bright soft X-ray selected ROSAT AGN: I. Infrared-to-X-ray spectral energy distributions
D. Grupe, K. Beuermann, H. -C. Thomas +2
We present results of an infrared-to-X-ray study of 76 bright soft X-ray selected Seyfert galaxies discovered in the ROSAT All-Sky Survey. These objects are characterized by steep…
Polars -- multisite emission -- multiwavelength observation
Axel D. Schwope, K. Beuermann, D. A. H. Buckley +12
We review the main observational characteristics of AM Herculis stars (polars) at X-ray, EUV, UV, IR and optical wavelengths. Particular emphasis is given to multi-epoch, multi-wav…
On the mass of the white dwarf in UZ Fornacis
Axel D. Schwope, Sabine Mengel, Klaus Beuermann
We present phase-resolved spectroscopy of the eclipsing AM Herculis star UZ For obtained when the system was in its low state of accretion. Faint residual Halpha-emission and NaI a…
