The disk vanishes
Jean-Marie Hameury, Jean-Pierre Lasota
Recently published observations of VY Scl stars in their low, long-intermediate and high states confirm our model (Hameury & Lasota 2002) according to which accretion disks in such…
Disc radius variations in binaries
Jean-Marie Hameury, Jean-Pierre Lasota
A thermal/viscous instability of the accretion disc arising when hydrogen is partially ionized is the most popular explanation of the outbursts of both dwarf novae (DN) and soft X-…
Predictions of the disc instability model
M. R. Schreiber, J. -M. Hameury, J. -P. Lasota
Confronting the predictions of numerical calculations with observations is an important tool to progress with our understanding of the mechanism triggering the outbursts of dwarf n…
The zoo of dwarf novae : illumination, evaporation and disc radius variation
Jean-Marie Hameury, Jean-Pierre Lasota, Brian Warner
In the framework of the dwarf nova thermal-viscous disc instability model, we investigate the combined effects on the predicted dwarf nova lightcurves of irradiating the accretion…
Disc instability models, evaporation and radius variations
Jean-Marie Hameury, Guillaume Dubus, Jean-Pierre Lasota +1
We show that the outcome of disc instability models is strongly influenced by boundary conditions such as the position of the inner and outer disc edges. We discuss other sources o…
