An SMA Molecular Inventory of the Edge-on Protoplanetary Disk Gomez's Hamburger
Erin M. Cusson, Lisa Wölfer, Richard Teague +10
Gomez's Hamburger (IRAS 18059-3211, GoHam) is a massive, edge-on protoplanetary disk that is potentially gravitationally unstable and hosts an overdensity that may be the site of a…
Compact Hydrogen Sulfide Emission Indicates Sulfur-bearing Ice Sublimation in the Inner Disk of HD 163296
Yoshihide Yamato, Yuri Aikawa, Kenji Furuya +8
The sulfur chemistry in protoplanetary disks directly affects the composition and potential habitability of nascent planets, but its volatile inventory remains highly uncertain. He…
CHOH and HCN in Interstellar Comet 3I/ATLAS Mapped with the ALMA Atacama Compact Array: Distinct Outgassing Behaviors and a Remarkably High CHOH/HCN Production Rate Ratio
Nathan X. Roth, Martin A. Cordiner, Dominique Bockelée-Morvan +15
We report the detection of methanol (CHOH) toward interstellar comet 3I/ATLAS using the Atacama Compact Array of the Atacama Large Millimeter/Submillimeter Array (ALMA) on UT 2…
Isotopic Ratios in the Disk of HD 163296
Chunhua Qi, David J. Wilner, Catherine C. Espaillat
Isotopic abundance ratios in protoplanetary disks are critical for understanding volatile inheritance and chemical evolution in planet-forming environments. We present Atacama Larg…
Tracing Pebble Drift History in Two Protoplanetary Disks with CO Enhancement
Tayt Armitage, Joe Williams, Ke Zhang +15
Pebble drift is an important mechanism for supplying the materials needed to build planets in the inner region of protoplanetary disks. Thus, constraining pebble drift's timescales…
A Submillimeter Survey of CS Excitation in Protoplanetary Disks: Evidence of X-ray-Driven Sulfur Chemistry
Charles J. Law, Romane Le Gal, Karin I. Ãberg +12
The sulfur chemistry in protoplanetary disks influences the properties of nascent planets, including potential habitability. Although the inventory of sulfur molecules in disks has…
