Fast quasi-periodic oscillations in the eclipsing polar VV Puppis from VLT and XMM-Newton observations
J. M. Bonnet-Bidaud, M. Mouchet, E. Falize +7
We present high time resolution optical photometric data of the polar VV Puppis obtained simultaneously in three filters (u', HeII 4686, r') with the ULTRACAM camera mounted at…
Quasi-periodic oscillations in accreting magnetic white dwarfs I. Observational constraints in X-ray and optical
J. M. Bonnet-Bidaud, M. Mouchet, C. Busschaert +2
Quasi-periodic oscillations (QPOs) are observed in the optical flux of some polars with typical periods of 1 to 3 s but none have been observed yet in X-rays where a significant pa…
Laboratory radiative accretion shocks on GEKKO XII laser facility for POLAR project
L. Van Box Som, E. Falize, M. Koenig +20
A new target design is presented to model high-energy radiative accretion shocks in polars. In this paper, we present the experimental results obtained on the GEKKO XII laser facil…
Quasi-periodic oscillations in accreting magnetic white dwarfs II. The asset of numerical modelling for interpreting observations
C. Busschaert, E. Falize, C. Michaut +2
Magnetic cataclysmic variables are close binary systems containing a strongly magnetized white dwarf that accretes matter coming from an M-dwarf companion. High-energy radiation co…
Experiments to investigate the effects of radiative cooling on plasma jet collimation
C. D. Gregory, A. Diziere, H. Aoki +15
Preliminary experiments have been performed to investigate the effects of radiative cooling on plasma jets. Thin (3 um - 5 um) conical shells were irradiated with an intense laser,…
A VLT-ULTRACAM study of the fast optical quasi-periodic oscillations in the polar V834 Centauri
M. Mouchet, J. -M. Bonnet-Bidaud, L. Van Box Som +6
Quasi-periodic oscillations (QPOs) of a few seconds have been detected in some Polars, the synchronised subclass of cataclysmic systems containing a strongly magnetised white dwarf…
