Abstract:
We present a set of 144 Galactic chemical evolution models applied to
a Milky Way analogue, computed using four sets of low+intermediate
star nucleosynthetic yields, six massive star yield compilations, and
six functional forms for the initial mass function. A comparison is
made between a grid of multiphase chemical evolution models computed
with these yield combinations and empirical data drawn from the Milky
Way's disc, including the solar neighbourhood. By means of a χ2
methodology, applied to the results of these multiphase models, the
best combination of stellar yields and initial mass function capable
of reproducing these observations is identified.
Description:
These tables give the theoretical chemical evolution models applied
for the Milky Way Galaxy (MWG) from the cited paper. Basically give
tables 2, 4 of stellar yields used and results of table 6 for the 144
models computed that work.
Tables 2 and 4 give the stellar yields q_i(m) and remmnant mass for
low and intermediate stars and massive stars, respectively, in a
similar format for all authors.
Table 6 gives the value of Chi2 for the 144 models computed for MWG
using those stellar yields and different Initial Mass Function (see
paper).
Moreover, we give the table with results of the present time state of
the Galactic disk for these 144 models.
