Accretion from debris disks onto white dwarfs : Fingering (thermohaline) instability and derived accretion rates

Context. Recent observations of a large number of DA and DB white dwarfs show evidence of debris disks, which are the remnants of old planetary systems. The infrared excess detected with <i>Spitzer</i> and the lines of heavy elements observed in their atmospheres with high-resolution spe...
