Abstract
Stability of accretion onto magnetic white dwarfs is investigated via
perturbation analysis. We consider a cooling function with composite p
ower laws, and the power-law indices are appropriate for bremsstrahlun
g and optically thick cyclotron cooling. We find that the presence of
cyclotron cooling generally suppresses the instability, consistent wit
h numerical simulations by other investigators.
