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…
Extending dynamical mass measurements: probing GI as a possible origin of mm-dust spirals
V. Pezzotta, S. Facchini, A. F. Izquierdo +7
Constraining the total mass of protoplanetary disks is crucial to determine the availability of material for planet formation. Yet, providing accurate and precise measurements of t…
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…
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…
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…
The 12CO Gas Structures of Protoplanetary Disks in the Upper Scorpius Region
Luigi Zallio, Giovanni P. Rosotti, Miguel Vioque +13
We present measurements of key protoplanetary disk properties inferred from parametric models of ALMA 12CO spectral line visibilities. We derive gas-disk radii, integrated fluxes,…
