Observations of highly inclined disks with ALMA. Results from 12CO gas and continuum observations
Laurine Martinien, Gaspard Duchêne, Ãlvaro 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…
The Flying Saucer edge-on disc's Near Infrared silhouette revealed by the JWST JEDIce program
Emmanuel Dartois, Jennifer A. Noble, Jennifer B. Bergner +17
Edge-on discs offer a unique opportunity to probe radial and vertical dust and gas distributions in the protoplanetary phase. This study aims to investigate the distribution of mic…
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…
DRAGyS -- A comprehensive tool to extract scattering phase functions in protoplanetary disks
Maxime Roumesy, François Ménard, Ryo Tazaki +3
The early stages of planet formation, involving dust grain growth and planetesimals formation, remain shrouded in mystery. The analysis of the Scattering Phase Function (SPF) measu…
The role of absorption and scattering in shaping ice bands. Spatially-resolved spectroscopy of protoplanetary disks
Laurine Martinien, Gaspard Duchêne, François Ménard +2
The James Webb Space Telescope now enables the spectral study of ices with unprecedented sensitivity and angular resolution. Water ice plays a crucial role in the growth of grains…
JWST Imaging of Edge-on Protoplanetary Disks. IV. Mid-infrared Dust Scattering in the HH 30 disk
Ryo Tazaki, François Ménard, Gaspard Duchêne +10
We present near- and mid-infrared (IR) broadband imaging observations of the edge-on protoplanetary disk around HH 30 with the James Webb Space Telescope/Near Infrared Camera (NIRC…
