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…
Variation of the disk thickness across ice bands: A method to determine ice abundances in highly inclined protoplanetary disks
Laurine Martinien, Gaspard Duchêne, François Ménard +6
The James Webb Space Telescope provides unprecedented information to study ices in protoplanetary disks. However, the saturation of ice bands in highly inclined disks hinders the m…
CoronaGraph Instrument Reference stars for Exoplanets (CorGI-REx) I. Preliminary Vetting and Implications for the Roman Coronagraph and Habitable Worlds Observatory
Justin Hom, Schuyler G. Wolff, Catherine A. Clark +28
The upcoming Roman Coronagraph will be the first high-contrast instrument in space capable of high-order wavefront sensing and control technologies, a critical technology demonstra…
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…
The grazing angle icy protoplanetary disk PDS 453
Laurine Martinien, François Ménard, Gaspard Duchêne +12
PDS 453 is a rare highly inclined disk where the stellar photosphere is seen at grazing incidence on the disk surface. Our goal is take advantage of this geometry to constrain the…
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…
