Explosive yields of massive stars from Z = 0 to Z = Zsolar

We present a new and homogeneous set of explosive yields for masses 13, 15, 20, 25, 30, and 35 Msun and metallicities Z = 0, 10-6, 10-4, 10-3, 6 x 10-3, and 2 x 10-2. A wide network extending up to Mo has been used in all computations. We show that at low metallicities (Z ≤ 10-4), the final yields do not depend significantly on the initial chemical composition of the models, so a scaled solar distribution may be safely assumed at all metallicities. Moreover, no elements above Zn are produced by any mass in the grid up to a metallicity ~10-3. These yields are available for any choice of the mass cut on request.
