Abstract:
In this, the third of a series of papers, we present well determined
chemical abundances for 124 Planetary nebulae (PNe) in the Galactic
bulge from deep, long-slit FORS2 spectra from the 8.2 m ESO Very Large
telescope (VLT). Prior to this work there were only ∼240 bulge PNe
with chemical abundances previously determined over a ∼50 year
period and of highly variable quality. For 34 of these PNe we are
presenting their abundances for the first time which adds ∼14% to
the available sample of bulge PNe abundances. The interstellar
reddening, physical conditions (electron densities, ne,
temperatures, Te), and chemical compositions are derived as single
values for each PN but also using different line diagnostics. Selected
comparisons with the best literature fluxes for 75 PNe in common
reveals that these significant new data are robust, reliable and
internally self-consistent forming the largest independent, high
quality and well understood derivation of PNe abundances currently
available for study.
Description:
The long-slit spectroscopic observations used in this study were
conducted with the FORS2 instrument on the 8m ESO VLT/UT1 between
April 2015 and July 2018 under program IDs 095.D-0270(A),
097.D-0024(A), 099.D-0163(A), and 0101.D-0192(A) with PI Rees and
co-Is Zilstra and Parker.
We present the ionic abundances of the sample in catalog.dat.
