A breath of fresh air: Oxygen enhancement from silicate sublimation during early protostellar evolution
F. J. Ballieux, M. K. McClure, Ł. Tychoniec +5
Recently, an analog to the t = 0 moment of our Solar System's meteoritic record was identified for the first time around the Class I protostar HOPS-315. Crystalline silicates were…
The Fast & Fourier: Using neural operators to speed up radiative modeling of protoplanetary disks
Lukas Welzel, Melissa K. McClure
Edge-on protoplanetary disks provide a spatially resolved view of the vertical distribution of icy planetary building blocks, but inferring their relative abundances requires radia…
Mapping of interstellar ices with JWST in protostellar envelopes: Spatial variations of CO, CO, CO, OCN and HO ice
N. G. C. Brunken, E. F. van Dishoeck, A. C. A. Boogert +16
The composition of planets and their atmospheres is largely determined by the formation environment of the planet. This environment is pre-determined during early stages when the p…
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…
Probing the ubiquity of complex ices in protostars with JWST: the first systematic quantification of weak ice bands between 6.8 and 7.9 micron
Yuan Chen, Ewine F. van Dishoeck, Katerina Slavicinska +18
Complex organic molecules (COMs) are the key to understanding the chemical evolution from simple interstellar molecules to potential prebiotic material. Although COMs have been ext…
MINDS: Complementary inclinations in the binary system HK Tau reveal gas- and ice-phase chemistry
Alice Somigliana, Giulia Perotti, Nicolás T. Kurtovic +18
[Abridged] HK Tau is a roughly equal mass pre-main sequence binary system consisting of a low-inclination primary (57 deg) and an edge-on (83 deg) secondary. We present JWST/MIRI o…
Implications of self-consistent HO ice optical constants on radiative transfer models of disks
Z. L. Smith, M. K. McClure, I. Kamp +1
Interstellar water (HO) ice exhibits significantly varied profiles over its spectral features with temperature and thermal history. No previous radiative transfer model of a pr…
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 disks…
