Abstract:
This is the second paper of a series reporting the results from the
popstar evolutionary synthesis models. Here, we present synthetic
emission-line spectra of HII regions photoionized by young star
clusters, for seven values of cluster masses and for ages between 0.1
and 5.2Myr. The ionizing spectral energy distributions (SEDs) are
those obtained by the popstar code for six different metallicities,
with a very low-metallicity set, Z=0.0001 , not included in previous
similar works. We assume that the radius of the HII region is the
distance at which the ionized gas is deposited by the action of the
mechanical energy of the winds and supernovae from the central
ionizing young cluster.
Description:
Table 1 gives the abundances used to compute the photoionization
models of different metallicities. Table 2a gives the complete
results for these models, the emission lines intensities, the
parameter U and the radius of the corresponding HII region for
an electronic density of 10cm-1. Table 2b gives the same results
for a density of 100cm-1.
