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…
Angular Momentum of Planet-Forming Disks: Implications for Infall Driven Misalignments
Aashish Gupta, Cristiano Longarini, L. Ilsedore Cleeves +5
Context. A significant fraction (>30%) of planet-forming disks and planetary are misaligned with respect to the rotational axis of their host stars, yet the dominant mechanism resp…
First Detection of HC5N in a Class II Disk around TW Hya
Steven C. Wampler, Ryan A. Loomis, Amina Diop +9
Over the last decade of ALMA's operation the molecular inventory of protoplanetary disks has expanded rapidly, revealing a diverse set of nitrogen-bearing organics and carbon-chain…
JWST-DECO: The Impact of Accretion on Mid-Infrared Observable Water in Planet-forming Disks
Jenny K. Calahan, Tarisai Dziire, Karin Ãberg +13
The inner few au of a protoplanetary disk hosts the majority of observed exoplanets and is the primary planet-forming zone of the disk. The mid-IR spectra of disks, with its rich f…
Characterizing the Extended Molecular Hydrogen Winds in Protoplanetary Disks from the JWST Disk Infrared Spectroscopic Chemistry Survey
Mayank Narang, Klaus M. Pontoppidan, Colette Salyk +14
We present a comprehensive analysis of extended H emission from 34 protoplanetary disks observed with the JWST Disk Infrared Spectroscopic Chemistry Survey (JDISCS), supplement…
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…
