X-rays from Cataclysmic Variables
Erik Kuulkers, Andrew Norton, Axel Schwope +1
Cataclysmic Variables are a distinct class of interacting binaries, transferring mass from a donor star to a degenerate accretor, a white dwarf. We here review X-ray observations o…
The XMM-Newton Bright Serendipitous Source Sample (XMM-Newton BSS)
R. Della Ceca, T. Maccacaro, A. Caccianiga +15
The XMM-Newton Survey Science Center is constructing a large (~1000 sources) and complete sample of bright serendipitous XMM-Newton sources at high galactic latitude, so as to allo…
RX J1313.2-3259, a long-period Polar discovered with ROSAT
H. -C. Thomas, K. Beuermann, V. Burwitz +2
We report observations of a new AM Herculis binary identified as the optical counterpart of the X-ray source RX J1313.2-3259, detected during the ROSAT All-Sky Survey (RASS). It ha…
Zeeman lines and a single cyclotron line in the low-accretion rate polar 1RXS J012851.9-233931 (RBS0206)
A. D. Schwope, R. Schwarz, J. Greiner
We present a low-resolution discovery spectrum and CCD-photometry of the bright X-ray source 1RXS J012851.9-233931 found in the ROSAT All-Sky Survey. These first observations sugge…
The isolated neutron star candidate RBS1223 (1RXS J130848.6+212708)
A. D. Schwope, G. Hasinger, R. Schwarz +2
In the ROSAT Bright Survey (RBS) we have almost completely optically identified the brightest ~2000 high-galactic latitude sources from the ROSAT All-Sky Survey Bright Source Catal…
AGN/galaxy separation in the ROSAT Bright Survey
I. Lehmann, G. Hasinger, A. D. Schwope +1
The X-ray luminosity function (XLF) of galaxies is dominated by AGN (classified by their optical spectra) above Lx=10**42 erg/s, below this value by normal galaxies. The X-ray flux…
