The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): Formaldehyde (HCO) emission and its links to disk properties
Ella Chevalier, Ke Zhang, Miguel Vioque +7
Protoplanetary disks are rotating structures of gas and dust surrounding young stars, serving as the birth places of planets. Understanding the chemical evolution of organic materi…
Evidence for Systematically Larger Dust Grains in Upper Scorpius Relative to Taurus Disks
Yao Liu, Ilaria Pascucci, Fei Gao +10
Infrared spectroscopy provides a powerful diagnostic for probing the mineralogical properties of dust grains in the terrestrial planet-forming regions of protoplanetary disks. The…
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,…
The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): Constraints on disk turbulence, fragmentation velocity, and inner pebble fluxes
Lilian Luo, Paola Pinilla, Camila Pulgarés +14
How substructures and disk properties affect dust evolution and the delivery of solids and volatiles into planet-forming regions remains an open question. We present results from t…
JWST/MIRI Hydrocarbon and Water Absorption in the Wind of a Young Disk: Signatures of Pebble Drift and Carbon Grain Sublimation
MarÃa José Colmenares, Edwin A. Bergin, Ke Zhang +27
We present JWST/MIRI-MRS observations of ISO-Oph 37, a highly inclined flat-spectrum (1 Myr old) source, to investigate the chemical composition and dynamical origin of i…
Compact CO emission and no evidence of radial drift. ALMA observations of the faintest planet-forming disks in Lupus
Giulia Ricciardi, Francesco Zagaria, Anna Miotello +13
A large fraction of planet-forming disks observed with ALMA show faint CO emission, often interpreted as strong CO depletion. However, faint emission may also arise from spatially…
