The ALMA View of the Edge-on Gomez's Hamburger System: A Highly-Dynamic, Asymmetric Protoplanetary Disk Reveals the Earliest Phases of Giant Planet Formation

Charles J. Law, Jensen Lawrence, Richard Teague +18

Chemical tracers provide some of the strongest observational signatures of ongoing planet formation and localized dynamical perturbations in protoplanetary disks. In particular, su…

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…

HO in the terrestrial planet-forming regions of protoplanetary disks

Colette Salyk, Klaus M. Pontoppidan, Ke Zhang +12

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…

A Submillimeter Survey of CS Excitation in Protoplanetary Disks: Evidence of X-ray-Driven Sulfur Chemistry

Charles J. Law, Romane Le Gal, Karin I. Öberg +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…

ExoALMA XIII. gas masses from N2H+ and C18O: a comparison of protoplanetary gas disk mass measurement techniques

Leon Trapman, Cristiano Longarini, Giovanni P. Rosotti +37

The gas masses of protoplanetary disks are important but elusive quantities. In this work we present new ALMA observations of N2H+ (3-2) for 11 exoALMA disks. N2H+ is a molecule se…

A Multi-line Analysis of the Distribution and Excitation of CS and HCS in the HD 163296 Disk

Charles J. Law, Romane Le Gal, Yoshihide Yamato +6

The abundance and distribution of sulfur-bearing molecules in protoplanetary disks directly influences the composition and potential habitability of nascent planets in addition to…

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…

Chemistry in Protoplanetary Disks

Ke Zhang

Planets are formed inside disks around young stars. The gas, dust, and ice in these natal disks are the building materials of planets, and therefore their compositions fundamentall…

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 =…

Molecular Gas Tracers in Young and Old Protoplanetary Disks

Dana E. Anderson, L. Ilsedore Cleeves, Geoffrey A. Blake +6

Molecular emission is used to investigate both the physical and chemical properties of protoplanetary disks. Therefore, to accurately derive disk properties, we need a thorough und…

Identification of Carbon Stars from LAMOST DR7

Linlin Li, Kecheng Zhang, Wenyuan Cui +6

Carbon stars are excellent kinematic tracers of galaxies and play important roles in understanding the evolution of the Galaxy. Therefore, it is worthwhile to search for them in a…

High-contrast JWST-MIRI spectroscopy of planet-forming disks for the JDISC Survey

Klaus M. Pontoppidan, Colette Salyk, Andrea Banzatti +26

The JWST Disk Infrared Spectral Chemistry Survey (JDISCS) aims to understand the evolution of the chemistry of inner protoplanetary disks using the Mid-InfraRed Instrument (MIRI) o…

Hydrocarbon emission rings in protoplanetary disks induced by dust evolution

Edwin A. Bergin, Fujun Du, L. Ilsedore Cleeves +4

We report observations of resolved C2H emission rings within the gas-rich protoplanetary disks of TW Hya and DM Tau using the Atacama Large Millimeter Array (ALMA). In each case th…
