RXJ0806.3+1527: a double degenerate binary with the shortest known orbital period (321s)
G. L. Israel, W. Hummel, S. Covino +13
We carried out optical observations of the field of the X-ray pulsator RXJ0806.3+1527. A blue V=21.1 star was found to be the only object consistent with the X-ray position. VLT FO…
Reconstruction of emission sites in the dwarf nova EX Draconis
Viki Joergens, Karl-Heinz Mantel, Heinz Barwig +2
We performed time-resolved spectroscopic studies of the double-eclipsing dwarf nova EX Dra (formerly HS 1804 + 6753) in order to locate line emitting sites in the system. Optical s…
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…
Phase-resolved high-resolution spectrophotometry of the eclipsing polar HU Aquarii
Axel D. Schwope, Karl-Heinz Mantel, Keith Horne
We present phase-resolved spectroscopy of the bright, eclipsing polar HU Aqr obtained with high time (~30sec) and spectral (1.6 A) resolution when the system was in a high accretio…
