Patterson, J. ; Beuermann, K. ; Lamb, D. W. ; Fabbiano, G. ; Raymond, J. C. ; Swank, J. ; White, N. E. Abstract The authors report X-ray and ultraviolet observations of the AM Herculis-type binary VV Puppis, which show it to be a spectacular source at soft X-ray energies (0.1 - 0.3 keV), but only weakly detected in hard X-rays and in the ultraviolet. The orbital light curves in soft and hard X-rays are in good agreement with the mean optical light curve, indicating that essentially all the accretion luminosity originates from a small region (⪉100 km) near one of the magnetic poles of the white dwarf. The total energy distribution reveals four distinct components, peaking at infrared, optical/UV, soft X-ray, and hard X-ray energies.
