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…
Searching for Axion-like particle Dark Matter with Time-domain Polarization: Constraints from a protoplanetary disk
Kanako Narita, Tomohiro Fujita, Ryo Tazaki +1
Axion-like particles (ALPs) can induce a birefringence effect that rotates the polarization angle of light, offering a probe of ultralight dark matter. We analyze archival near-inf…
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…
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…
Insight from laboratory measurements on dust in debris discs
Julien Milli, Olivier Poch, Jean-Baptiste Renard +11
Extreme adaptive optics instruments have revealed exquisite details on debris discs, allowing to extract the optical properties of the dust particles such as the phase function, th…
The polarisation properties of the HD 181327 debris ring. Evidence for sub-micron particles from scattered light observations
Julien Milli, Elodie Choquet, Ryo Tazaki +26
Polarisation is a powerful remote-sensing tool to study the nature of particles scattering the starlight. It is widely used to characterise interplanetary dust particles in the Sol…
