Context. Reference-star differential imaging (RDI) is a promising technique in high-contrast
imaging that is thought to be more sensitive to exoplanets and disks than angular differential …

Context. The diverse morphology among protoplanetary disks may result from planet-disk
interactions, suggesting the presence of planets undergoing formation. The characterization …

Context. Observations of debris disks have significantly improved over the past decades,
both in terms of sensitivity and spatial resolution. At near-infrared wavelengths, new …

Context. Multiwavelength scattered light imaging of debris disks may inform dust properties
including typical size and mineral composition. Existing studies have investigated a small …

Direct imaging of exoplanets is particularly challenging due to the high contrast between the
planet and the star luminosities, and their small angular separation. In addition to tailored …

Abstract The Gemini Planet Imager (GPI) has excelled in imaging debris disks in the near-
infrared. The GPI Exoplanet Survey imaged 24 debris disks in polarized H-band light, while …

HD 53143 is a mature Sun-like star and host to a broad disk of dusty debris, including a cold
outer ring of planetesimals near 90 au. Unlike most other inclined debris disks imaged at …

Context. 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 …

Azimuthally asymmetric structures have been discovered in millimeter continuum emission
from many protoplanetary disks. One hypothesis is that they are vortices produced by the …

Context. Debris disks have commonly been studied around intermediate-mass stars. Their
intense radiation fields are believed to efficiently remove the small dust grains that are …
