The s-process at Subsolar Metallicity: Insights from High-Resolution Infrared Spectroscopy of Magellanic Cloud Planetary Nebulae
N. C. Sterling, M. G. Stephenson, Harriet L. Dinerstein +8
We present observations of 12 Magellanic Cloud planetary nebulae (PNe) obtained with the high-resolution near-infrared spectrometer IGRINS on Gemini South. In 10 targets we detect…
Rubidium Abundances in Cool Giants from High-Resolution H-band Spectra: A New Diagnostic for Galactic Chemical Evolution
Nils Ryde, Jess Kocher, Govind Nandakumar +6
The Galactic Center and inner disk of the Milky Way contain complex stellar populations obscured by heavy dust extinction. To study their chemical composition, high-resolution near…
10 Years of Archival High-Resolution NIR Spectra: The Raw and Reduced IGRINS Spectral Archive (RRISA)
Erica Sawczynec, Kyle F. Kaplan, Gregory N. Mace +20
The Immersion GRating INfrared Spectrometer (IGRINS) is a compact, high-resolution (R~45,000) near-infrared spectrograph spanning 1.45 to 2.45 um in a single exposure. We introduce…
High spectral resolution observations of Uranus' near-IR thermospheric emission spectrum using the IGRINS spectrograph during the 2018 and 2023 apparition
Laurence Trafton, Kyle Kaplan
Ground-based near-IR observations have revealed that Uranus anomalously hot upper atmosphere, detected by Voyager 2, has been steadily cooling. The observed and emiss…
