SMA Observations Reveal Abundant HNC Chemistry in Transition Disks
Kyle Gresko, Charles J. Law, Deryl E. Long +8
The physical and chemical conditions of protoplanetary disks shape the properties of nascent planetary systems. The line ratios and relative abundances of the HCN-HNC isomer pair a…
Using Scattered Near-Infrared Light to Map Water Ice in Prestellar Cores with SPHEREx
Tamojeet Roychowdhury, Jennifer B. Bergner, Jens Kauffmann +2
We present the first coreshine-derived, spatially-resolved maps of the 3 m HO ice absorption feature in four prestellar cores, using SPHEREx spectra. Ices are a key compone…
JWST Edge-on Disk Ice (JEDIce): Vibrationally hot, rotationally cold H in the outer disk of Oph 163131 non-thermally excited by UV and cosmic rays
Korash Assani, Zhi-Yun Li, Jennifer B. Bergner +19
Constraining ionization and excitation processes in protoplanetary disks is essential for understanding the chemical structure and evolution of disk material, shaping planet format…
CORINOS V: Radiative transfer effects in protostellar ice observations
Will E. Thompson, Jennifer B. Bergner, Neal J. Evans +11
Recent observations of protostars with the James Webb Space Telescope have revealed unprecedented chemical complexity from their ice absorption features. However, these spectra are…
JWST Edge-on Disk Ice (JEDIce): Program overview and ice survey results
Jennifer B. Bergner, Nicole Arulanantham, Emmanuel Dartois +21
The icy material within protoplanetary disks plays a central role in planet formation, yet remains poorly characterized by observations. We present 1.6-28m spectra of five disk…
Functionalization of Benzene Ices by Atomic Oxygen
Elettra L. Piacentino, Alexandra McKinnon, Nora Hänni +6
Small aromatic molecules, including functionalized derivatives of benzene, are known to be present throughout the different stages of star and planet formation. In particular, oxyg…
