Since Protostars and Planets VI (PPVI), our knowledge of the global properties of
protoplanetary and debris disks, as well as of young stars, has dramatically improved. At the …

The direct characterization of exoplanetary systems with high-contrast imaging is among the
highest priorities for the broader exoplanet community. As large space missions will be …

To date, nearly two hundred planet-forming disks have been imaged at high resolution. Our
propensity to study bright and extended objects does, however, bias our view of the disk …

Context. In recent decades, direct imaging has confirmed the existence of substellar
companions (exoplanets or brown dwarfs) on wide orbits (> 10 au) around their host stars. In …

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 …

Planetary debris disks around other stars are analogous to the asteroid and Kuiper belts in
the Solar System. Their structure reveals the configuration of small bodies and provides …

We know little about the outermost exoplanets in planetary systems because our detection
methods are insensitive to moderate-mass planets on wide orbits. However, debris discs …

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

The detection and characterization of extended structures is a crucial goal in high-contrast
imaging. However, these structures face challenges in data reduction, leading to over …

The vertical structure of debris discs provides clues about their dynamical evolution and the
collision rate of the unseen planetesimals. Thanks to the ever-increasing angular resolution …
