Studying the Fullerene Nest: JWST Observations of the Planetary Nebula Tc 1. III. Tracing Fullerene-Linked Dust Variation
Simon Van Schuylenbergh, Jan Cami, Els Peeters +27
We have observed the fullerene-rich planetary nebula Tc 1 with the MIRI/MRS on JWST. The mid-infrared spectra of this spatially resolved source reveal that the dust emission is not…
Studying the Fullerene Nest: JWST Observations of the Planetary Nebula Tc 1. II. A Spectroscopic and Spatial Study of C and C Emission
M. M. Giese, J. Cami, S. Van Schuylenbergh +31
We present a detailed analysis of the fullerene emission bands in JWST MIRI/MRS observations of the planetary nebula Tc 1. The observations reveal the emission features due to neut…
Detection of C Combination Bands in the Near-IR Spectrum of Tc 1
Morgan M. Giese, Vincent J. Esposito, Simon Van Schuylenbergh +26
We report the detection of a set of new near-infrared emission features between 3.5 and 5.2 m in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying the…
Identification of Near-Infrared [Se III] and [Kr VI] Emission Lines in Planetary Nebulae
N. C. Sterling, S. Madonna, K. Butler +5
We identify [Se III] 1.0994 micron in the planetary nebula (PN) NGC 5315 and [Kr VI] 1.2330 micron in three PNe, from spectra obtained with the FIRE spectrometer on the 6.5-m Baade…
Neutron-Capture Element Abundances in Magellanic Cloud Planetary Nebulae
A. L. Mashburn, N. C. Sterling, S. Madonna +3
We present near-infrared spectra of ten planetary nebulae (PNe) in the Large and Small Magellanic Clouds (LMC and SMC), acquired with the FIRE and GNIRS spectrometers on the 6.5-m…
Discovery of Rubidium, Cadmium, and Germanium Emission Lines in the Near-Infrared Spectra of Planetary Nebulae
N. C. Sterling, Harriet L. Dinerstein, Kyle F. Kaplan +1
We identify [Rb IV] 1.5973 and [Cd IV] 1.7204 micron emission lines in high-resolution (R=40,000) near-infrared spectra of the planetary nebulae (PNe) NGC 7027 and IC 5117, obtaine…
Improved Neutron-Capture Element Abundances in Planetary Nebulae
N. C. Sterling, H. L. Dinerstein, S. Hwang +11
Spectroscopy of planetary nebulae (PNe) provides the means to investigate s-process enrichments of neutron(n)-capture elements that cannot be detected in asymptotic giant branch (A…
