Observations of highly inclined disks with ALMA. Results from 12CO gas and continuum observations
Laurine Martinien, Gaspard Duchêne, Álvaro Ribas +4
[Abridged] We aim to study the radial and vertical extents of 12CO gas, millimeter dust thermal emission and optical/NIR scattered light by dust in disks. We analyze a sample of 14…
Dust traps and gas kinematic signatures in a crescent structure of a planet-forming disk
Greta Guidi, François Menard, Daniel J. Price +2
In the past few years, ALMA unveiled a variety of substructures (rings, spirals, crescents) in the continuum emission of most protoplanetary disks imaged at high spatial resolution…
Benchmarking pre-main sequence stellar evolutionary tracks using disk-based dynamical stellar masses
Luigi Zallio, Miguel Vioque, Sean M. Andrews +14
Stellar masses are a fundamental property to understand models of pre-main sequence evolution, but their values derived from Hertzsprung-Russell (HR) diagrams are strongly model de…
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,…
An Introduction to Dust Evolution and Vertical Transport in Protoplanetary Disks
Marion Villenave
This tutorial is an introduction to observational studies of dust transport and evolution in protoplanetary disks. Spatially resolved observations of disks at multiple wavelengths…
Asymmetric Signatures of Warps in Edge-on Disks
Carolin N. Kimmig, Marion Villenave
Protoplanetary disks observed edge-on commonly show asymmetries that can be caused by shadows cast from a warp. With the growing amount of these observations, methods to constrain…
Turbulence in protoplanetary disks: A systematic analysis of dust settling in 33 disks
M. Villenave, G. Rosotti, M. Lambrechts +7
The level of dust vertical settling and radial dust concentration in disks is of critical importance for understanding the efficiency of planet formation. We present the first unif…
JWST imaging of edge-on protoplanetary disks. III. Drastic morphological transformation across the mid-infrared in Oph163131
Marion Villenave, Karl R. Stapelfeldt, Gaspard Duchene +6
We present JWST broadband images of the highly inclined protoplanetary disk SSTc2d J163131.2-242627 (Oph163131) from 2.0 to 21m. The images show a remarkable evolution in disk s…
JWST imaging of edge-on protoplanetary disks II. Appearance of edge-on disks with a tilted inner region: case study of IRAS04302+2247
M. Villenave, K. R. Stapelfeldt, G. Duchene +6
We present JWST imaging from 2m to 21m of the edge-on protoplanetary disk around the embedded young star IRAS04302+2247. The structure of the source shows two reflection nebu…
Modest dust settling in the IRAS04302+2247 Class I protoplanetary disk
M. Villenave, L. Podio, G. Duchene +11
We present new VLA observations, between 6.8mm and 66mm, of the edge-on Class~I disk IRAS04302+2247. Observations at 6.8mm and 9.2mm lead to the detection of thermal emission from…
A highly settled disk around Oph 163131
M. Villenave, K. R. Stapelfeldt, G. Duchene +10
High dust density in the midplane of protoplanetary disks is favorable for efficient grain growth and can allow fast formation of planetesimals and planets, before disks dissipate.…
Circumbinary and circumstellar discs around the eccentric binary IRAS 04158+2805 -- a testbed for binary-disc interaction
Enrico Ragusa, Daniele Fasano, Claudia Toci +10
IRAS~04158+2805 has long been thought to be a very low mass T-Tauri star (VLMS) surrounded by a nearly edge-on, extremely large disc. Recent observations revealed that this source…
Probing protoplanetary disk evolution in the Chamaeleon II region
M. Villenave, F. Menard, W. R. F. Dent +13
Context. Characterizing the evolution of protoplanetary disks is necessary to improve our understanding of planet formation. Constraints on both dust and gas are needed to determin…
The Anatomy of an Unusual Edge-on Protoplanetary Disk. II. Gas temperature and a warm outer region

We present high-resolution CO and CO 2-1 ALMA observations, as well as optical and near-infrared spectroscopy, of the highly-inclined protoplanetary disk around SSTC2…
The Anatomy of an Unusual Edge-on Protoplanetary Disk I. Dust Settling in a Cold Disk
S. Wolff, G. Duchêne, K. Stapelfeldt +7
As the earliest stage of planet formation, massive, optically thick, and gas rich protoplanetary disks provide key insights into the physics of star and planet formation. When view…

Gap, shadows, spirals, streamers: SPHERE observations of binary-disk interactions in GG Tau A
M. Keppler, A. Penzlin, M. Benisty +31
A large fraction of stars is found to be part of binary or higher-order multiple systems. The ubiquity of planets found around single stars raises the question if and how planets i…
