If such an O+Ne+Mg core grows to 1.38 $M_\\odot$, electron captures on $^{20}$Ne$(e,\\nu_e)^{20}$F$(e,\\nu_e)^{20}$O take place and ignite O-Ne deflagration around the center. In this paper, we perform two-dimensional hydrodynamics simulations of the propagation of the O-Ne flame to see whether such a flame induces a collapse of the O+Ne+Mg core due to subsequent electron capture behind the flame or triggers a thermonuclear explosion.
