Abstract

We have followed numerically the evolution of a thermally unstable blob in two dimensions. This analysis is related to the problem of the excess of accreting mass in cooling flows. We have introduced in a homogeneous medium a non-spherical entropy perturbation, and we have found that it evolves to form a flat, pancake-like blob with density ~ 100 times the initial one.
