We review recent works on the dynamics of circumbinary accretion, including time variability,
angular momentum transfer between the disk and the binary, and the secular evolution of …

Observational advances over the last decade have enabled high-resolution, interferometric
studies of forming multiple systems, statistical surveys of multiplicity in star-forming regions …

We review the role of stellar flybys and encounters in shaping planet-forming discs around
young stars, based on the published literature on this topic in the last 30 years. Since most …

We report spectro-polarimetric results of an observational campaign of the bright neutron
star low-mass X-ray binary Cyg X-2 simultaneously observed by IXPE, NICER, and …

Constraining the physical and chemical structure of young embedded disks is crucial for
understanding the earliest stages of planet formation. As part of the Early Planet Formation …

After decades of fast-paced technical advances, optical/infrared (O/IR) interferometry has
seen a revolution in recent years:▪ The GRAVITY instrument at the Very Large Telescope …

Accumulation of new data on stellar hierarchical systems and the progress in numerical
simulations of their formation open the door to genetic classification of these systems, where …

Accretion disks around black holes power some of the most luminous objects in the
universe. Disks that are misaligned to the black hole spin can become warped over time by …

Arc-and tail-like structures associated with disks around Herbig stars can be a consequence
of infall events occurring after the initial collapse phase of a forming star, consistent with the …

We present the complete sample of protoplanetary disks from the Gemini-Large Imaging
with the Gemini Planet Imager Herbig/T Tauri Survey, which observed bright Herbig Ae/Be …
