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 =…

Recent measurements of carbon isotope ratios in both protoplanetary disks and exoplanet atmospheres have suggested a possible transfer of significant carbon isotope fractionation f…
JWST-MIRI Spectroscopy of Warm Molecular Emission and Variability in the AS 209 Disk
Carlos E. Romero-Mirza, Karin I. Öberg, Andrea Banzatti +24
We present MIRI MRS observations of the large, multi-gapped protoplanetary disk around the T-Tauri star AS 209. The observations reveal hundreds of water vapor lines from 4.9 to 25…
High turbulence in the IM Lup protoplanetary disk: Direct observational constraints from CN and CH emission
T. Paneque-Carreño, A. F. Izquierdo, R. Teague +4
Constraining turbulence in disks is key towards understanding their evolution through the transport of angular momentum. Until now measurements of high turbulence have remained elu…
MAPS: Constraining Serendipitous Time Variability in Protoplanetary Disk Molecular Ion Emission
Abygail R. Waggoner, L. Ilsedore Cleeves, Ryan A. Loomis +12
Theoretical models and observations suggest that the abundances of molecular ions in protoplanetary disks should be highly sensitive to the variable ionization conditions set by th…
A magnetically driven disc wind in the inner disc of PDS 70
Justyn Campbell-White, Carlo F. Manara, Myriam Benisty +10
PDS 70 is so far the only young disc where multiple planets have been detected by direct imaging. The disc has a large cavity when seen at sub-mm and NIR wavelengths, which hosts t…
Tentative co-orbital submillimeter emission within the Lagrangian region L5 of the protoplanet PDS 70 b
Olga Balsalobre-Ruza, Itziar de Gregorio-Monsalvo, Jorge Lillo-Box +6
Context: High-spatial resolution Atacama Large Millimeter/submillimeter Array (ALMA) data have revealed a plethora of substructures in protoplanetary disks. Some of those features…
Constraining the gas distribution in the PDS 70 disk as a method to assess the effect of planet-disk interactions
