Abstract:
We present a new and homogeneous set of explosive yields for masses
13, 15, 20, 25, 30, and 35M☉ and metallicities Z=0, 10-6,
10-4, 10-3, 6x10-3, and 2x10-2. 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.
