Descripción
We have done a spectroscopical analysis of the type I planetary nebula
(PN) NGC 5315, through high-resolution (R ˜ 40000) optical
spectroscopy with UVES at the 8.2m Very Large Telescope, and
medium-resolution (R ˜ 4800) near-IR spectroscopy with FIRE at the
6.5m Magellan Baade telescope, covering a wide spectral range from 0.31
μm to 2.50μm. The main aim of this work is to investigate the slow
neutron(n)-capture process (the s-process) in the Asymptotic Giant
Branch (AGB) star progenitor of a type I PNe. We detected and identified
about 700 features, including lines from the n-capture elements Kr, Se,
and possibly Br and Xe. We compute physical conditions using line ratios
of common ions. Ionic abundances are computed for the species with
available atomic data. We calculate total abundances using recent
ionization correction factors (ICFs) or by summing ionic abundances. Our
results for common elements are in good agreement with previous works on
the same object. We do not find a substantial s-process enrichment in
NGC 5315, which is typical for type I PNe.
