Query: Matter Mixing in Axisymmetric Supernova Explosion   Growth of Rayleigh-Taylor (R-T) instabilities under the axisymmetric
explosion are investigated by two-dimensional hydrodynamical calculations. The
degree of the axisymmetric explosion and amplitude of the initial perturbation
are varied parametrically to find the most favorable parameter for reproducing
the observed line profile of heavy elements. It is found that spherical
explosion can not produce $^{56}Ni$ travelling at high velocity ($\sim
3000$km/sec), the presence of which is affirmed by the observation, even if the
amplitude of initial perturbation is as large as 30%. On the other hand, strong
axisymmetric explosion model produce high velocity $^{56}Ni$ too much. Weak
axisymmetric explosion are favored for the reproduction of the observed line
profile. We believe this result shows upper limit of the degree of the
axisymmetric explosion. This fact will be important for the simulation of the
collapse-driven supernova including rotation, magnetic field, and axisymmetric
neutrino radiation, which have a possibility to cause axisymmetric supernova
explosion. In addition, the origin of such a large perturbation does not seem
to be the structure of the progenitor but the dynamics of the core collapse
explosion itself since small perturbation can not produce the high velocity
element even if the axisymmetric explosion models are adopted.
