Current and secular accretion rates of EX Hydrae
K. Beuermann, K. Reinsch
We report an observed accretion rate of yr for the white dwarf in the short-period, intermediate polar EX Hya. This resu…
An Eccentric Planet Orbiting the Polar V808 Aurigae
McKenna Leichty, Peter Garnavich, Colin Littlefield +4
We analyze 15 years 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…
High-resolution spectroscopy of the intermediate polar EX Hydrae: II. The inner disk radius
K. Beuermann, K. Reinsch
EX Hya is one of the best studied, but still enigmatic intermediate polars. We present phase-resolved blue VLT/UVES high-resolution () spectra of EX Hya taken in…
GW Librae: A unique laboratory for pulsations in an accreting white dwarf
O. Toloza, B. T. Gaensicke, J. J. Hermes +22
Non-radial pulsations have been identified in a number of accreting white dwarfs in cataclysmic variables. These stars offer insight into the excitation of pulsation modes in atmos…
Evidence for an oscillation of the magnetic axis of the white dwarf in the polar DP Leonis
K. Beuermann, S. Dreizler, F. V. Hessman +1
From 1979 to 2001, the magnetic axis of the white dwarf in the polar DP Leo slowly rotated by 50 deg in azimuth, possibly indicating a small asynchronism between the rotational and…
The eclipsing post-common envelope binary CSS21055: a white dwarf with a probable brown-dwarf companion
K. Beuermann, S. Dreizler, F. V. Hessman +6
We report photometric observations of the eclipsing close binary CSS21055 (SDSS J141126+200911) that strongly suggest that the companion to the carbon-oxygen white dwarf is a brown…
