JWST Imaging of Edge-on Protoplanetary Disks. V. Flux Ratio Reversal and Disk-edge Structure in the Flying Saucer
Jie Ma, Karl R. Stapelfeldt, Marion Villenave +8
We present near- and mid-infrared broadband imaging observations of the edge-on protoplanetary disk 2MASS J16281370-2431391, a.k.a. the 'Flying Saucer', obtained with NIRCam and MI…
The dust in Sauron's eye - Observational and experimental results on the debris disk around HR 4796
M. Bonduelle, J. Milli, O. Poch +14
The optical properties (scattering phase function SPF; degree of linear polarization DoLP; reflectance) of the dust particles orbiting in debris disks can be retrieved through scat…
Probing dust properties through polarized scattered-light images of a sample of ring-shaped protoplanetary disks
Maxime Roumesy, François Ménard, Gaspard Duchêne +2
The evolution of protoplanetary disks, especially in the early stages of planetary formation, as dust grows, is the cornerstone of the birth of planets. The mechanisms involved in…
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…
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…
