XMM-Newton observation of the long-period polar V1309 Ori: The case for
pure blobby accretion
, 2005 Using XMM-Newton we have obtained the first X-ray observation covering a
complete orbit of the longest period polar, V1309 Ori. The X-ray light curve is
dominated by a short, bright phase interval with EPIC pn count rates reaching
up to 15 cts/sec per 30 Aizu, Araujo-Betancor, Beuermann, Beuermann, Beuermann, Beuermann, Buckley, Burwitz, Clayton, Cropper, de Martino, Done, Frank, Frank, Gänsicke, Hameury, Hameury, Heise, Heise, K.

The Astrophysical JournalWe analyze 15 yr of eclipse timings of the polar V808 Aur. The rapid ingress/egress of the white dwarf and bright accretion region provide timings as precise as a few tenths of a second for rapid cadence photometric data.McKenna Leichty, Peter Garnavich, Colin Littlefield, Axel Schwope, Jan Kurpas, Paul A.

one-dimensional stationary radiation hydrodynamics
