Mass distributions of ⁴He, ¹²C, ¹⁴N, ¹⁶O, ²⁰Ne, ²⁴Mg, ²⁸Si, ⁴⁰Ca, ⁴⁴Ti, and ⁵⁶Ni versus radialvelocity, V_rad, for models M80 at the time they reach their maximum degree of asymmetry. The figure shows models either with low (upper panels) or high (lower panels) explosion energy, and models either without (on the left) or with (on the right) initial rotation velocity of the star.
