The disks that orbit young stars are the essential conduits and reservoirs of material for star
and planet formation. Their structures, meaning the spatial variations of the disk physical …

Direct images of protoplanets embedded in disks around infant stars provide the key to
understanding the formation of gas giant planets such as Jupiter. Using the Subaru …

Abstract Herbig Ae/Be stars are young contracting stars on the radiative track in the HR
diagram on their way to the main sequence. These stars provide a valuable link between …

We present the first part of our Disks ARound T Tauri Stars with SPHERE (DARTTS-S)
survey: observations of eight T Tauri stars that were selected based on their strong (sub) …

High-contrast adaptive optics (AO) imaging is a powerful technique to probe the
architectures of planetary systems from the outside-in and survey the atmospheres of self …

We present results from the first population synthesis study of protostellar discs. We analyse
the evolution and properties of a large sample of protostellar discs formed in a radiation …

Gravitational forces are expected to excite spiral density waves in protoplanetary disks, disks
of gas and dust orbiting young stars. However, previous observations that showed spiral …

Context. The study of dynamical processes in protoplanetary disks is essential to understand
planet formation. In this context, transition disks are prime targets because they are at an …

We present high-resolution, H-band imaging observations, collected with Subaru/HiCIAO, of
the scattered light from the transitional disk around SAO 206462 (HD 135344B). Although …

Context. Understanding the diversity of planets requires studying the morphology and
physical conditions in the protoplanetary disks in which they form. Aims. We aim to study the …
