Isotopologues play an important role in solar system cosmochemistry studies, revealing details of early planet formation physics and chemistry. Oxygen isotopes, as measured in sola…
The chemical diversity of giant-planet nurseries as revealed by ALMA
Alice S. Booth, Jenny Calahan, Milou Temmink +9
With the giant exoplanet occurrence rate peaking around stars of 1.5-2 solar masses, there is strong motivation to characterize the disks that set their formation conditions. Obser…
The Impact of External Radiation on the Inner Disk Chemistry of Planet Formation
Jenny K. Calahan, Karin Öberg, Alice Booth
The vast majority of young stars hosting planet-forming disks exist within clustered environments, like the Orion Nebula, implying that seemingly `extreme' UV environments (10^4 G_…

JWST/MIRI detection of a carbon-rich chemistry in a solar nebula analog
Maria Jose Colmenares, Edwin Bergin, Colette Salyk +16
It has been proposed, and confirmed by multiple observations, that disks around low mass stars display a molecule-rich emission and carbon-rich disk chemistry as compared to their…
Complex Organics Surrounding the FU Ori-Type Object V1057 Cyg Indicative of Sublimated Ices
Jenny K. Calahan, Edwin A. Bergin, Merel van't Hoff +5
FU Ori and EX Lup type objects present natural experiments for understanding a critical stage in the star and planet formation process. These objects offer insight into the diversi…
High Mass Inner Regions Found in Five Outbursting Sources
Jenny K. Calahan, Edwin A. Bergin, Merel van't Hoff +3
Young stellar objects are thought to commonly undergo sudden accretion events that result in a rise in bolometric luminosity. These outbursts likely coincide with the onset of plan…
Retrieval of Thermally-Resolved Water Vapor Distributions in Disks Observed with JWST-MIRI
Carlos E. Romero-Mirza, Andrea Banzatti, Karin I. Öberg +13
The mid-infrared water vapor emission spectrum provides a novel way to characterize the delivery of icy pebbles towards the innermost ( au) regions of planet-forming disks. Rec…
The Carbon Isotopic Ratio and Planet Formation
Edwin A. Bergin, Arthur Bosman, Richard Teague +6
We present the first detection of 13CCH in a protoplanetary disk (TW Hya). Using observations of C2H we measure CCH/13CCH = 65 +/- 20 in gas with a CO isotopic ratio of 12CO/13CO =…
