Absorption-Line Spectroscopy of Planetary Nebulae with FUSE: Probing the Molecular, Atomic, and Ionized Gas
Harriet L. Dinerstein, N. C. Sterling, Charles W. Bowers
The central stars of planetary nebulae (PNe) are natural targets for FUSE due to their UV brightness. The FUSE spectra of many PNe show absorption features due to circumstellar mat…

An Infrared Survey of Neutron-Capture Elements in Planetary Nebulae
N. C. Sterling, H. L. Dinerstein
We present results from an ongoing survey of infrared emission lines from the neutron-capture elements Se and Kr in Galactic planetary nebulae (PNe). Se and Kr may be produced in t…
