Ionization by Massive Young Clusters as Revealed by Ionization-Parameter Mapping
M. S. Oey, E. W. Pellegrini, J. Zastrow +1
Ionization-parameter mapping (IPM) is a powerful technique for tracing the optical depth of Lyman continuum radiation from massive stars. Using narrow-band line-ratio maps, we exam…

Abundances of s-process elements in planetary nebulae: Br, Kr & Xe
Y. Zhang, R. Williams, E. Pellegrini +5
We identify emission lines of post-iron peak elements in very high signal-to-noise spectra of a sample of planetary nebulae. Analysis of lines from ions of Kr and Xe reveals enhanc…
