Drift-dominated dust evolution. A multiwavelength analysis of dust rings in CY Tau and DoAr25

Anastasia Topalidou, Nienke van der Marel, Paola Pinilla, Haochang Jiang et autres

Protoplanetary disks are the birthplaces of planets, and understanding the distribution and evolution of dust within them is essential for tracing the early stages of planet formation. Following the DSHARP survey, we aim to constrain the radial distribution of the dust surface …

The ALMA Survey of Gas Evolution of PROtoplanetary Disks (AGE-PRO): Formaldehyde (H 2 CO) Emission and Its Links to Disk Properties

Ella Chevalier, Ke Zhang, Miguel Vioque, N. T. Kurtovic et autres

Abstract 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 materials in these disks is key for tracing the origins of organics in planetary systems. Formaldehyde …

Molecular Similarity and Water Diversity in Coeval Binary Disks: JWST/MIRI Observations of Sz 65 and Sz 66

Jinghuai Yao, Ke Zhang, Andrea Banzatti, Naman S. Bajaj et autres

Abstract We present JWST/MIRI Medium Resolution Spectrometer spectra of the wide-separation (projected separation = 980 au) binary protoplanetary disks Sz 65 (K7; 0.68 M ⊙ ) and Sz 66 (M3; 0.30 M ⊙ ), reduced using the uniform pipeline of the JWST …

Diverse dust vertical height and settling strength conditions in protoplanetary discs

Juanita Antilen, Paola Pinilla, Dafa Li, M. Villenave et autres

ABSTRACT The settling of dust particles plays a critical role in the growth and dynamics of dust grains. Using radiative transfer simulations, we performed detailed modelling of the ALMA continuum substructures for six highly inclined protoplanetary discs to constrain the vertical height …

JWST/MIRI Hydrocarbon and Water Absorption in the Wind of a Young Disk: Signatures of Pebble Drift and Carbon Grain Sublimation

María José Colmenares, Edwin A. Bergin, Ke Zhang, Geoffrey A. Blake et autres

Abstract 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 its inner-disk gas. The spectrum reveals a rich combination of molecular emission and absorption: H 2 O, …

Survival of protoplanetary disks in Upper Scorpius from population synthesis models with external photoevaporation

Jingyi Ping, Rossella Anania, Paola Pinilla, Miguel Vioque

We present population synthesis models of viscous protoplanetary disks subject to mild external far-ultraviolet (FUV) radiation fields ( F UV = 1–100 G 0 ). Our simulations focus on gas-disk evolution, exploring stellar masses drawn from an initial mass function and a …

The ALMA Survey of Gas Evolution of PROtoplanetary discs (AGE-PRO): constraints on disc turbulence, fragmentation velocity, and inner pebble fluxes

L. -W. Luo, Paola Pinilla, Camila Pulgarés, Laura M. Pérez et autres

ABSTRACT How substructures and disc properties affect dust evolution and the delivery of solids and volatiles into planet-forming regions remains an open question. We present results from tailored dust evolution modeling of the AGE–PRO ALMA large program, a sample of 30 protoplanetary …

Observational evidence for a possible link between PAH emission and dust trap locations in protoplanetary disks

Nienke van der Marel, Niels F. W. Ligterink, Ryan van der Werf, Milou Temmink et autres

Context. Polycyclic aromatic hydrocarbons (PAHs) are commonly detected in protoplanetary disks, but it is unclear what causes the wide range of intensities across the samples. Aims. For this work, the measured PAH intensities of a range of disks were compared with ALMA …

Protoplanetary Disk Cavities with JWST-MIRI: A Dichotomy in Molecular Emission

Patrick Mallaney, Andrea Banzatti, Colette Salyk, Ilaria Pascucci et autres

Abstract The evolution of planet-forming regions in protoplanetary disks is of fundamental importance to understanding planet formation. Disks with a central deficit in dust emission, a “cavity,” have long attracted interest as potential evidence for advanced disk clearing by protoplanets and/or winds. …

Models and Observational Predictions of Dust Traps in Protoplanetary Discs

Paola Pinilla

This manuscript investigates the impact of key dust evolution parameters on dust retention and trapping in protoplanetary discs. Using models with and without pressure bumps, combined with radiative transfer simulations, images of the dust continuum emission at (sub-)millimeter wavelengths, their fluxes and …
